Hog Slat - Canada: BlogBloghttps://hogslat.ca/Thu, 28 Mar 2024 21:40:08 GMTurn:store:1:blog:post:35https://hogslat.ca/comparing-17-year-old-slatsComparing 17 Year Old Slats<p style="text-align: justify;">I have sold or been involved with swine concrete slats for over 30 years.  For the last 18 of those years I have represented Hog Slat products.  I believe that our slats are the best in the industry and have the most consistent quality. But new slats all look good when they are getting unloaded off the delivery truck. What about when they are 5 years or 10 years or even older?</p> <p style="text-align: justify;">Last week I was at  Hog Slat’s production plant in Humboldt, Iowa taking pictures of slats.  The plant manager, Dave Shiflett said “You want to see some old slats that we pulled out of a barn recently?”</p> <p style="text-align: justify;">“Sure”</p> <p style="text-align: justify;">So we go out behind the plant and he explained that we were called in to replace some slats from local production site.  This particular site was built in 1994. One barn has slats produced by Hog Slat and the other barn has slats from a competitor.</p> <dl id="attachment_187"></dl> <div style="text-align: justify;"> <div id="attachment_187" class="wp-caption alignnone"><img class="size-medium wp-image-187 " title="comparing slats" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2011/05/slat-compar-top1-300x225.jpg" alt="" width="300" height="225" /> <p class="wp-caption-text">Comparing slats</p> </div> </div> <dl id="attachment_187"><dt></dt></dl> <p style="text-align: justify;">He said “The slat on the left is a Hog Slat slat and the one on the right is from the competitor.  Notice the difference in surface wear on each slat.  The competitor’s slat has rock showing because the top surface has been eaten or worn away.  I grabbed our slat out of the other building that they were not replacing for comparison.”</p> <p style="text-align: justify;">“Interesting, but they’re not from the same building”</p> <p style="text-align: justify;">“No but same site which means same water, same feed and same management.  Pretty good comparison of 17 years old slats I would say”</p> <p style="text-align: justify;">So we started talking about the reasons for the better wear on the Hog Slat product.</p> <p style="text-align: justify;">Dave said “It’s the denser concrete we use in our mix.  Everybody that has ever poured any concrete knows the less water you use in mixing concrete, the harder, stronger concrete you get.  The standard mix is a 4” slump, which you have to use to be able to place and screed the concrete in the form.  We use a ZERO SLUMP mix in our slats. Let me show you what I mean inside.”</p> <p style="text-align: justify;">So we go inside and Dave has slump cone in which he places some of our concrete mix and pulls the cone. He adds water to an additional batch to represent a standard 4” concrete mix.</p> <div style="text-align: justify;"><dl id="attachment_188"></dl> <div></div> <div id="attachment_188" class="wp-caption alignnone"><img class="size-medium wp-image-188 " title="concrete slump" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2011/05/slump1-300x225.jpg" alt="" width="300" height="225" /> <p class="wp-caption-text">concrete slump</p> </div> </div> <p style="text-align: justify;">“Note how the concrete mix on the right has sagged down 4” vs. the zero slump concrete on the right? All the rest of the slat manufacturers have to use a wetter mixture because they don’t have equipment that allows them to work a drier mix. Like I said earlier less water means a stronger, denser concrete that wears better and holds up longer in the barns.”</p> <p style="text-align: justify;">As the industry’s production buildings get older this comparison bears keeping in mind.  Most new slats look the same when they are placed in the barn and you really can’t tell the difference from the outside. Buying slats for a new building or replacements in an existing structure is an important decision that producers should take under careful consideration.  Looking at 17 year old slats is a chance to get some valuable insight that may help with that decision.</p>urn:store:1:blog:post:34https://hogslat.ca/the-ultimate-slat-saverThe Ultimate Slat Saver<p style="text-align: justify;">While at Dustin Anderson’s site last week reviewing his sort barn conversion, one thing quickly drew my attention.  When the barn was constructed, the builder installed plastic slat mats which are considered “best practice” in our industry.  Look at the result 6 years later in the pictures above.</p> <p style="text-align: justify;">All the plastic slat mat did was move the problem out 12 inches!   Now, this is not terrible slat wear for six years of usage, but it will get worst.  A bigger mat could be placed under the feeder, but this would just move the problem out a little more.  The best solution to this problem isn’t a mat at all.  The ultimate slat saver comes in a bucket!  Hog Slat offers a product called Armor-Rock.  Armor-Rock is a two part epoxy with blended aggregates that form a wear and chemical resistant coating to protects the slat’s surface.   The liquid epoxy mixture is applied to the slat’s surface and then sand is broadcast on top to create a non-slip surface.</p> <p><img class=" size-medium wp-image-572 alignleft" title="armor rock" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2012/06/armor-rock-300x224.jpg" alt="" width="300" height="224" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">A huge advantage to using the Armor-Rock is it doesn’t cover the slat openings around the feeders.  Urine, water and feed wastes fall through because the normal slat opening remains intact.  Corrosive wastes are not collecting and just getting moved farther out on the slats, which is the problem with conventional slat mats.</p> <p><img class="alignnone size-medium wp-image-574" title="1 Eroded Slats" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2012/06/1-Eroded-Slats-300x225.jpg" alt="" width="300" height="225" style="display: block; margin-left: auto; margin-right: auto;" /><img class="alignnone size-medium wp-image-575" title="armor rock after" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2012/06/armor-rock-after-300x225.jpg" alt="" width="300" height="225" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">There is one slight disadvantage to using Armor-Rock over standard plastic slat mats.  It’s not the cost of the material; if Armor-Rock is purchased in bulk the price is virtually the same.  The key issue is the time it takes to install it under a feeder. When mats are used they are placed under the feeders, the gating is installed, and the installation is complete. With Armor-Rock, the feeders and gating are completely installed and then the feeders must be removed.  The epoxy is mixed, placed on the flooring and allowed to dry.  After the Armor-Rock cures, the feeders are replaced in the gating.   Because of the extra labor the Armor-Rock option is not offered by most contractors.</p> <p style="text-align: justify;">The choice is yours to make.  Chose the Ultimate Slat Saver with Armor-Rock and do it once or chose standard slat mats and fix it later.  You can pick up Armor-Rock at any Hog Slat store.</p>urn:store:1:blog:post:33https://hogslat.ca/good-slat-design-aid-in-preventing-swine-lamenessGood Slat Design Aid in Preventing Swine Lameness<dl id="attachment_2140" class="wp-caption aligncenter"><dd class="wp-caption-dd">Totally slatted concrete flooring used in group sow housing.</dd></dl><br /> <p>With the majority of U.S. pigs finished in confinement style facilities, a 12-pound weaned pig will spend at least four months on slatted concrete floors. As the industry moves from gestation stalls to group housing designs, slat quality becomes an important factor. Rather than being confined to a small slatted area, sow movement over an entire slatted pen subjects them potential injury from defective flooring design.</p> <p>Good concrete slat design, construction, and maintenance can minimize foot and leg problems associated with swine production.</p> <p>The most critical feature in slat design is producing slats with a flat top surface.  Slats with uneven and inconsistent surface place additional stress on pig’s feet and joints.</p> <div id="attachment_2226" class="wp-caption aligncenter"><img class="size-large wp-image-2226" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2016/01/hand-cast-vs-machined-slats_edit_web-1024x300.jpg" alt="Level top provides surface that is easier on pig's feet and joints." width="690" height="202" /> <p class="wp-caption-text">Level top provides a surface that is easier on pig’s feet and joints.</p> </div> <p>Many methods used for producing concrete slats consist of placing wet cast concrete into multiple steel forms and hand troweling to finish.  It is harder to build slats with a consistently flat surface by hand finishing methods.</p> <p> </p> <div id="attachment_2162" class="wp-caption aligncenter"><img class="size-large wp-image-2162" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2016/01/rotoscreed_web-1024x683.jpg" alt="Rotoscreen &quot;striking off&quot; dry cast concrete on mold to apply flat surface on slats.

