planetary ball mill gearing result in very high pulverization energy and therefore short grinding times [10,11]. The type of planetary ball mill used in industry is the Retsch Planetary Ball mill PM100 [12]. Furthermore, the principles of horizontal ball mill operations are limited regarding the fineness of the powder after milling.

An increase in the number of balls had a minimal impact on the milling energy during BPR increment for two reasons: First, the weight loss of the ball led to a decrease in its kinetic energy and a consequent reduction in milling efficiency. Second, the degree of filling of the mill was raised so the balls mobility became more difficult and as a ...

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].
