Explosive Manufacturing, Ingredients, Gunpowder: Manufacture of black powder was accomplished originally by hand methods. Ingredients were ground together with a mortar and pestle. The next step was to use crushing devices of wood (wooden stamps), also operated by hand, in wooden or stone bowls. The stamping process was gradually mechanized and, about 1435, the first powder mill driven by ...

Quick Easy Black Powder Ball Mill Here's Your Next Ball Mill What is a ball mill? What is it used for in fireworks making? From Wikipedia,, (this article contains an animation of what the contents of a ball mill do during operation):
As the ball mill rotates, the lead balls will crush the chemicals together, forcing some of the potassium nitrate into the pores of the charcoal and sulfur. At the same time, the entire mass will be reduced to a super fine powder. The longer the ball mill runs, the stronger the black powder will be.
Black powder can be made by milling the components singly and screenmixing together. Charcoal and potassium nitrate can be purchased premilled now, as well. Using a rock tumbler, you can make black powder faster by milling the charcoal and potassium nitrate separately. 3 component milling takes much longer to make good powder.