Slats built using concrete with a low water-to-cement ratio are longer lasting and more resistant to wear.</p> <p>The water-cement ratio refers to the ratio of the water weight to the cement weight used in a concrete mix. A lower ratio leads to higher strength and durability but makes the mix difficult to work with and form. For this reason, most slats are produced with wet cast concrete using a water-cement ratio of 0.5. Machined slats are manufactured from dry cast concrete with a water-cement ratio of less than .39.</p> <p><img class="aligncenter size-large wp-image-2228" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2016/02/Cement-Water-Ratio_web-1024x523.jpg" alt="Cement-Water-Ratio_web" width="690" height="352" /></p> <p>A cubic yard of wet cast concrete formulated with 500 pounds of cement contains 250 pounds of water, while a dry cast mix only contains 195 pounds. As the excess water leaves during the curing process, it creates microscopic pores that reduce the final strength of a slat. Compromised slat strength can lead to many problems down the road, including expensive repairs, equipment damage and injury to pigs and farm personnel.</p> <dl id="attachment_2143" class="wp-caption aligncenter"><dt class="wp-caption-dt"><img class="wp-image-2143 size-large" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2016/01/Concrete-slat-repair-1024x318.jpg" alt="Wet cast slats by feeder showing exposed aggregate damage." width="690" height="214" /></dt><dd class="wp-caption-dd">Wet cast slats by feeder showing exposed aggregate damage and repaired surface with Vanberg Specialized Coatings. </dd></dl> <p>Maintaining surfaces and edges of slats, as they wear over time, is essential in providing pigs with a comfortable flooring surface. Areas around waterers and feeders are the first to show significant damage. When the need arises for concrete slat repair, choose a repair mortar designed for slat repair versus generic concrete repair products. Mortars designed for slat repairs feature cement and epoxy formulations with higher cure strengths and faster cure times. The amount of damage will determine the type of repair product needed. For simple repairs, less than 1/4″ in depth, a cost effective cement mortar can be used. More severe corrosion requires the use of epoxy mortars to hold the repair patch in place. Hog Slat offers a complete range of concrete repair products from Vanberg Specialized Coatings that can be used to repair worn and damaged slats with minimal downtime. For more information on slat repairs see the DIY video at http://www.hogslat.com/con-korite-xtra-mortar-kit.</p> <p>Choosing concrete slats with a level surface and uniform openings provide growing pigs and group housed sows with secure footing to minimize foot and joint injuries.</p> <p>To learn more about Hog Slat’s machine produced slats go to <a href="http://www.hogslat.ca/concrete-slats">http://www.hogslat.ca/concrete-slats</a>.</p>urn:store:1:blog:post:32https://hogslat.ca/2nd-generation-stanchions2nd Generation Stanchions<p>The pen gestation continues to evolve as producers gain "real world" experience managing production systems.  </p> <p>In 2012 Prestage Farms remodeled an existing finishing complex into breeding and farrowing units and installed stanchions in the pen gestation. You can read more about the remodel project <a href="http://www.hogslat.ca/prestage-selects-stanchions-for-remodel-project">here.</a>   Production Manager, Russ Goss, explained some of the changes made in new sow units built this year,   "In the new facilities, we increased the square footage from 19.5 to 23 per sow, and the stanchion width changed from 19" to 24" on center. In addition, the rodded stanchion dividers were increased from 18” to 48”.</p> <p>"Extending the dividers changed the behavior of the dominant sows in a pen. Shorter dividers enabled the boss sow to disturb the other animals, and you would see some of them repositioning during the feeding period. The 48" divider prevents the aggressive animals from reaching the shoulders of their pen mates. Instead of going down the line and disrupting other animals, they quickly figure out they can't move anybody and just return to their spot."</p> <p>"The other thing we see is at any one time 50% of the animals in a pen will be lying in the stanchions.   They never laid in the shorter stanchions, but would always be lying around the "donut" in the middle with their backs against the pen perimeter gating.   A sow always wants to lay with her back against something. She feels secure in the longer stanchions and she appears comfortable staying there, but is also free to leave and move around the pen." <span style="text-decoration: line-through;"> </span> Russ continued, “We have noticed that after the initial fighting to establish the pecking order in the pen, the sows are noticeably calmer and quieter compared to our stall barns.”</p> <p>"Using pen gestation with stanchions fits our system and personnel. The ESF systems are really an intriguing concept... being able to feed and track sows individually in loose housing. Maybe it's our genetics, but I don't think it's that important for us to feed a sow individually all the way through gestation. From our experience, we can effectively condition the sow the first 6 weeks in gestation. However, if we do not have all sows in the ideal condition, we will group them together and set all feeders in the pen accordingly.</p>urn:store:1:blog:post:31https://hogslat.ca/sow-stanchions-offer-producers-another-choice-for-gestationSow Stanchions Offer Producers Another Choice for Gestation<p style="text-align: justify;"><img class="alignleft size-full wp-image-112" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2010/11/Angle-top-stanchion-002.jpg" alt="" width="320" height="240" style="float: left; padding: 10px;" />As the swine industry searches for alternatives to stall gestation, another option has emerged and is in the process of being refined.  Stanchion Housing refers to short stall-like dividers that are added to open pen gestation to separate and protect the animals as they are fed.  It is a refinement over traditional open pens where sow are fed on the floor and group size must be limited to reduce fighting.</p> <p style="text-align: justify;">To date all the systems have been designed with standard gestation stalls in which the sows are weaned and remain until they are bred and preg checked.  Typically this would be about a 45 day inventory of the total sow numbers.</p> <p style="text-align: justify;"><img class="alignright" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2010/11/Angle-top-Stanchions-003.jpg" alt="" width="320" height="240" style="float: right; padding: 10px;" />Looking at the total number of animals in a breeding group, a decision can be made on total numbers of sows per pen.  Current stanchion systems range from 10 head per pen all the way up to over a hundred.  Many producers choose to break a farrowing group into two or three different pens as this allows for grading and sorting weaned animals by body score.  Placing sows in similar groups reduces fighting and allows for uniform feeding.</p> <p style="text-align: justify;">After total number of sows per pen is determined, the next design consideration is the amount of square footage per animal.  Current EU welfare regulations require 24 sq ft. and some producers have chosen to follow that guideline, but systems exist that range from this level all the way down to 17 sq ft./sow.</p> <p style="text-align: justify;">Two critical design elements have proved themselves in the existing layouts.  <img class="size-full wp-image-114 alignleft" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2010/11/Pen-Detail.jpg" alt="" width="320" height="256" style="float: left; padding: 10px;" />First, long narrow pens are preferred as this prevents a boss sow from blocking feed stanchions.  The second design feature is placing the stanchions head to head in the center of the pen rather than placing them along the alleys.  Because the stanchions are not in the alleys, the sows can be viewed from the rear during feeding for problems.  It also allows for easier animal movement in and out of the pens as the gates are not part of the stanchions.  In addition, the number of feed lines needed is reduced.</p> <p style="text-align: justify;">The first stanchion systems featured trickle feed equipment where the feed slowly dribbled in front of the sows at meal time, the idea being a slow placement of feed in front of the sows would hold them in the stalls and prevent boss sows from “wolfing down” their feed and moving up and down the line stealing feed.    In practice, the additional cost and upkeep of a trickle system did not justify its use and has been omitted on new installations.   Current systems use standard feed drops that dump the entire ration into stainless steel troughs or on a solid concrete floor.</p> <p style="text-align: justify;"><img class="alignright size-full wp-image-121" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2010/11/Angle-top-Stanchions-005.jpg" alt="" width="320" height="240" style="float: right; padding: 10px;" />Equipment used in a head-to-head layout consists of stanchions that are 40” tall and 19” long.  These dimensions protect the face and ears of the individual sow from aggressive pen mates.  Ideal width has been determined to be 20” as this prevents other sows from crowding in to steal feed.   Early systems used solid dividers; as we gained more experience with head-to-head systems,  the use of open dividers was adopted.   The Hog Slat equipment used to configure this layout is an adaption of our standard gestation stall which has been used throughout the industry for over 30 years.  The stanchions are constructed of solid horizontal rods with angle top and bottom rails, the entire unit bolts together with galvanized floor spacers and double top spacers for added stability. This style of stanchion fits completely with the standard 40” gestation penning used in the rest of the pen layout.   The result is a well-designed system that goes together without a great deal of “field fabrication”. AquaChief cup waterers are added at the rate of one per 11 animals to provide fresh water.</p> <p style="text-align: justify;"><img class="alignleft" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2010/11/Angle-top-stanchion-004.jpg" alt="" width="240" height="320" style="float: left; padding: 10px;" />Many of the stanchion systems are remodels, the layout of which has to be adapted to existing slat /solid configurations. If building new projects most producers opt for using total slats as this allows for more flexibility in the event of changes in the welfare regulations.</p> <p style="text-align: justify;">Stanchion systems require a high degree of stockmanship to operate successfully.  Boss sows must be culled ruthlessly and individual care of animals is more difficult than standard stall systems.  However, for many production systems, stanchions are a better alternative than Electronic Sow Feeding. Stanchions allow group housings of animals without the costs and high maintenance associated with ESF stations.</p> <p style="text-align: justify;">For more information please contact your local Hog Slat rep or contact us by email at <a href="mailto:frichards@hogslat.com">frichards@hogslat.com</a>.</p>urn:store:1:blog:post:30https://hogslat.ca/alternative-sow-housingAlternative Sow Housing<p>As the food industry responds to animal welfare issues, many producers have started to consider alternative options to stall-based gestation systems. We took a few moments to speak with Hog Slat’s national sales manager, Fritz Richards, about group housing systems.<br /><br /><strong>Can you describe the options available and the advantages and disadvantages of each?</strong><br />Hog Slat first took a hard look at the Electronic Sow Feeding or ESF systems. Sows are housed as groups and fed in stations that identify sows individually by means of RFID ear tags. This type of equipment seemed to offer slight advantages that would offset some of the management tools which producers would lose going to group housing from stalls. Such as the ability to feed animals as individuals and maintain dynamic farrowing groups. We looked at both domestic and international systems, touring and speaking with experienced growers. There were some differences that came to the forefront.