Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill. With this in mind, it is interesting to make a qualitative comparison of the ball size distributions which should be generated by 76 mm pearlitic carbon steel balls versus 76 mm martensitic alloy steel balls in the 2.93 m mills.
