1. Cylindrical Shell: The ball mill consists of a hollow cylindrical shell that rotates about its axis. The shell is usually made of steel, stainless steel, or rubber. 2. Liners: An abrasion-resistant material such as manganese steel or rubber typically lines the inner surface of the cylindrical shell to protect it from wear due to the grinding action.

Ball mills are commonly used in single stage fine grinding, regrinding, and as the second stage in two-stage grinding circuits. Ball mills are available in both wet and dry designs, depending on the application. Ball mills have been constructed with standard final product diameters ranging from 0.074 mm to 0.4 mm in diameter.