</p> <p><strong>Like?</strong><br />This type of system is a major paradigm shift for US producers. The US industry has developed a very straight forward system of handling gestation sows. Sows are weaned into a stall, bred there and sow condition is managed by individual feeding. ESF is a completely different management style. First, the animals must undergo a two to four week training process with up to five percent of them eliminated as untrainable. Second, because computers, scanners, RFID tags and low voltage lines are necessary for ESF equipment a highly trained staff is required to operate the system successfully. With many production systems experiencing high turnover of farm staff, it becomes very difficult to perform the necessary maintenance and training.</p> <p><strong>Where do you see ESF working best?<br /></strong>Farms where the owner works in the unit every day and is able to maintain and repair the equipment in-house. The U.S. landscape is not like the situation we saw in Europe where as many as six service technicians are available in an area the size of a U.S. county. Getting timely repairs when the equipment is down should be an important consideration when considering ESF systems.</p> <p><strong>What other options have you looked at?</strong><br />Free Access Stalls. In this system, the sows are housed in groups but are provided with access to individual feeding stalls. The stalls have a lockout mechanism on the rear gate that allows sow access and prevents other sows from entering. She is able to exit the stall at any time to go back in the pen area. Most designs feature an option for the herdsman to lock the sows in the stalls for treatment. We feel this may be the ultimate sow housing system.</p> <p><strong>Are Free Access Stalls available from Hog Slat?</strong><br />We offer this equipment to producers, but, they need to remember that this is the most expensive option they can install. The square footage requirements per sow are high, (as much as 37 sq ft per sow) and the stalls with a locking mechanism are more expensive than a standard gestations stall.</p> <p><strong>What other options are available?</strong><br />Floor feeding in pens actually predates stalls. This system is designed with five to eight sows per pen, and the feed is dropped directly on the pen floor. This system is successful if managed correctly. Grouping of the sows by size is critical as the strongest animals tend to get the most feed. It is the lowest cost alternative to gestation stalls.</p> <p><strong>What seems to be the most popular option?</strong><br />Stanchions are the most popular system we see for new and remodel projects. This is group housing with short dividers or stanchions to protect the individual sow at feeding time. This design lends itself to a wide range of group sizes with a lot of flexibility in pen and building dimensions, which is important with remodel projects.</p> <p><strong>Why do you think it is so popular?</strong><br />Stanchion production methods adapt well to current U.S. production practices. A farm’s current staff can manage a stanchion system because it utilizes the same feed delivery system and penning equipment as they are currently using.</p> <p><strong>What criteria are used in designing a stanchion system?</strong><br />The first decision is how many square feet per sow will be allocated. Obliviously, square footage in the building is expensive, and this can range from 17 to 24 square feet per animal. This is a business decision each producer must weigh against projected welfare regulations.<br />A group sizing of 10 to 20 head per pen is common. Equipment is standard 40-inch high rod panels with 18” long divider stanchions, creating a feed space for each animal in the pen. The stanchions are open rod style set at 18” to 21” width. Experience has shown it is not necessary to use solid dividers on the side or front of the stanchion. The rod style protects the ears and head of the sow from aggressive animals and doesn’t restrict air flow as much as solid panels. In addition, rod style penning is more cost effective and has a longer life span.<br />We also design a breeding area with stalls equal to 45 days worth of sow holding capacity. Sows are weaned into this area until bred and formed into gestation groups.</p> <p><strong>How is the stanchion system managed?</strong><br />Sows are fed using an automated feed system with individual drops. Sows anticipate each feeding and start lining up before the feed drops. You don’t see much shuffling between stanchions as they become conditioned to eating their portion and realize the other feeding slots will not have feed after they finish. The earliest systems utilized a trickle feed system where over a longer time, small amounts of feed were dispensed to hold the sow at their feeding space. Trickle feeding was proven to be unnecessary and just added additional cost to the scheme.<br />While the sows are eating, a herdsman moves along the alley noting animals that are not at the feed trough. He can mark them for later treatment or movement to a hospital area.</p> <p><strong>Are there any disadvantages?</strong><br />Yes, animals cannot be individually fed. Sows that “fall out” of a group because of sickness or injury have to be removed to a hospital pen or stall. Despite the disadvantages, this has been a popular choice for many producers desiring to move into group housing.</p> <p><strong>How many stanchions have been installed by Hog Slat?</strong><br />Hog Slat has built and installed over 150,000 spaces of stanchion housing in the U.S., from individual farms up to large production systems. We have gathered a lot of field experience completing those projects and can help any producer considering group housing systems.</p>urn:store:1:blog:post:29https://hogslat.ca/prestage-selects-stanchions-for-remodel-projectPrestage Selects Stanchions for Remodel Project<p style="text-align: justify;">When Bryan Foods announced their decision to close the state’s only slaughter plant, Prestage Farms in Mississippi changed the structure of their existing operation. Part of the complex was converted to breeding stock production to supply gilts to other company farms. In addition, Prestage launched a unique plan in 2012 to convert some of the existing finishing sites to breeding, gestation and farrowing.</p> <p style="text-align: justify;">Russ Goss, Production Manager along with Todd Griffin, the operation’s Maintenance Manager gave us the details of the conversion.</p> <p style="text-align: justify;">The original finishing sites consist of eight, 40’ x 176’8” buildings designed  to hold 880 head of market hogs.</p> <p><img class="alignleft wp-image-1790" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2013/11/site-drawing-PUB-file-800x566-2.jpg" alt="site drawing PUB file (800x566) (2)" width="428" height="303" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">First part of the plan consisted of creating a dedicated breeding site at one former finishing site. One of the buildings was left unchanged and used as an isolation unit, with only the original 30″ penning swapped out for 40″ high gestation gates.  The other seven buildings were switched over to breeding with each holding 336 stalls. The sows remain in the stalls for 42 days after breeding. After preg-checking, the sows are trucked to one of the converted gestation/farrowing sites. The gestation and farrowing sites were retrofitted using four of the buildings as farrowing and four as gestation. Each gestation barn is sized to fill two of the farrowing buildings.</p> <p style="text-align: justify;">The gestation floor plan lays out 20) 15’10” wide x 18’6” deep pens with 24) gestation stalls located on one end. . Each pen is designed to hold 14 sows allowing for 21 square foot per animal. Each pen has five feeding stanchions located along the center alley and ten on the outside wall.</p> <p><img class="alignleft wp-image-1791" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2013/11/PRESTAGE-MISSISSIPPI-single-2-1_edited-1.jpg" alt="PRESTAGE MISSISSIPPI single) (2)-1_edited-1" width="692" height="188" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p><img class="alignleft wp-image-1793" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2013/11/stanchion-sows-eating-800x533.jpg" alt="stanchion sows eating (800x533)" width="600" height="400" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Adjustable feed drops drop the rations into the stainless steel trough below.</p> <p style="text-align: justify;">When we asked Russ about the decision to go with pen system versus stalls, he explained, “We feel stanchions are the best choice for group housing compared to the ESF options that we looked at. We think stanchions are easier for our staff to manage and there is less equipment to maintain and repair.”</p> <p style="text-align: justify;">Russ commented, “The sows adapt to the stanchions fairly well. There’s some fighting the first day we put them together, but they settle down after that. Without a doubt group housing requires a higher level of stockmanship from our people, but the farm staff has learned to manage the system without a lot of trouble.”</p> <p><img class="alignleft size-full wp-image-1794" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2013/11/farrowing-crates-800x521.jpg" alt="farrowing crates (800x521)" width="800" height="521" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Crews removed the old slats and equipment, after opening up a section of the end wall. Supported by the existing slat walls, trussed TriDek flooring spans the entire building with traction brakes located in the center of the crate providing the sows with better footing. Four rows of 33 farrowing crates were installed on the flooring for a total capacity of 132.</p> <p style="text-align: justify;">Prestage selected a 5’x 7’ Advantage finger style crate with stainless steel rear door panels and SowMAX dispensers above the feeders. Four feed lines run the length of the building to fill the dispensers.</p> <p style="text-align: justify;"><img class="alignleft wp-image-1795" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2013/11/sow-max-closeup-683x1024-683x1024.jpg" alt="sow max closeup (683x1024)" width="282" height="423" style="float: left; padding: 10px;" />Russ explained Prestage’s previous experience with SowMAX, “We just do a better job feeding sows in lactation with the SowMAX. It eliminates any guess work; we just fill the hoppers twice a day and the sows eat to appetite. They can eat at night during hot weather, and we know they are getting all the feed they want even on the weekends.”</p> <p style="text-align: justify;">He continued “Improved sow body condition is one of the biggest benefits we get from using SowMAX.

This arrangement allows long-term flexibility to reconfigure the pen layout in the future if needed.</p> <p>Group housing with stanchions is the predominant type of housing under construction this year. Largely through trial and error, the industry seems to have settled into pen configurations containing eight to twelve sows. This pen size permits closer grouping by size and condition and promotes easier visual inspection.</p> <p>Whether the production system chooses gestation stalls, stanchions, or ESF, most equipment is specified with hot-dipped galvanized equipment instead of painted finish. The extended equipment life provided by the galvanized finish makes this an economical business decision.</p> <p>One advantage reported with stanchion systems is longer equipment life resulting from moving the water away from the front of the stanchions.

Longer framed sows and reduced piglet crushing rates from using wider pens have driven this trend. Again, the equipment will have a galvanized finish with a combination of cast iron, TriDek, or plastic slats for flooring choices.</p> <p>Most production systems will incorporate some provision for ad-lib sow feeding. Besides reducing farm labor, ad-lib sow feeding is the most efficient method for feeding individual sows to reach full milk production potential.

