Problem #1 they are rated 40lb/cubic ft and the coal i have been getting is 50lb/cu ft. This coal stuff is like cocain. I have access to a couple old feul tanks gears are grinding now. What ever I come up with is going to be outside. I plan to get the coal in summer so the water can drain out all summer so it wont freeze up.
He is looking for a silo to hold a semi -trailer load,that much will not fit on 1 or 2 gravity bins, he wants it to be outside storage,gravity bins need a roof .His idea of a BIG fuel tank standing on end will work,he just has to create the right bottom outlet for it . A gravity bin might work for his inside bin.The above quote is from the original poster & it is his first post about this issue.
