Wet milling, also known as wet grinding, is a process through which particles that are suspended in a liquid slurry are dispersed in that liquid by shearing or crushing. Once the milling process is complete, these particles are ready for use or can be dried and separated for incorporation into additional products. Wet milling is more complex ...

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].
