A ball mill is a type of grinding machine that uses steel or ceramic balls to grind materials into a fine powder. It works on the principle of impact and attrition. Impact occurs when the balls are lifted by the rotating mill and then drop onto the material to be ground. The force of the impact breaks the material into smaller pieces.

A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for singlestage fine grinding, regrinding, and as the second stage in twostage grinding circuits.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. 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].
