Grinding Media Wear Rate Calculation in Ball Mill. Wt = total weight of balls in the mill, W't = total weight of balls in any interval. w = weight of any ball. R = rate of ball wear. Rt = loss in weight of the mill charge in time T. It is equal to π/6Dm³ SNw. T = time required for any ball to pass through any interval.
