Ball mills produce 1 to 50 ton/h power of which about 70 to 90 percent would pass a 200 mesh screen and the energy requirement of a ball mill is about 16 kWh/t. In the case of the batch-operated mill, a measured quality of a solid to be ground is charged into the mill through an opening in the shell.

Ball mill is an important grinding machine widely used in mineral dressing plants, cement plants, thermal power plants, fertilizer plants, and other fields. It mainly uses the grinding media inside the grinding chamber to refine raw materials and reduce their particle size. There are three ways for grinding media to pulverize materials: 1.

This means that during one rotation of the sun wheel, the grinding jar rotates twice in the opposite direction. This speed ratio is very common for Planetary Ball Mills in general. Planetary ball mills with higher energy input and a speed ratio of 1:-2.5 or even 1:-3 are mainly used for mechanochemical applications.

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 milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
