Hi, I searched and could not find much on bulk storage so I thought I would ask. I am working on a hopper to store pellets in. Is there any down side to this other than having a hard time making a dumping system to get the pellets out. I tried a auger but it did not work out it would cut the pellets like a meat grinder. So I'm working on a large sort of ball valve. Hopper will be 3'x3' x 70"H and totally enclosed.
