The DeSite SLG portable vibratory screeners are proving to be a very popular item with contractors, cities, guys that are recycling and reclaiming. Just the basic investment costs and the productivity of these screeners have become an alternative to the guys that used to own the bigger screening plants. What they were finding was the investment they had in those machines, $25,000 to over $100,000, wasn’t warranted for the amount they were screening each year. With the DeSite screeners and their ability to anywhere from 20 to 60 yards per hour of material, at the price point, are so versatile, low maintenance and that low investment costs has made them very attractive to guys that are buying a screener for the first time or that have owned a large screener in the past and are looking for a screener that is a more productive and most cost effective.
DeSite SLG portable vibratory screeners are proving to be the screening alternative to the large expensive screeners that are out there that range in price from 25 to 50, 100 and even 100+ thousands of dollars. We get a lot of our customers buying these machines that have owned large machines in the past. They have too much money tied up into large expensive machines or the repairs are too high or are just not using them enough to warrant having those large machines around. The SLG machines are small and compact and they are absolutely affordable. They are giving guys screening independence who are looking for anywhere from 15 to 60 yards per hour in production. One thing to consider is that DeSite machines have very little depreciation. This screener, the 108VFRB, it would depreciate 1200 to 1500 dollar per year over the course of a lifetime of this machine. If you are looking to purchase a 100,000 dollar screener you can figure on 15,000 to 20,000 dollars per year depreciation the first year and half of that each year after. You’d have to screen an awful lot of material just to recuperate the depreciation. We’ve got guys that have owned DeSite machines for 2-3 years and come back and buy another new machine and they’ve only lost 2-3 thousand dollars in depreciation on a 12 to 13 thousand dollar investment. You can see they fit that need for guys that are looking for screening independence and just don’t want to tie up a lot of capitol. They’d rather spend their money on upgrading their excavators, loaders, dump trucks, that kind of stuff. Most of the screening occurs early in the spring, through the summer and into fall so having a really expensive machine around on the job for the months you’re not using it just doesn’t pay for guys. DeSite screeners are proving to be the alternative to large expensive machine for guys that are looking for screening independence without spending a lot of money.
This video is about the vulcanized 10 gauge 25-foot cord that you can purchase with this machine. It is twist lock on one end. The other end is three pronged. It is 110-volt cord. It is designed with a three prong on the other end so if you want to plug it into another 10 gauge cord you can get out one hundred feet with a 5000-watt generator. It is out away from the dust so you don’t have a lot of issues. This end is a twist lock, basically you take the cord, plug it into the bottom of the screener, turn it to the right. Then you have 25 foot of cord to power the screener up. I’m just going to take it over and plug it into the wall. We don’t put a start and stop switch on the screener because it is just not necessary and it’s just another thing you’d have to service down the road or possibly repair. We focus on keeping these machines as simple and durable as possible. I’m plugging it into a wall circuit. Hear the machine fire up. You can hear the dual eccentrics motors of the machine running.
The SLG108 machine has a duplex coil system on it that allows the screen deck to rock back and forth and change degree slope as your feeding that screener. When your feeding it with a big machine you’ll be able to pull that screen deck back, flatten that slope so as the material is traveling out of your bucket it is on a lesser slope. When you leave it will stand back up and shed that oversized material. In just a minute I’ll pull that screen deck back and forth so you can see the action of that screen deck jumping up and down and the advantage of being able to manipulate that deck slope while staying in your machine. The SLG screeners are one of the only screeners, in fact they are the only screeners out there on the market that allows the operator to manipulate the deck slope while they are feeding it. That’s really important because as you get into changing conditions and different types of products, be it sand, soil, compost, rock, it all travels at a different speed over the screen deck so you want to be able to manipulate that slope to keep that material moving fast or slow depending on the conditions your screening in.
The DeSite SLG108VFRB tilting screen deck can be moved by the operator staying in the machine. The machine’s bucket presses down on the top back to tilt the screen deck.
The DeSite SLG108VFRB can be moved in tight space with a fork lift using the built in fork lift pockets.
