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].

• The scale of reaction determines the size and the type of ball mill. • Vessels for laboratory vibration ball mills are normally restricted to a volume of 50 cm3. Milling material: • The material density determines the energy entry and therefore, the choice of material influence the dissipative heat formation during ball milling.

1. As the name suggests, the ball milling method consists of balls and a mill chamber. Therefore over all a ball mill contains a stainless steel container and many small iron, hardened steel, silicon carbide, or tungsten carbide balls are made to rotate inside a mill (drum). 2. The powder of a material is taken inside the steel container.
