Hi Jeff, A small hammer mill would be fine, but you need to run it under negative pressure to keep from making a mess. Start at the back end with a small blower good for 12" suction. Then a fake baghouse (three old Shopvacs in parallel would be fine.) Then, a tall skinny, cyclone (high-efficiency) with a downleg terminated with a couple butterfly valves operating 90deg out of phase as an airlock. This dumps into your collection bag/drum.
Of course, any kind of feed auger makes things more fun. Get a fine screen for the mill and don't push things to prevent a conflagration which would ruin anyone's day. The cyclone is about 99% efficient by weight, so it takes the load off your "baghouse". An even simpler solution is a homebrew ball or rod mill.

This would be for charcoal Fireball production. All advice will be appreciated. Reduction might be 2 mm to dust. Enough dust to fill in the larger 2 mm particles. Might be possible to have some particles larger than 2 mm. Production is difficult for me to pin down but lets say 400 lbs/hr (180 kg/hr). More is better but less would be OK for now. The more I think about it a lot less would work for now. Would a farm hammer mill with cyclone bagger be a formula for a dust storm?