The Feed Deflector system on the DeSite 108VFRB. The feed deflector system is the black part on the top of the machine. It servers a couple of purposes. The main purpose is to funnel material and guide it to the top of the screen deck to start the screening process. The distance from the top of the screen deck to the leading edge of the feed deflector is 42 inches. That is done to accommodate buckets up to 36 inches wide. For example, if you have an excavator and your sitting at the side of the screener and your wanting to digging, spinning, and then dumping across the screen deck, that 42 inch opening catches that material and funnels it to the top to begin the screening process. The other part of that is, if your feeding it with a wheel loader, you have that feed deflector that has a rubber belt all the across the face of it. We do that in rubber so that material doesn’t stick to it. If it was made of steel, stuff would stick to it, it would freeze to it. Doing it in rubber keeps the material moving all the time. If you come in with a wheel loader, you can literally dump and as the material is falling forwards out of the bucket it will hit the feed deflector, it funnels the material back again to the top of the screen deck so that you are getting to use the whole screen deck during the screening process. As the material is dumping you take advantage of the whole 6 feet of deck, 10 feet wide. The other feature on this machine is that at times you will get large oversize debris in your bucket be it a stump or a big block or big stone or rock, 20 inches round, this feed deflector needs to be able to open up. We designed this to do is that it sits on a two-inch-wide casted lug down here that allows this feed deflector to pivot on. We have two retention changes on each side so it doesn’t open up to far. This feed deflector the way it is right now will open up 36 inches. Even if you get a very large piece of debris in there you have the ability to open that up and let it flow through rather than climbing up into the feeder, wrap a chain or a strap around it and trying to lift it out that way. We do a little cheat thing here. There is a 1 ½ inch strap on the front of the feed deflector that’s hanging. It serves two purposes. One is when you are wanting to change the screen mesh the feed deflector must open up all the way to expose all the bolts that go up the side of the screen deck. It makes it very easy to change the mesh out. The other is, say if you’ve got a big stump that is 36 inches or something like that, that is really large, you have the ability to come around and connect the strap to your machine and literally pull this feed deflector open until the retention chains get tight and that will create an opening that is 36 inches plus that will let that oversized material crawl underneath it and fall out on the ground. It’s all about not having to get the operator out of their machine to climb up into the feeder and throw something out, but having that ability to get the feeder to open up and let the large material pass thru. When we designed this on this quick change lug it is open on one side. The reason for that is we wanted the operator, say if they were screening some demolition debris, say they had knocked a house down or a warehouse had burned down and they had excavated the area, they’ll end up with a lot of dirt debris mixed in with the construction debris. Lots of time people are wanting to separate out that dirt to reduce the weight, so the dump costs are a lot less. On this 108 machine, you literally have the ability of disconnecting the retention chains and then lifting the feed deflector off and setting it to the side. What that creates then is one big open vibrating grizzly, 10 feet wide, 6 feet long. You can put up to a 4-inch mesh on this unit, which creates a 3-inch minus, if you had a burnt house that all the material was in a pile, you pour it over the screener, screens everything out, 3 inches and less, or 2 inches or less if you want to use a smaller mesh or an inch and less with an even smaller mesh, and that reduces a lot of the cost of the tip fees. Being able to use this with and without the feed deflector, very quick to take on and off, very easy to open, allows you the versatility and flexibility for this machine to be very productive out there on the job site.
The vibratory system on the DeSite SLG108VFRB. This screener has dual vibratory packs underneath it that turn at 3600 rpm deliver 760 pounds of force per motor. They are 110 volts, 60 hertz. For European customers power a 220 volt, 50 hertz system. The vibratory packs mount to the underside of the screen deck and are guarded by a 3/8-inch thick steel box that is fabricate to protect it and cover the motor. Then a 1/8-inch steel plate cover guards the underside of the motor. These motors have hydraulic lines going from motor to motor. We use these as a four wire braided hose for the electric wire to travel to the motors. Using a 4 braid wire hose give the flexibility for the deck to move, traveling back and forth, and while debris is falling through the screen deck the hose can move around and protect the wires inside. On the outside is where the control box is. Inside the control box are two starting capacitors, one for each motor. On the underside there is a twist lock plug. We offer a 10 gauge vulcanized plug that is a twist lock on one end and three prong on the other. Push the plug in on the bottom and turn it so it locks in place. The three prong end attaches to the extension cord. There are no starting switches because it is one more point for failure and maintenance. This is the simplest, lowest cost way to run this screener. The machine runs with a 5000-watt generator. You can be up to 100 feet away with a 10-gauge cord, allowing you to keep your generator away from the dust and the dirt, keeping the maintenance and your running costs lower. This is the 108 with the vibratory system, dual eccentric, 110 volts, 3600 rpm, 760 pounds of force.
