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.

The grinding action in a ball mill is achieved through two primary fragmentation mechanisms: attrition and the impact. Impaction happens when the grinding media (balls or hard pebbles) bump into each other and with the material being ground. This leads to the fragmentation of the substance into pieces of smaller size.
