Grinding Media Wear Rate Calculation in Ball Mill - 911 MetallurgistApr 29, 2017 . In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the balls in the mill, the work done by a ball is proportional to its weight.cement mill specific wear rate,A comparison of wear rates of ball mill grinding media (PDF .It gives accurate predictions of the service life of wear resistant alloys in mill liner and grinding media applications. In this paper the BMA test methodology was applied to investigate the wear rates of four grades of grinding media using two small laboratory ball mills. The rankings obtained from the tests were identical with.
