##### Ball wear and ball size distributions in tumbling ball mills

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 ...
