For the same amount of ball charge the number of balls in the mill decreases as the ball size increas Thus the S values are lower for larger balls However larger balls are capable of breaking large particles therefore the size at which the S value becomes maximum x m increases as the ball size becomes largerDec 08 32 Re how to estimate the wear rate for Ball mill Hey Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials With new balls sample of given size can be weighed before and after grinding a given tonnage and assuming uniform wear per unit of ball surface the total charge wear can be estimated
