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.

The ball mill works by imparting rotational motion to the drum, which in turn rotates the grinding media. As the drum rotates, the balls cascade down from a higher position, striking the materials that need to be ground. This impact, combined with the friction between the balls and the materials, breaks down the larger particles into smaller ones.
