Becaue they are "aerosolized" - ALL of their surface area is exposed

No... that's not true of milling black powder. It CAN be true for milling
some metals (like Mg). The safety issue comes from the impacts the balls
make on one-another with explosive powder between them.

and the fact black powder has an oxidizer The potassium nitrate
means even an inert atmosphere doesn't make it safe because it can
self-deflagrate from compressive force alone.

Again, very true