Here are some tips to keep your houses running at peak efficiency.</strong></p> <p style="text-align: justify;"><strong>1) Bleed off water to control mineral content</strong></p> <p style="text-align: justify;">As water is circulated and evaporated in a pad system the concentration of minerals is increased.  This is especially true in areas that have hard water with its higher levels of dissolved minerals. It is suggested that 5% to 10% of the circulated water should be continuously bled out of the system. Alternatively you can also dump and replace the sump tank water weekly. Products such as Scale-Stop or Cool-N-Kleen Cool Cell Descaler can be effective in controlling scale buildup for farms with very hard water when coupled with bleed off.</p> <p style="text-align: justify;"><strong>2) Check pH</strong></p> <p style="text-align: justify;">Desired pH level of the water should be between 6 and 9.  The pH levels outside of the this range shorten pad life by leaching out the stiffening agents in the pad. You can alter the pH of the water by adding one of <img class="size-full wp-image-172 alignright" title="H2Pad" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2011/03/H2Pad-Upright-adj-clipped-FINAL.jpg" alt="" width="144" height="565" style="float: right; padding: 10px;" />the descaler agents listed above or Grower Select’s Kool-Cell Kleen.</p> <p style="text-align: justify;"><strong>3) Eliminate dry spots on the pad</strong></p> <p style="text-align: justify;">Dry areas on the pads allow uncooled air to enter the building.  Simply put,  if the pad’s not wet it’s not cooling. Dry streaked areas on the pad are a clear sign that you have clogged holes in the distribution system.  Remove the cover and unstop the clogged holes in the header system.  It is a good practice to clean the distribution system by opening the ball valves and flushing water through at least once a month.</p> <p style="text-align: justify;"><strong>4) It’s a pain…but you have to clean the filters</strong></p> <p style="text-align: justify;">Install a spin down water filter with a clear housing and 60 mesh screen on the system and keep it clean. It will prevent clogged distribution pipes and dirty pads. The poorer the water quality the more often the filters need to be cleaned. Installing a filter with a ball valve will simplify the chore.</p> <p style="text-align: justify;"><strong>5) Prevent algae growth</strong></p> <p style="text-align: justify;">Although H2PADs are treated with an fungicide and come with ProTech edging to prevent algae from adhering to the pad surface, this does not completely eliminate the problem.  Treat the system  water with a good preventive product like Bio-Stop or Grower Select’s Kool-Cell Kleen to keep algae under control. In addition,  the pads should be allowed to dry out once every 24 hours to improve the longevity of the pad.  Program your ventilation system to allow the fans to continue to run awhile after the pad system is turned off at night.  This will pull air through the system, drying the pads out and killing any algae spores.</p>urn:store:1:blog:post:25https://hogslat.ca/jet-or-submersible-pump-for-cool-cell-systemsJet or Submersible Pump for Cool Cell Systems?<p style="text-align: center;"><img class="aligncenter wp-image-1653 size-full" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2015/04/jet-vs-sub-pump-e1527339434560.jpg" alt="jet vs sub pump" width="600" height="300" /></p> <p style="text-align: justify;">We spoke with Hog Slat engineers, Tyler Marion and Tim King about the differences between using a jet or submersible pump to fill evaporative cooling systems. Here’s a quick synopsis of our discussion.</p> <p style="text-align: justify;">1) Jet pumps are more reliable because they can run dry for a period of time. For instance, if you discover during morning chores a leak occurring overnight had drained the system, a jet pump would still be working.   A submersible pump that runs that long without water will need to be replaced.</p> <p style="text-align: justify;">2) Jet pump repairs are less costly. The impeller and motor are two individual components; a bad motor can be replaced separately. Submersible pumps are a single unit.</p> <p style="text-align: justify;">3) Jet pump repairs and service are easier. A jet pump system is all above ground…a submersible pump must be pulled from the sump for repairs. A drain plug on the GrowerSELECT jet pump allows easy access for service and winterizing.</p> <p style="text-align: justify;">4) The integrated trash basket on a jet pump protects the pump from debris.</p> <p style="text-align: justify;">5) Submersible pumps are designed to move waste water from underground applications; low volumes with high head pressures. Jet pumps are a better choice for evaporative cooling applications as they move larger volumes of water at reduced head pressures.</p> <p style="text-align: justify;">6) One of the advantages cited for using a sump/submersible pump system is the sump acts as an extra reservoir for the system. The bottom trough of an 80′ long system holds about 300 gallons of water. A typical sump only holds about 30 gallons; really an insignificant amount. The main purpose of a sump area is to provide a place where a submersible pump can run in water so it doesn’t burn up.

We knew we could lower the cost if we reduced the number of people that handled a product, and in many cases improve the quality.</p> <p style="text-align: justify;">Replacement motors for fans and feed systems were the first items we started to direct source.  OEM Fan and feed auger companies do not produce their own motors; they all buy from the same motor companies.</p> <p style="text-align: justify;">We did not just buy off-the-shelf motors. We specified certain improvements in the motors based on our experience.  For instance, one problem according to our service department was motor shaft breakage.  We changed the shaft diameter blend radius and specified a hardened shaft of 1144 steel. We eliminated the problem.</p> <p style="text-align: justify;"><strong><em>Some people may have the perception that GrowerSELECT products are just cheap generic copies. How would you answer that?</em></strong></p> <p style="text-align: justify;">I am not going to tell anybody that we invented feed systems or fans. However, in almost every case we are able to look at existing products and make improvements.</p> <p style="text-align: justify;">We evaluate every item developed for the GrowerSELECT lineup in three different ways.</p> <p style="text-align: justify;"><span>First, from an engineering standpoint.</span></p> <p style="text-align: justify;">Can we make this product out of different material? Can we make it easier to manufacture?  Can we change the shape or size to eliminate problems?</p> <p style="text-align: justify;"><span>Second, we evaluate from a repair standpoint with feedback from our service departments.</span></p> <p style="text-align: justify;">What are you fixing out in the field?  Where is this product failing?  What would make the product easier to service?</p> <p style="text-align: justify;"><span>Third, and most importantly, we evaluate from our customer’s standpoint.</span></p> <p style="text-align: justify;">Is this the right product? Is this the right size?  What is giving you the biggest headache in using this product?   What changes would you make?</p> <p style="text-align: justify;">After gathering this information, we conduct the <strong>Process Failure Effect Mode Analysis or PFEMA</strong>.  Simply put, this is a logic method for determining why a product fails and how to correct it.  We document the process and can refer back to it when problems arise.</p> <p style="text-align: justify;">We then create detailed 3D computer models of the proposed product and subject it to computer-simulated stress tests.</p> <p style="text-align: justify;"><strong><em>Wait a minute; you can test the product before it is even built?</em></strong></p> <p><img class="alignleft size-medium wp-image-882" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/08/SowMAX-feed-hopper-blog-300x225.jpg" alt="SowMAX feed hopper blog" width="300" height="225" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">Yes, here’s a good example.  When we first designed the blue plastic hopper for the SowMAX, we did not have a lip at the top.  When tested via computer simulation, we realized it might crack when impacted, for example if a feed cart banged into it.  We added the lip to strengthen the hopper and eliminated a potential problem.</p> <p><img class="alignleft wp-image-883" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/08/ITM-HS524-IMG-300x231.jpg" alt="Grower Select clear upper boot" width="180" height="139" style="float: right; padding: 10px;" />Another example is the GrowerSELECT® clear upper boot, injected from impact-resistant polycarbonate.  It does not have to be as thick as plastic boots used by other manufacturers to have a superior breaking strength.  We were able to “tweak” the material thickness and avoid adding unnecessary additional cost to the end user.</p> <p style="text-align: justify;">The next part of the process is to send the drawings to a manufacturer and order sample parts to test against a quality control process known as <strong>PPAP or Production Part Approval Process</strong>.</p> <p style="text-align: justify;"><em><strong>Okay, what does that mean?</strong></em></p> <p style="text-align: justify;">It is the same quality control process the automobile supply industry uses.  It means we take the sample products and measure them against the drawings we created.  We particularly identify those measurements most critical to the quality of the product.</p> <p style="text-align: justify;">Once we are satisfied that the sample batch is correct, we then order a small production run.  This first-production run is then field tested.  Our service group installs them on farms, and we monitor the results.</p> <p style="text-align: justify;">After field-testing is completed, we release the product to manufacturing.</p> <p><img class="alignleft size-medium wp-image-884" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/08/Classic-Flood-QC-check-300x168.jpg" alt="Classic Flood QC check" width="300" height="168" style="float: left; padding: 10px;" />Before receiving those released products into warehousing, our Quality Control department conducts a series of QC checks.  Keith Riley, QC department head, creates an <strong>Incoming Inspection Document</strong> for each item.  This establishes a benchmark of quality checks used to test production parts.  This is not only done the first time we receive the product, but every time that product arrives from the manufacturer. </p> <p style="text-align: justify;"><strong><em>How many people work in Hog Slat’s engineering department?</em></strong></p> <p><img class="alignleft size-medium wp-image-885" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/08/Tim-Timblog-300x200.jpg" alt="Tim &amp; Tim,blog" width="300" height="200" style="float: right; padding: 10px;" /></p> <p style="text-align: justify;">We have nine engineers and six Quality Control members. We have a good core of experienced engineers with several younger guys that we have hired…I like to say we have just the right blend of “gray hair” in the group. I have to say the younger guys have a great “toolbox” they bring with them. They are contributing with new technology.  A good example is the 3D printer we recently added to the department.  It is allowing us to perform some things we had not been able to do before.</p> <p style="text-align: justify;"><strong><em>What are future goals for your group?</em></strong></p> <p style="text-align: justify;">Continuous improvement of products.  <strong>Just because we have a product developed doesn’t mean we quit trying to make it better. </strong> We think we can improve motors. One of the principle reasons we are able to offer a two-year warranty is that we have such a very small percentage of motors returned under that warranty. But, we have some ideas that will improve these motors even more.</p> <p><img class="alignleft size-medium wp-image-892" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/08/SupplyChain-300x300.jpg" alt="Hog Slat Supply Chain" width="300" height="300" style="float: left; padding: 10px;" />Hog Slat has a very unique position in the industry.  We are responsible directly to the end user.  It is our own people installing and servicing the products we sell.  We cannot pass off problems to someone in the supply chain; we are the entire supply chain to the end user.