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].

Ball mill, also known as tumbling or pebble mill is milling equipment that encompasses cylindercontaining balls and is mounted on a metallic frame that can be rotated along with a longitudinal axis. The large ball tends to break down coarse feed materials and the small ball mill to form fine products by reducing void spaces.

When high energy ball mills are used, the temperature of the milling tools is often increased. Many researchers in the 1990s used to halt the process for a certain period of time in order to lower the milling temperature. In practice, this technique replicates the time required to manufacture the materials. This issue is viewed as a significant ...

Highenergy ball milling (HEBM) is a treatment of powders, which uses the action of the milling media to mix, disperse, activate and form composite structures [14]. The milling devices exist in various designs. Usually, they are divided into two groups: lowenergy and highenergy mills [5]. The processes occurring during HEBM are deformation,

A feature of ball mills is their high specific energy consumption. A mill filled with balls, working idle, consumes approximately as much energy as at fullscale capacity, that is, during the grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity.
