Or did I misread your reply? Is it that you never get close to the
mill when it's running due to safety factors?

Bingo. Just 'being there' is foolish. More than one mill has exploded
during operation.

Why are the materials more explosive during mixing than they are
during handling after they're mixed?
Becaue they are "aerosolized" - ALL of their surface area is exposed
to air. The only "safe" way to mill pyrotechnics is in an inert
atmosphere - and even then it is not "safe" because oxidizers are part
of the mix.

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?