</p> <p style="text-align: justify;">We have access to company farms to test new products.  We have feedback from our own service crews.  Our goal is to use these resources to improve product offerings and get those improvements to the market faster.</p> <p style="text-align: justify;"><b></b>One of things I think we are the best at is <strong>identifying the optimum place in the world to manufacture a product.</strong>  We are not just throwing everything to Southeast Asia.  In fact, we have moved several products back to the United States. A good example is Classic Flood feeders, we started overseas but now these parts are molded in the U.S.</p> <p style="text-align: justify;"><b></b>We do a lot of final assembly at our locations in Clinton, NC and Humboldt, IA.  We source items from the U.S. and other parts of the globe, bring those components in to test, then assemble the end products.  Using this process we have more control over the quality of the final product.</p>urn:store:1:blog:post:20https://hogslat.ca/grower-select-curtain-machine-2Grower Select Curtain Machine<p style="text-align: justify;">In our blog post highlighting Hog Slat’s engineering department (see <a href="http://www.hogslat.ca/engineering-grower-select/">Engineering Grower Select</a>) Frank remarked, “In almost every case we can look at existing products and make improvements.”</p> <p style="text-align: justify;">The GrowerSELECT® Curtain Machine is a great example of making changes to existing products to improve performance and reduce maintenance.</p> <p><img class="alignleft wp-image-1000" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/09/curtain-machine-keyhole-204x300.jpg" alt="curtain machine keyhole" width="122" height="180" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">If you have ever “hung” a curtain machine, you will appreciate this feature. After placing a lag bolt in the wall about ½” short of flush, you simply hang the machine from a single keyhole slot in the back of the cabinet. It is much easier to level and add the four mounting lag bolts because the unit remains supported. </p> <p><img class="alignleft wp-image-1001" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/09/Curtain-machine-top-300x256.jpg" alt="Curtain machine top" width="210" height="179" style="float: right; padding: 10px;" /></p> <p style="text-align: justify;">The Curtain Machine includes three sealed ball bearing head pulleys instead of two.  The extra pulley is added to increase the choices for installing the main cables.  Use the two outside pulleys to cable the machine on both sides of the building.  Single-sided installations have the off side cable routed through the top pulley.</p> <p><img class="alignleft wp-image-1002" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/09/Curtain-machine-drive-block-300x200.jpg" alt="Curtain machine drive block" width="240" height="160" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">One of the highest mortality items on a screw type machine is the load block.  Other curtain machines use bronze, brass or nylon. However, the GrowerSELECT machine utilizes a self-lubricating, low friction acetal plastic for both the insert nut and load block slides.   For a more in-depth comparison see our blog post, <a href="http://www.hogslat.ca/more-than-you-ever-wanted-to-know-about-curtain-machine-load-blocks/">“More Than You Ever Wanted to Know about Curtain Machine Load Blocks.”</a></p> <p><img class="alignleft wp-image-1003" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/09/Curtain-machine-Aux-switch-300x244.jpg" alt="Curtain machine Aux switch" width="240" height="195" style="float: right; padding: 10px;" /></p> <p style="text-align: justify;">The Curtain Machine features dual limit switches.  The primary limit switches set the travel length, with secondary or redundant switches backing these up. If the first switch fails and engages the secondary switch, the machine shuts down and must be serviced before operating again.  Also included is an auxiliary switch, used to activate a fan after the curtain closes.  Other brands charge extra for this feature.</p> <p><img class="alignleft wp-image-1004" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/09/Curtain-machine-switches-300x200.jpg" alt="Curtain machine switches" width="240" height="160" style="float: left; padding: 10px;" /></p> <p style="text-align: justify;">Another feature you will appreciate is the local control switches, standard with the GrowerSELECT Curtain Machine.   A toggle switch sets the machine in manual and overrides the ventilation control.  This is a great safety feature that prevents anyone from activating the unit while it is being serviced.  In addition, it certainly makes it easier to set the limit switches compared to performing this task from a remote controller.</p> <p><img class="alignleft size-medium wp-image-1007" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/09/GS-Curtain-machine-close-up-mounted_edited-1-125x300.jpg" alt="GS Curtain machine close up mounted_edited-1" width="125" height="300" style="float: right; padding: 10px;" /></p> <p style="text-align: justify;">Eventually, any curtain machine will have to be serviced, and this is where the GrowerSELECT Curtain Machine shines.  Note the cutouts in the galvanized housing. You can slip the entire motor assembly out of these slots after loosening three mounting bolts.  It is much easier to service the motor outside of the cabinet.</p> <p style="text-align: justify;">The entire screw assembly will also come out through these cabinet slots.  It’s still a big job, but it’s possible to slide the entire assembly out for servicing rather than dismantling the screw inside the cabinet.</p> <p style="text-align: justify;">Although not groundbreaking, the GrowerSELECT Curtain Machine is an example of Hog Slat’s commitment to engineering better products.</p>urn:store:1:blog:post:19https://hogslat.ca/more-than-you-ever-wanted-to-know-about-curtain-machine-load-blocksMore Than You Ever Wanted to Know about Curtain Machine Load Blocks<p><img class="aligncenter size-large wp-image-1169" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/09/GS-Load-Blocks-1024x442.jpg" alt="Image of curtain machine load blocks on a table" width="690" height="297" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">Nearly all of Hog Slat’s competitors try to dismiss the GrowerSELECT® product line as “just a cheap copy.” However, every time I work with Hog Slat’s engineering department I realize how misguided this perception is.  Nothing is ever “just copied.”</p> <p style="text-align: justify;">I was quizzing Hog Slat engineer, Tim King, about the features and benefits of GrowerSELECT’s Curtain Machine.   He explained to me that one of the highest replacement items on a screw type machine is the load nut. As the load block moves up and down the Acme screw, the friction generated causes the insert to fail.  If friction is reduced, wear and maintenance of the insert is reduced.</p> <div id="attachment_1171" class="wp-caption alignleft"><img class="size-medium wp-image-1171 " src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/09/GS-Load-Block-Compare-300x129.jpg" alt="Curtain Machine loads block compared" width="300" height="129" style="display: block; margin-left: auto; margin-right: auto;" /> <p class="wp-caption-text" style="text-align: center;">1. Grower Select – Aluminum Block/Acetal Insert<br />2. Brass Block<br />3. Aluminum Block/ Brass Insert<br />4. Steel Block/ Nylon Insert</p> </div> <p style="text-align: justify;">For the GrowerSELECT Curtain Machine, Tim selected acetal plastic to be used for the insert and cabinet slides.  Acetal is one of the strongest non-reinforced plastic available to replace metal bushings.  It is able to reduce friction within the curtain machine because of its low friction coefficient.  So why is this plastic a better choice than the brass or nylon inserts shown in the pictures?</p> <p style="text-align: justify;">To get a better understanding of <b>Coefficients of Friction</b>, consider these ratings of various materials used for bearings.</p> <p style="text-align: justify;">Steel on steel dry contact is<b> .80, </b>if you apply grease it becomes <b>.16</b></p> <p style="text-align: justify;">Brass on steel dry contact is <b>.35</b>, grease it and it is now <b>.19</b></p> <p style="text-align: justify;">Nylon on steel dry contact is .<b>25</b> and with lubrication moves to .<b>15</b></p> <p style="text-align: justify;">Acetal on steel dry rating is .<b>15</b>.</p> <div id="attachment_1165" class="wp-caption alignleft"><img class="size-medium wp-image-1165" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/09/GS-insert-300x294.jpg" alt="Curtain Machine inserts" width="300" height="294" style="display: block; margin-left: auto; margin-right: auto;" /> <p class="wp-caption-text" style="text-align: center;">1. Nylon<br />2. Grower Select Acetal<br />3. Brass block<br />4. Brass insert</p> </div> <p style="text-align: justify;">These ratings aren’t telling anyone anything they didn’t already know. Keep a bearing greased, and it will last a long time. What is interesting though is the rating for an acetal load nut without grease is the same as any of other insert materials with grease.</p> <p style="text-align: justify;">As a matter of fact, the acetal load nut does not even have a grease zerk.  However, we still recommend greasing the Acme shaft with general purpose Lithium grease, primarily to prevent surface rust on the shaft.</p> <p style="text-align: justify;">I wish you could put your hands on the four inserts in the picture.  The acetal has a slippery, almost oily feel to it; different than the nylon insert.  It is a denser, heavier plastic that is less brittle compared to nylon.</p> <p style="text-align: justify;">The real advantage is in the day-to-day maintenance on your farm.  The best intentions (like greasing a curtain machine) get lost in the bustle of all the work.  Why not choose a curtain machine with features that reduce maintenance?</p>urn:store:1:blog:post:18https://hogslat.ca/changing-fan-v-beltsChanging Fan V-belts<p style="text-align: justify;">Just saw some interesting info from Billy Farmer. Billy is the store supervisor in Georgia, and had just attended the 2012 Poultry Tunnel Ventilation Workshop at the University of Georgia. They always put out great technical informational at their workshops and this piece caught my eye.  We all know that we should change v-belts on belt drive fans when they get worn but….why?</p> <p style="text-align: justify;">V-belts don’t actually stretch as is commonly referred. They get thinner as they wear. Because they get thinner, the belts will start to ride lower in the pulley groove. When this happens it’s just like the pulley becoming smaller. As the fan spins slower it moves less air. CFM delivery is directly proportional to the fan speed. Spin the fan 10% slower and it moves 10% less air. Reducing the CFM capacity of a building by 10% can spell disaster in terms of pig and broiler performance during the heat of the summer.</p> <p style="text-align: justify;">How do you know when to replace a V-belt? </p> <p><img class="alignleft size-full wp-image-468" title="v-belt" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2012/05/v-belt.png" alt="" width="173" height="128" style="float: left;" /></p> <p style="text-align: justify;">A quick visual check will determine if  a V-belt is worn and needs to be replaced. If the belt is riding above the pulley groove, it is doing its job. If the belt is bottomed out in the groove and/or riding below the top of the groove, it’s time to replace the V-belt.</p> <p style="text-align: justify;">While you have the V-belt off, you should take time to inspect to the pulley itself. A new pulley has a sharp V-shaped groove. A pulley that is more U-shaped is worn and needs to be replaced before you put on the new V-belt.</p> <p><img class="size-full wp-image-484 aligncenter" title="old pulley" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2012/05/old-pulley2.png" alt="" width="128" height="70" style="display: block; margin-left: auto; margin-right: auto;" /><br /><img class="aligncenter size-full wp-image-483" title="New pulley" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2012/05/New-pulley3.png" alt="" width="128" height="69" style="display: block; margin-left: auto; margin-right: auto;" /></p> <p style="text-align: justify;">To make the job of replacing V-belts less expensive, Hog Slat developed our own line of V-belts called GroBelts.

