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.
A ball mill consists of a hollow cylindrical shell that rotates about its axis, with balls occupying 30-50% of the volume to facilitate grinding as the shell rotates. Applications of ball mills include grinding metallic powders, carbon, coal, cement, fertilizers and other materials.
