14.7 Use of ball milling. 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 introducedBall Mill Explained saVRee,The size of the balls depends upon the size of the drum, typical ball sizes are two to three inches in diameter (fourinch balls are also possible).
