OK, got it. Flour and gasoline are also highly flammable (or
explosive) when aerosolized. So, once they're mixed and put into more
compact containers, how much does the safety factor go up?

How often do you have to replace ball mills due to explosions?


Sorry, Larry, but that "aerosolized" concept doesn't apply with ball
mills, except when milling highly active metals, or naturally pyrophoric
materials (like, say, white phosphorus -- which doesn't mill well,
anyway, due to its plasticity). The danger in mills is from impact,
primarily.

I've had one mill explosion in 48 years of doing it. And that one was
not an explosive, but fine magnesium powder being only mixed, not milled
(but IN a ball mill jar).
