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 Mill Application: Ball mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.

For instance, if your jar had in inside diameter of 90 mm and your milling media was 12.7 mm diameter lead balls, the optimum rotation would be 98 RPM. Optimum RPM= .65 x Critical speed (cascading action of the media stops) Critical speed = 265.45/sqrt (Jar I.D. - Media O.D.) with dimensions in inches.

The drive sets the grinding drum into slow rotation, whereby the bed of grinding media is activated. Ball mills are usually operated at 75% of the critical speed. If the speed is slower, the balls roll in a cascading motion, whereas at higher speeds, the balls are lifted and impact back against the bed (free-fall motion).

Based on the contents of this ball mill and the required final product, the mill operates within the cascade grinding mode (i.e. 50-60% critical drum speed). Figure 1.
