If you have one big bin you'll still have the same problem otherwise you'll end up with a few ton in the bottom that never moves. Assuming it behaves like grain and draws from the top down through the middle.

Two bins will allow you to empty right out, turn about.

Yes i think two bins that hold aload and half would be absolutely perfect .
