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].

It is very noisy machine. 3. Ball mill is a slow process. 4. Soft and sticky material cannot be milled by ball mill 5. At low speed, the balls will slide or roll over each other and only negligible amount of size reduction will occur. 6. At high speed the balls will be thrown out to the wall by centrifugal force and no grinding will occur.

Ball Mills. A ball mill is one of the simplest and most common types of mechanochemical equipment (Figure 3) [38,39]. Sometimes this type of equipment is referred to as a "roller mill" or a "roller crushing mill" by mistake, because the mill drive resembles rotating rollers. In many mechanochemical studies, this mill is used as a ...
