Looking at setting up a new grain dryer and want to include a handling system to move dry grain to a row of four 42000 bushel bins. Grain dryer supplier also sells convey air blower systems and that is the way they would like to set up the system. We have three phase power on site so motor size is not an issue. Just wondering if anyone has a system like this and what your thoughts were if you would do it again and if the pipes wear out with the abrasive grain. Or are we better off with a leg and top drag. Thanks

They work pretty good, noisy so we put a muffler on the intake, helped a lot. If you raise beans get the heavy duty pipes, I am still confused about that one but we had to switch the out on the smaller bin we use for beans, only lasted about 40,000 bu but the set of regular pipes. As for corn we have had over a million bu through them pipes and no problems. Very reliable, I think its probably time to go through the air lock.

Most notable thing we have trouble with the air filter when in freezing temps with the wrong wind catches the moisture from the drier so be a little proactive on the location of the blower

The amount of bushels we have run threw it a leg system probably would have been better in the long run but it would be interesting with the bin setup we use. 15, 45, 125. I didn't believe it would work on that 125 but its been fine. I guess in that aspect it is easily expandable

SW do you auger into a surge bin on the dry side of the drier or do you have the airlock directly under the discharge of the drier?

We were going to set up a 6400 bushel surge bin out of the dryer so pneumatic system would not have to run continually and the four bins would not hold all the harvest so we could transfer out of that dry bin and haul to another bin site or directly to elevator or do custom drying.

No surge bin, got the airlock right under the drier discharge, the one we are running is 30hp on a 1500bu/hr drier, usually running 800 threw there

SW what diameter are the pipes in your system. Why do you think you might have been better off with a leg system with the volume you've put through.

 

[SWFarmService]

Pipes are 6" , I guess what I was thinking a grain leg would be 5hp vs 30hp and maybe I would save a few years on my ears not that its that bad but loud compared to the leg

We are actually adding a dryer to our system and plan on moving the grain away from the dryer pneumatically . Plan on a 30 HP Walinga blower with 6' line , the VFD will be tied into dryer outlet discharge speed to match the blower to the discharge of the dryer . Suggested to us by Walinga to reduce grain damage .
If we could have made it work we would have went with a grain loop on the dry side of dryer , lower HP , lower cost to purchase and lower grain damage (I would think)
We have a 12" grain loop on the wet unload side of our existing system that works well , but it is only 1 season old .

We use legs in our existing system but we have some fairly long spouts that give us grief plugging in the grain retarders .
