Abstract 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 ∝ r2 + 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 Experimental data are presented which.
