How does a ball mill work? Ball mill grinders work on the principle of impact and attrition. The ball mill machine contains a hollow cylindrical shell that rotates around its axis, becoming a tumbling ball mill. The impact of the balls that drop from the top of the shell therefore reduce the size of the material at the bottom of the shell.

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].

which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2" or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200). High speed dispersers with no media run
