Using a Ball Mill for Black Powder Production: How It Works
Loading the Mill. A cylindrical shell revolves around its axis to form the ball mill. Metal balls (or other grinding medium) are fed into the mill together with the components of black powder (potassium nitrate, charcoal, and sulfur) within the shell. Using a ball mill to make mixed black powder is a specific operation, but safety is crucial.
