Ball Milling an overview | ScienceDirect Topics

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].

This means that, often, shutting the mill down will cause the discharge end liners to loosen, and the bolts to begin leaking. Equally so, the feed end liners will loosen quicker if the size of the feed becomes larger than it should be. The amount of impact required to break the larger rock also shakes up the liners. Again the bolts will begin ...
