Besides the mill geometries there exist several easy to control and reasonably wellunderstood parameters unique to mechanochemical reactions. As mentioned above, the rotational speed (planetary ball mill) or milling frequency (vibrational ball mill) are an easy to adjust parameter to control the energy input in the milled powder.

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].
