Possible, but probably not. Would be a good test to see though. I would try to lower the spin plate while a jam was occuring. This may be simplier said then done though. If the material starts to flow, then you would know that the hopper and material are just not setup/designed correctly and right on the edge of plugging. If it did flow, you would more then likely see ratholing, where the material flows only from the middle of the pile and the sides fold in. This is the age old issue of first in, last out. This would indicate the hopper walls are to resistive (carbon steel vereses stainless steel) to material flow, along with shallow walls, not enough slope.