Measuring 10′ x 10′ x 28′ long, the Wind Tunnel was constructed according to AMCA standard 210 and installed at the Clinton, NC facility in May 2015.</p> <p>Fans to be tested are fixed in place on one end of the Wind Tunnel.</p> <div id="attachment_2540" class="wp-caption aligncenter"><img class="wp-image-2540 size-full" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2016/05/20-Hp-Forcing-Fanweb-e1464904259707.jpg" alt="Air Forcing fan powered by a 20 Hp motor" width="600" height="400" /> <p class="wp-caption-text">Air Forcing fan powered by a 20 HP motor</p> </div> <p>A 48″ axial vane fan, powered by a 20 hp motor, located on the opposite end of the tunnel, forces air into the chamber.</p> <div id="attachment_2541" class="wp-caption aligncenter"><img class="wp-image-2541 size-full" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2016/05/Nozzle-wall-web-e1464904284726.jpg" alt="Nozzle wall " width="600" height="400" /> <p class="wp-caption-text">Nozzle Wall</p> </div> <p>After passing through a series of mesh straighteners, the air is then forced through a nozzle wall consisting of metal cones that can be opened and closed to change available square inches of space.</p> <div id="attachment_2543" class="wp-caption aligncenter"><img class="wp-image-2543 size-full" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2016/05/Data-Transmittersweb-e1464904315317.jpg" alt="data transmitters feed " width="600" height="400" /> <p class="wp-caption-text">Pressure transmitters feed data to the automated recording system.</p> </div> <p> </p> <p>Two devices, called Differential Pressure Transmitters, measure and record the static pressure differential on each side of the nozzle wall.  To maintain precise accuracy, the transmitters are calibrated monthly and are also returned to the manufacturer for a factory re-calibration once per year.</p> <p>One of the key features of Hog Slat’s test chamber is the automated recording system that records data without any manual input from an operator. The Wind Tunnel is ramped up from zero to maximum static pressure while up to two data points per second are recorded in real time. This automated recording system is a custom program developed by a team from Hog Slat’s engineering group. This allows Wind Tunnel technician, Matt Parker, to supply the engineering group with a complete fan performance graph instead of limiting the information to only a few selected data points.</p> <div id="attachment_2578" class="wp-caption aligncenter"><img class="wp-image-2578 size-full" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2016/06/Matt-Display-screenweb-e1464904337753.jpg" alt="Technician Matt Parker views display screen readouts.

Every manufacturer, distributor, and dealer adds their own margin and the final cost includes these “stacked margins.”</p> <p> </p> <p>This type of distribution system has evolved over time and in many cases is the best method to deliver products efficiently to consumers.  The margins charged by these “middle men” aren’t evil or bad as long as they add value to a product through manufacturing, warehousing, installation or technical support.</p> <p> </p> <p>We would all agree that the structure of the poultry and hog industries has changed a great deal in the last 20 years, and some parts of the supply chain have changed along with it.  At one time, local dealers sold, mixed and delivered complete feed to production sites.  As producers became larger, they quickly moved to reduce the number of people involved in formulating and manufacturing feedstuffs and realized substantial cost savings.</p> <p> </p> <p>The supply chain to deliver feed systems and ventilation systems has not changed for decades.  Companies design and manufacture products, warehouse, finished goods and hire representatives to “set up” local dealer networks. The dealers provide a storefront, promote the brand locally, order and stock parts, hire salespeople and installation crews.  The industry is still delivering production equipment to the end user the same way it did when the number of producers was much larger.</p> <p> </p> <p> </p> <p><img class="alignleft size-medium wp-image-865" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2014/07/Grower-Select-2x6-R-small-300x88.jpg" alt="Grower Select 2x6 ®" width="300" height="88" style="float: left;" />Hog Slat developed the GrowerSELECT® line to collapse the supply chain, reduce margins and lower the final cost.  How?</p> <p> </p> <p>Hog Slat established a network of company stores in the major livestock and poultry production areas of the U.S.   This system was backed up with distribution centers totaling over 600,000 square feet. We control distribution costs and the margins charged against the final purchase price.</p> <p> </p> <p>The resulting volume of goods sold through our store system and large turnkey construction business enabled Hog Slat to justify the investment needed to manufacture feed and ventilation systems for our customers. We design and control the manufacturing process and the costs involved.</p> <p> </p> <p>Typically, manufacturing companies do not have retail systems in place to deliver, install and service systems on a local level. Local dealers do not have volumes large enough to hire engineers to design and manufacture products for their local markets.  Hog Slat is the only equipment supplier in the poultry and swine industries to integrate the supply chain vertically.</p> <p> </p> <p>If you have priced any GrowerSELECT equipment, you have probably been pleasantly surprised at the cost savings. You may have even hesitated to buy it because of the low price.   After all, “you only get what you pay for” is true. Buying products through the traditional distribution means you are paying the built in margin stack.  If you are ready to stop paying “margin stack” on feed and ventilation systems contact one of our local stores about GrowerSELECT, go online to www.hogslat.ca or call 519-348-8483.</p>urn:store:1:blog:post:15https://hogslat.ca/selecting-ag-replacement-motorsSelecting Ag Replacement Motors<div id="attachment_2674" class="wp-caption aligncenter"> <p class="wp-caption-text">Nameplate from GrowerSELECT fan motor</p> </div> <p>Today’s livestock and poultry operations rely on electric motors for a variety of feeding and ventilation functions. Used in buildings that can be both dusty and humid, with fluctuations in voltage and varying workloads we subject our motors to a very hostile work environment.</p> <p>When selecting replacement motors, it is important to select motors that are both efficient and designed with a “safety factor” that will allow them to last under harsh conditions.</p> <p>While you may be familiar with the term Service Factor or S.F., there are a couple of important designations found on a motor nameplate that may need more clarification.</p> <p>Service Factor is defined as a motor’s ability to operate under a short-term load.   The higher a motor’s S.F. rating, the more durable the motor.  Motors with high S.F. are expected to last longer. To illustrate, a 1-1/2 Hp motor with a 1.5 S.F. can provide 2.25 Hp for short-term use.   However, it is not a good practice to continuously operate a motor above the rated workload. In other words, the same 1-1/2 Hp motor with  1.5 SF would not be selected to power a 60″ fan originally shipped with a 2 Hp motor.</p> <p>Full Load Amps or F.L.A. represents the amount of current the motor is designed to draw at the rated horsepower. In the example nameplate, this means that when the motor is running under a full load at 230 volts, we can expect it to draw 5.4 amps. Motors with a lower F.L.A. for the amount of horsepower are considered more efficient to operate.</p> <p>Service Factor Amps or S.F.A. represents the amount of current the motor will draw when running at the full Service Factor. In the example nameplate, the S.F.A. is eight amps at 230 volts.</p> <p>Continually exceeding the S.F.A. shown on the nameplate can shorten motor life. Motors with a higher S.F.for the same horsepower have an increased “safety factor” and are expected to last longer under harsh conditions.</p> <p>The most efficient, rugged motors are designed with a higher S.F., lower F.L.A., and higher S.F.A ratings. By comparing the information on a motor nameplate, we can select the best replacement motors for feeding and ventilation equipment.</p> <p>Hog Slat designed the GrowerSELECT line of motors to help simplify a producer’s decision on selecting replacement motors. GrowerSELECT motors feature a high Service Factor (as high as 1.5) and higher  S.F.A. rating to increase motor life.  Each model number is a direct cross to the most popular brands of feed systems and fans used on producers’ farms. No matter what your existing brand of equipment we have a GrowerSELECT motor designed to replace it and save money while doing so.</p>urn:store:1:blog:post:14https://hogslat.ca/feed-system-checklist-for-hog-poultry-buildingsFeed System Checklist for Hog & Poultry Buildings<p>Most producers have a checklist for basic equipment repairs between groups to prevent costly and time-consuming problems later. One commonly overlooked item is the feed delivery system. Whether you choose to have the auger inspected by a service crew or do the work yourself, the following is a checklist of essential feed system maintenance items for producers to consider.</p> <p><strong>Remove the Feed</strong><br />The most important and basic procedure for auger maintenance is to empty all the feed from the system. Feed left in the auger tube will draw moisture and cause the auger flighting to rust.</p> <p><strong>Upper and Lower Boots</strong><br />The metal lower boots should be visually inspected for worn or rusted areas, bent slide gates and damaged access covers. GrowerSELECT® components can be used to replace individual items including body weldments for all flexible auger sizes.</p> <p>Grower Select clear upper boots can replace existing solid boots so potential problems with feed delivery are easier to spot.  Injected from impact-resistant transparent polycarbonate, GrowerSELECT boots will fit any 16” bin opening and are available in 30° or straight models.</p> <p><strong>Anchor Bearings</strong><br />Auger bearings are a high wear item and should be checked whenever they are squealing or rattling. To inspect the anchor bearing, loosen the U-bolts holding the bearing, pull the bearing out from the tube and clamp a vise grip on the auger to hold it in place. Inspect the anchor bearing for visible wear and excess play. If the bearing needs to be replaced, select a GrowerSELECT anchor bearing that matches the size and brand of your system.</p> <p><strong>Flexible Auger</strong><br />Auger that is more than ten years old or installed with multiple turns should be examined for wear. Examine the auger to look for sharp edges concentrating on the elbow areas. Also check the distance between the flighting making sure this distance has not been compacted or stretched. To remove the auger for inspection; detach the anchor bearing from the auger and allow the auger to retract inside the tube. Go up to the drive unit and open the inspection plate on the control unit. Loosen the hex head bolt on the clamp holding the auger to the tube anchor. Holding the auger solid, rotate the anchor counterclockwise until the auger is free. Go back to the boot area and pull the auger out the back end of the system.