The point where the mill becomes a centrifuge is called the "Critical Speed" and ball mills usually operate at 65% to 75% of the critical speed. Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.

The critical speed of the ball mill was calculated to be 76 rpm. It is observed that the grindability of the ball mill or, in other words, the amount of fines increases with respect to the overall effect of increase in the number of balls, time of grinding and speed (rpm) of the ball mill. However, with increase in particle size and Ball Mill
