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].

Ballmills are categorized into four types depending on the motion generated to produce momentum in grinding balls and act upon the material with various milling forces. These are planetary, tumbling, vibratory, and attrition mills. Planetary ball mill. Planetary ball mills are simple and efficient in producing ground/pulverized material.

Effect of ball mill speed. Ball mill speed is also a key factor affecting the grinding and cell disruption of SMB samples. A better extraction efficiency may be achieved at a higher speed. Therefore, different ball mill speeds (4 m/s, m/s, 5 m/s, m/s, 6 m/s) were studied. However, it is found that the ball mill speed in this case had no ...
