- 60 mm diameter grinding media consumption
The correct sizes are often determined by trial and error, primary grinding usually requiring a graded charge of 10-5 cm diameter balls, while secondary grinding requires 5-2cm. 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.

For an improved understanding, the wear rate constant is directly related to the grinding media consumption rate expressed in grams of steel per kWh drawn by the mill, using the simple expression: where dr represents the diameter of the new make-up balls periodically charged to the mill.
