Ball Mill
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.
