The weight loss can then be used to calculate the specific wear rate (g/kWh) of the media. It is important to note that wear rates are often different for different materials and even different types of mills. For example, a ball mill typically has a higher wear rate than a rod mill. Operating conditions also play a role in determining wear rates.

— The theory of the calculation of the size distribution of the equilibrium mixture of balls in a ball mill is developed. The differential equation is solved for wear laws of the form wear rate per ball ∝ r 2 + Δ where r is ball radius. Δ = 0 gives the Bond wear law and Δ = 1 gives the Davis wear law. Methods of determining Δ are illustrated.
