WEBBall mills are horizontal cylindrical vessels used to grind materials using balls as the grinding medium. The material is continuously fed into one end of the mill and discharged from the other end. The balls help grind the material by impact and attrition. Ball mills can operate continuously, batchwise, or as semiautogenous grinding mills depending on .

WEBBall 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].
