Ball Milling - an overview ScienceDirect Topics
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].

Mixing of Powder - an overview ScienceDirect Topics
Ball mill diameter, media size and mill revolutions per minute (rpm) control the process of powder mixing and particle size reduction (Upadhyaya, 1998). For given mill size and media, too low an rpm extends the process time, whereas too high an rpm leads to poor cascading of media, leading to inefficient particle size reduction.
