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. S = weight of material from which balls are made.

2. Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed for most efficient grinding.
