The correct sizes are often determined by trial and error, primary grinding usually requiring a graded charge of 10-5 cm diameter balls, and secondary grinding requiring 5-2 cm. Concha et al. (1988) have developed a method to calculate ball mill charge by using a grinding circuit simulator with a model of ball wear in a tumbling mill.
Grinding aids (GAs), also called grinding additives are introduced in liquid or solid form in the ball mill or vertical cement mills during grinding because of their anticipated merits. They can be divided into amines and their salts, polyalcohols, lignosulfonates, fatty acids, and fatty acid salts based on their chemical makeup [ 1 ].
