where bij is primary breakage distribution function of a particle of size j breaking into size i. Using population balance approach Austin and Klimpel then derived the equations for predicting the equilibrium ball size distribution assuming a linear wear law when one-ball and two ball sizes are used. Balls are added to compensate for ball wear inside the mill and that results in a continuous .
2019-4-27 · In Grinding selecting calculate the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often the ball used in ball mills is oversize just in case. Well this safety factor can cost you much in recovery andor mill liner wear and tear.
