SOBY Grain Pump Loop with SG100 

1:55 What is happening with grain, that sticks between chain and gear ??

What program did you use to create the animations?

Why do you elevate grain twice, seems like a waste of energy. Leg from pit should transfer to the top of bins or else just high enough to get into the low leg. The one continuous transfer loop seems like a great idea but it will be a nightmare when it plugs up.