</p> <p>There are several options for repair.<br />A) Replace the entire auger.<br />B) Cut out and replace only the worn section.<br />C) Turn the auger end for end and replace. This will place the worn section of auger in a straight section of the tube instead of in an elbow section.</p> <p><span>Grow-Flex™ auger is available custom lengths that are cut to order.</span></p> <p><strong>Elbows</strong><br />Many (most?) 10-year auger systems have duct tape over small holes in the tube where the auger enters the barn. Now is the time to replace the high wearing elbow sections while the auger is removed from the system.</p> <p><strong>Gear Head Oil</strong><br />The oil in auger gear heads should be completely replaced every two years. Remove the bottom and side plugs allowing the oil to drain out of the gear head. Replace the bottom plug and refill with oil until it reaches the level of the side plug. Replace side oil plug. GrowerSELECT Gear Oil is specialty 80W-90 oil designed for use in any existing auger gear head.</p> <p><strong>Pinion Gears<br /></strong>It is also a good time for a visual inspection of the pinion gear connecting the motor shaft to the gear head. The teeth of the pinion should be sharply cut; pinions with rounded teeth should be replaced. There is a GrowerSELECT replacement pinion gear for most existing auger systems…</p> <p><strong>Feed Level Controls</strong><br />Faulty feed controls can cause feed outages or wastage when they malfunction. There are many options of GrowerSELECT feed level controls available for replacements. The HS529 is a direct replacement for feed level controls mounted in the feeders. The Proxy Plus (HS10) and the Proxy Classic (HS09) are GrowerSELECT replacements for existing proximity switches.<br />This may also be a great time to consider a complete change in feed control switches. The Grower Select Drop Tube Control Switch (HSDTC01) is an excellent option for controlling the feed system. This type of switch removes the electrical components from inside the feeders helping minimize switch failure due to electrical problems.</p> <p><strong>Feed Bins</strong><br />Older feed bins may have rusted areas or even pinholes in the exterior metal sheets. An excellent product to restore these areas and extend the bin’s useful life is AMC100L; an aluminum based coating that provides corrosion and weather protection. It is available in DIY kit form containing 1 quart of AMC100L, 1 pint of rust remover and 4 pieces of seam tape. This starter kit will cover 200-300 sq ft.</p> <p>Producers have also upgraded feed bins with a simple feed level indicator called the Bin Flag. This low-cost device (just over $100) allows operators to check bin feed levels without climbing. No wiring is required for operation and the installation is all done from the outside. The Bin Flag can also be connected to building alarm system for dialer notification of feed outages.</p> <p>Contact a local Hog Slat store to order feed system repair items. Hog Slat stores also have service crews available for on-farm repairs and inspections.</p>urn:store:1:blog:post:13https://hogslat.ca/growerselectchange-the-way-you-buyGrowerSELECT…Change the Way You Buy<div id="attachment_2178" class="wp-caption aligncenter"> <p class="wp-caption-text">Broiler houses at a Georgia farm.</p> </div> <p>When it comes down to it, the cost of manufacturing a high-quality product is the same for most companies producing equipment for the livestock and poultry markets. Most companies have identified the most efficient methods to build an anchor bearing, motor, feeder, nipple waterers, etc.</p> <p> </p> <p>The real cost difference comes from the delivery of those products to the end user. The standard model of distribution, in our industry, involves a manufacturer producing a product line, warehousing it, and employing a sales force to establish a dealer network.</p> <p> </p> <p>The dealer network stocks the equipment, maintains a storefront, hires salespeople, installs, and services the production systems in a local area for the brand of equipment they represent.</p> <br /> <p></p> <p>This particular type of distribution model has changed very little over the history of the livestock and poultry production industries. Each member of this distribution model is an independent business entity and is free to add whatever margins they deem necessary (or possible) to the final cost a producer pays.</p> <div id="attachment_2179" class="wp-caption alignleft"><img class="wp-image-2179 size-medium" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2016/01/SupplyChain_web-300x300.jpg" alt="GrowerSELECT supply chain removes extra dealer margins to producer." width="300" height="300" /> <p class="wp-caption-text">GrowerSELECT supply chain removes extra margins to reduce the final cost to end users.</p> </div> <p> </p> <p> </p> <p>Sold through a different type of distribution model, GrowerSELECT goes directly to livestock and poultry growers through our network of regional local stores. Because we own the distribution chain from top to bottom, we add only ONE MARKUP over our cost.</p> <p> </p> <p>Our cost is based on finished goods plus ONE MARKUP vs. MULTIPLE MARKUPS from the typical distribution model.</p> <br /> <p></p> <p></p> <p>Also, we would suggest that we are the low-cost producer for most products. Wait a minute; the first paragraph said the cost of manufacturing was the same for everyone.</p> <p> </p> <p>True. But if a brand has a loyal dealer network, the pricing to the dealer network will not be challenged. A loyal dealer will continue to buy brand name products even if the cost is excessive.</p> <p> </p> <div id="attachment_2181" class="wp-caption alignleft"><img class="wp-image-2181 size-full" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2016/01/GS-Auger-motor-web-e1452883793178.jpg" alt="GrowerSELECT auger motor with 2 year warranty. " width="326" height="292" /> <p class="wp-caption-text">GrowerSELECT auger motor with 2-year warranty.</p> </div> <p>Name brand motors are a perfect example of this. An auger or fan company buys a motor from a motor manufacturer, puts their logo on it and sells it to a local supplier. The local supplier sells the motor to the end user adding little value to the final price. A local supplier has few other options. Their volume of a particular motor isn’t high enough to go directly to a motor manufacturer, and they have little negotiating power with their chosen brand vendor. The brand company has little incentive to lower the cost to a loyal dealer network. In fact, a brand company can charge different prices in different geographical locations depending on market pressure.</p> <p> </p> <p> </p> <p>Compare this with GrowerSELECT motors. Our network of over 70 store locations and turnkey construction business allows for large purchases of motors direct from a manufacturer. We forecast purchase amounts for each store location and ship directly with minimal warehousing cost. Local retail pricing continually drives us to buy at a more competitive price.</p> <p> </p> <p>The conventional distribution chain is directed from the TOP DOWN versus the GrowerSELECT model which is driven from the BOTTOM UP. Lower pricing for comparable products is the result.</p> <p> </p> <p>The GrowerSELECT distribution model also affects product responsibility. Because we interact directly with the end users, we deal directly with any problems arising with the installed products. We sell it; we service it, and the end user works with one company.</p> <p> </p> <p>The traditional marketing chain allows room for some question regarding who is responsible for dealing with equipment failures when those problems arise. The manufacturer can blame poor installation, dealer system design, or a number of other reasons (excuses) for a product’s failure. A local supplier can blame the brand company for poor design or manufacturing flaws. The GrowerSELECT distribution system eliminates “finger pointing” and focuses on providing accountability to each and every customer.</p> <p><img class="alignleft wp-image-2183 size-full" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2016/01/gold-coins-on-calculator-with-GS-logo1-e1452883851672.jpg" alt="gold-coins-on-calculator-with-GS-logo" width="450" height="300" />Our customers produce commodities.

Rust causes steel to thin over time, reducing its strength and causing product failure.</p> <p style="text-align: center;"><img class="wp-image-2837" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2017/01/rust_surface770x400-e1485958424408.jpg" alt="Paint coating protect steel from elements until damaged." width="600" height="253" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Paint coating protects steel from elements until damaged.</em></p> <p style="text-align: justify;">Any coating, which provides a barrier to moisture and oxygen, protects steel from corrosion. A painted surface provides an effective barrier until it is broken allowing moisture and oxygen to come in contact with the steel beneath. Rust develops at the breakage point and can even extend under the protective paint barrier.</p> <p style="text-align: center;"><img class="wp-image-2838" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2017/01/zinc-coating770x400-e1485958459893.jpg" alt="Galvanized coatings protect steel even when damaged." width="600" height="291" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Galvanized coatings protect steel even when damaged.</em></p> <p style="text-align: justify;">Similar to paint, a galvanized coating forms a protective barrier to protect steel from moisture and oxygen. Galvanized coatings also provide a second method of protecting steel by electrochemically "sacrificing" the zinc in the present of corrosive elements.   In other words, the zinc corrodes, until it is depleted, instead of the metal underneath. Because it is physically bonded to the metal, galvanized coating does not allow rust to extend beneath its surface.</p> <p style="text-align: center;"><img class="wp-image-2839" src="http://www.hogslat.com/images/uploaded/wp-content/uploads/2017/01/Galvanized-Layer770x400-e1485958497865.jpg" alt="Heavier G100 galvanized coatings offer 10% longer service life. " width="600" height="312" style="display: block; margin-left: auto; margin-right: auto;" /> <em>Heavier G100 galvanized coatings offer 10% longer service life.</em></p> <p style="text-align: justify;">Galvanized coatings are expressed in ounces per square ft with conventional coatings designated as G30, G40, G60, and G90. These refer to thickness of .30, .40, .60 and 90 oz./ft<sup>2</sup>, respectively. Corrosion resistance is directly proportionate to the amount of zinc coating on the steel. Therefore we would expect the service life of G90 steel to be roughly three times that of G30 in the same environment. Likewise, increasing the galvanized coating on a feed bin from G90 to G100 increases the bin's service life by 10%.</p> <p style="text-align: justify;">Galvanized steel is an excellent choice for use in feed bin fabrication, as it does not degrade when exposed to the sun's ultraviolet rays like painted coatings or poly bins.</p> <p style="text-align: justify;">In addition to heavier galvanized coatings, Hog Slat bins are manufactured from stronger Grade 55 steel, come with an improved ladder design and water deflecting Weather Edge™.