This is a shot from the backside of the 108 topsoil screening machine by DeSite. I’d like to show you the suspension system. This is our new suspension for 2019. We changed the suspension actually works with our duplexed coil spring. There is a metal tube traveling inside the coil spring. There are nylon bushing at the top, middle and bottom that keep the coil from actually touching the tube. The amount of compression is doubled. It can sit at 45 degrees, lay a bucket on it, pull it all the way back to 25 degrees while you are feeding it and then it goes back to 45 degrees when you leave to shed any oversize material that is hung up on the screen deck. There is still a 3-piece spring pack. Those are duplexed, actually making 6 springs supporting the bottom of the spring deck. It’s like the springs in a truck. There is a spring with a rubber busing on the inside and the bolt that is going through it. The rubber busing helps isolate the vibrations to the screen deck and minimize the amount of vibration that travels down the side of the screener. There is a Z spring that sits on the bottom with a nylon busing. When the screen deck rocks back and forth the Z spring accepts that spring and accepts some of that load when the spring is coming back. Like our other past 108 machines we have kept the tilting system on the side of the screener. The whole plate and the suspension rotates on a hub that is on the side of the screener. To set the screener in a flatter fixed position loosen the bolts on the outer ring and then the spring deck will rotate backwards and forwards. Lock it in place at the desired angle. The 3/8 inch cut out stops acts as a stop telling you to stop rotating the screen deck either forwards or backwards. The stops are on both sides so the screen deck and the tension on the spring on time. It’s a simple system, very low maintenance. The only grease nipple on the entire suspensions is at the top of the spring at the top and again on the other side’s spring. All of the nylon bushing work dry. There is no reason to apply grease to the bushings. There is nothing to attract dirt and cake and build up that creates wear when you have grease, oil and dirt mixed together. The suspension system goes from 45 degrees to 25 degrees for varying moisture and materials that can be screened.
Picking up the screener, transporting it and moving it around on site. The SLG series screeners do not have wheels or hitches because it takes away from the versatility and portability of the machine. This machine is about 10 feet 3 inches wide. An opening that is 12 feet it gives you the ability to go in behind the building, on a hillside, down in a hollow, in an area where the ground is soft. You have the ability to pick this screener up and move it to where you want to screen and do your screening right close. It is closer and gives you a better production rate because you are not moving material all over. The SLG screeners all come with a pocket system that is designed into the structure. It allows you to come in with a set of palette forks. Basically pick the screener up and pack it anywhere you want to go. Pack it on a trailer and transport it to the job site. Move it around on-site. The pockets make it extremely portable and versatile. We also designed bucket transport lugs that allow you to come in with your machine’s bucket, pick it up with your bucket and pack it around. It’s great for guys that don’t want to take pallet forks to the site or don’t have them. The machine has the capacity to be picked up with a bucket. These are the bucket transport lugs. On the 108 they are quiet heavy. Their burned out of 1 inch plate. Then holes are pierced through the sides of the plate where we install heavy walled tubing and weld them in place. It gives the lift lug internal strength so it doesn’t twist and warp when you are picking the screener up and packing it around. The lugs weigh about 70 pounds. You want to eat a big breakfast when you are moving them around and install them into the screener. It’s as easy as sliding them into the pockets. You’ll see on the backside of the lugs there is a hole that has been pierced on the top and bottom sides. That allows you to put a pin through the backside so the lift extensions cannot come out. It gives you the security of packing the machine around and not worrying about the lugs coming out of the screener. The lugs are both 70 pounds. They are nice and strong and durable. They really add to the versatility of moving the screener around on-site very easily. Once you have the screener where you want it, go up and take the pin out of the back side, pull the lugs out, and you can basically throw them beside the screener. They are there for you when you want to move the screener again. It gets rid of the necessity of having pallet forks with you all the time if you don’t want to carry those around.
I wanted to talk about the riser box for the 108 machine. The RB is the riser Box. It is constructed of 4X4 tubing. It has 3/8 plate that is laser cut with laser cut holes for the assembly. It comes with 4 winches on each side that you connect a 4-inch wide strap on each side connected to the screener so it can be moved in one piece. It weighs about 900 pounds. In combination with the screener that weighs about 3800-3900 pounds. It puts the total weight at about 5000 pounds. The 28 tall riser box when underneath the 108 moves the feed height to 10 foot 6 inches. It allows for 5-6 yards of material on each side of the screener. That is important. For example, if you have a 3-yard loader coming in feed, taking material, you want material on both sides so he can come in and get a full bucket without moving the screener around because you are pushing on opposing material on the other side. On the riser box, 10 foot 6 inch feet feed height. Off the riser box that feed height is 8 feet. That is important because if you are feeding it with a bucket tractor or a skid steer and it was up on the riser box you would be trying to look the top of the machine to see yourself feeding it. Being able to take it off the riser box and bring down the feed height down to 8 foot, you are then sitting comfortably in your machine. You can see the entire side of the screen deck. Connecting and disconnecting the riser box from the screener will take about 5 minutes. It is a simple procedure. The 4-inch wide strap connected to the side of the screener connecting the riser box. Place the load bar into the winch, push down, pull up the tab and let the winch come up. Then unravel the strap and let the strap come off. Do that on all for corners. When you want to put it back together place the strap on the top, wind it through the winch, push down on the bar, latch it, take the bar back out. It’s simple and can be done in about 5 minutes. More versatility means easier operation and more productivity.
