It influences the final particle size and the quality of the black powder. Longer grinding durations and fasterrotating speeds produce finer powder. Overgrinding the combination might result in undesirable effects or risks. Safety Considerations. It is critical to take necessary safety precautions when using a ball mill to make black powder.

Ball mill under an iron dome posted in Safety: Is it safe to put my (homemade) ball mill under an iron dome? The dome perfectly fits onto my ball mill (there's room above the mill) and I can barely push my fingers under it. I'm asking, because maybe in case of an accidental explosion it might fly off and cause more harm, than flying media would cause. By the way, I would put it in a hole in ...

Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal ), and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer.

To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour. Your nitrate should be light and fluffy. If not, continue grinding it 'til it's fine powder with no chunks or grains.
