However, there is a great deal of information that describes the variation of the grinding kinetics with the ball size and the ball wear kinetics. It is possible then to incorporate this information into a grinding model and investigate the effect of the makeup ball size on the mill performance with various feed and product specifications.

Ball mill. A typical type of fine grinder is the ball slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