"The emphasis is on using corrosion resistant materials to reduce maintenance and delivering energy efficient air flow at typical operating static pressures.”  </p> <p style="text-align: justify;">The new X-Brace fan series consists of a through-wall mount 54" fan and an exterior mount 57" panel fan. Composite fiberglass housings and poly discharge cones provide both models with excellent corrosion protection. A flush mount kit is also available for the 57” adapting it to through-wall installations.</p> <p style="text-align: justify;"><img width="650" height="338" class="aligncenter size-full wp-image-3014" style="display: block; margin-left: auto; margin-right: auto;" alt="X-Brace-Mounting-770x400" src="/images/uploaded/blog/Airstorm-xbrace/X-Brace-Mounting-770x400-e1499974789650.jpg" /></p> <p style="text-align: justify;"><strong>Rigid X-Brace support</strong></p> <p style="text-align: justify;">The fan series gets its name from an innovative X design which moves the anchor points of the support arms to the housing corners for maximum stability.   The support arms are manufactured from aluminum tube with a blue epoxy coating for increased corrosion protection and incorporate a triangular edge profile to reduce wind turbulence. Rubber corner mounts cushion the fiberglass housing from vibrations. The stainless steel support plates for the motor and bearing assembly bolt to the X-Brace with stainless steel hardware.</p> <p style="text-align: justify;"><img width="650" height="338" class="aligncenter size-full wp-image-3016" style="display: block; margin-left: auto; margin-right: auto;" alt="X-Brace Pillow-Block-770x400" src="/images/uploaded/blog/Airstorm-xbrace/X-Brace-Pillow-Block-770x400-e1499978219504.jpg" /> <strong></strong></p> <p style="text-align: justify;"><strong>Improved bearing life</strong></p> <p style="text-align: justify;">A new solid base bearing housing allows a more stable mounting to reduce vibration significantly.

"The performance curve is very flat with these fans," explained Hog Slat's ventilation director, Austin Baker. "The prop's most efficient cfm ratings are delivered at standard house operating pressures of between .05 and .15". <img width="650" height="338" class="aligncenter size-full wp-image-3015" style="display: block; margin-left: auto; margin-right: auto;" alt="X-Brace-Butterfly" src="/images/uploaded/blog/Airstorm-xbrace/X-Brace-Butterfly-e1499978106757.jpg" /></p> <p style="text-align: justify;"><strong>Low maintenance shutters</strong></p> <p style="text-align: justify;">While the 54" fan uses a plastic interior shutter, the 57" model utilizes a poly butterfly damper with stainless steel hardware.

These opposing properties are why the two materials are used together when producing concrete products.  Embedding reinforcing steel in the concrete increases its ability to resist failure from tensile stress.</p> <p> </p> <p>Concrete slats are cast with steel bars placed at the top and bottom of the slats.  The top bars protect the slat from cracking while the slat is being transported and set in place.  After the slat is in place, the lower bar keeps the slat from cracking on the bottom.</p> <p><strong><img width="950" height="450" alt="WWR" src="/images/uploaded/Blog/Slat U_ Reinforcing Steel/WWR_950x450.jpg" /></strong></p> <p></p> <p><strong>Welded Wire Mats have several advantages over rebar for slat production</strong></p> <p> </p> <p>While rebar is the most common type of reinforcing steel used in poured-in-place concrete, welded wire reinforcement mats offer some distinct advantages when used in the production of concrete slats.   Fabrication of WWR mats consists of welding steel rods into large sheets specific to each slat mold.</p> <p> </p> <p>1) WWR mats are made from high tensile 80,000-psi steel wire formed by special equipment to the proper diameter and straightened.  In comparison, rebar has a lower 60,000-psi rating.</p> <p> </p> <p>2) By welding them into a mat, the rods do not move when concrete is placed, ensuring each bar is in its proper position.</p> <p> </p> <p>3) Automated equipment located in a controlled environment prefabricates the WWR mats lowering the risk of improper welds that can affect the strength of the steel.</p> <p> </p> <p>In general, using Welded Wire Reinforcement mats in the manufacturing of precast concrete slats yields a much more consistent product than production using individually placed rebar. </p> <p> </p>urn:store:1:blog:post:2https://hogslat.ca/slat-university-101-waterSlat U.101 - Water<p><strong>Slat University is a series of articles providing useful information on manufacturing, handling and maintaining concrete slats.</strong></p> <p><strong><span>Water: Most crucial component in a precast concrete mix.</span></strong></p> <p><strong> </strong></p> <p>Anybody who has ever poured concrete is familiar with the adage "the less water you use, the stronger the concrete will be." </p> <p> </p> <p>Here's why.</p> <p><img width="900" height="450" alt="water_cement" src="/images/uploaded/Blog/Slat U_101.Water/Water-Cement-Ratio-Image-900x450.jpg" /><strong>Excess water evaporates leaving behind large voids weakening the final product.</strong></p> <p>Water added to the dry ingredients begins a chemical reaction with the cement powder known as hydration, which bonds the aggregates together, creating the synthetic rock known as concrete. Any additional water added, beyond that needed for hydration, only creates larger spaces between the aggregates in the mix. These voids cause the concrete to be weaker and more porous.</p> <p> <img width="900" height="450" alt="slump cones" src="/images/uploaded/Blog/Slat U_101.Water/slump-cones_900x450.jpg" /></p> <p></p> <p><strong> Every additional inch of slump decreases the final strength by approximately 500 psi.</strong></p> <p> </p> <p>Concrete formulated with a minimal amount of water is known as dry-cast concrete.  To put this is in more familiar terms, dry- cast concrete exhibits a slump of less than a 1/4-inch.   Ready-mix concrete is typically formulated to have a four-inch slump. As a general rule, every additional inch of slump decreases strength by approximately 500 pounds per square inch. So for example, if a dry cast mix is designed to be 6000 psi, adding water to make it a four-inch slump could reduce the strength of the final product by as much as 2000 psi.</p> <p> </p> <p>Also, a dry cast product is also denser with fewer voids. As the excess water evaporates from the concrete with a higher water-cement ratio, microscopic pores are left behind.  These pores allow acids from hog waste and feed ingredients to migrate into the concrete, causing faster deterioration of the slat.</p> <p> </p> <p>If less water makes the best concrete why would any slat manufacturer ever add extra water?</p> <p> </p> <p><img width="900" height="450" alt="rotoscreen" src="/images/uploaded/Blog/Slat U_101.Water/rotoscreed_900x450.jpg" /> </p> <p>P<strong>owerful rotoscreeds trowel dry cast concrete.</strong></p> <p> </p> <p>Dry cast concrete is very difficult to handle without mechanized equipment.  Many manufacturers lack the equipment and know-how needed to place and finish dry cast mixes properly.  Water is added to the concrete mix so it flows into the molds and can be troweled.  While this may lead to manufacturing slats with a smoother physical appearance, the finished product will not be as durable or long-lasting as a dry cast slat.</p> <p> </p> <p>Also, some manufacturers may not have the technology to batch dry cast formulations consistently. To properly make dry cast concrete it is necessary to use state of the art batching equipment that measures the amount of moisture in the sand and aggregates and adjusts the amounts of these ingredients as well as the added water. These adjustments ensure that the final mix is always the same and doesn't vary during wet or dry weather. </p> <p> </p>urn:store:1:blog:post:1https://hogslat.ca/you-cant-afford-a-cheap-motorYou can’t afford a cheap motor<p><strong> </strong> </p> <p>Replacing motors on feed systems and ventilation fans is maintenance cost familiar to all hog and poultry growers. Many equipment retailers offer generic units as an option to more expensive Original Equipment Manufacturer (OEM) motors. At first glance, these motors may look comparable in horsepower, frame type, and mounting.</p> <p> </p> <p>Fan and feeding equipment manufacturers work with motor companies to source motors designed to match up with specific equipment. Generic motors, on the other hand, are stock items that motor manufacturers keep on the shelf to fit a wide variety of applications.<span>   </span>Although the quality of these stock motors can be good, they are not explicitly made for a single purpose.<span>   </span>While they will undoubtedly operate a feed system or ventilation fan, generic motors will typically not last as long or run as efficiently.<span>   </span>A closer look at the motor plate will give the information needed to make an informed choice.</p> <p> </p> <p>Here are two motor plates for two one horsepower direct drive auger motors to illustrate the difference.</p> <p></p> <p><img width="600" alt="GS motor plate" src="/images/uploaded/Blog/cheap-motor/GrowerSELECT.jpg" /></p> <p> </p> <p> <img width="600" alt="Generic motot" src="/images/uploaded/Blog/cheap-motor/Generic.jpg" /></p> <p> </p> <p><strong>Service Factor</strong></p> <p>S.F. or Service Factor is defined as a motor's ability to operate under an increased short-term load.<span>  </span>The higher a motor’s rating, the more durable the motor. In this example, the motor with 1.3 S.F. will provide additional horsepower when the motor is overloaded. Fluctuating voltage, common with rural power grids, can cause motor overloading even under normal system loads.</p> <p> </p> <p><strong>Amp draw</strong></p> <p>F.L.A. or Full Load Amps represents the amount of current the motor is designed to draw at the rated horsepower. In this case, the generic motor draws 6.4 amps while the GrowerSELECT motor is rated at 4.4 amps. We can estimate the annual electric usage by using the national average of 10¢ per kilowatt and the average run time of two hours per day.</p> <p> </p> <p>(6.4 - 4.4) amps x 230 volts = 460 watts</p> <p>460 watts x 2 hours/day x 365 days = 335,800 watts/year</p> <p>335,800 watts / 1000 watts = 335.8 kilowatts/year</p> <p>335 Kw x .10/ Kw = $33.58 difference in annual operating costs</p> <p> </p> <p>Please note that this example is a comparison of nameplate ratings only.<span>  </span>Actual application results will vary slightly depending on the specific application loading.</p> <p> </p> <p><strong>Weight</strong></p> <p>A straightforward item to check is the total weight of the motor.<span>  </span>Although not listed on the motor plate, the generic motor weighted 33 pounds while the GrowerSELECT weighted over 35 pounds.<span>   </span>A heavier motor tends to indicate more copper and steel are used in the windings. Heavier windings minimize heat buildup and dissipate the heat quicker.   Excessive heat is one of the primary causes of electric motor failure. In fact, for every 18 to 20 degrees increase in temperature, the expected motor life is cut in half. Other contributing factors to shortened motor life are related to component durability; such as aluminum wire usage, nondurable centrifugal switches along with less expensive start and run capacitors.</p> <p></p> <p> </p>
