More### Ball Mill Critical Speed

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical ...

Working with a 7.32 m diameter and 3.66 m long mill, Napier-Munn et al. [4] observed that the breakage rate for the finer size fractions of ore (say 0.1 mm) at lower speeds (e.g., 55% of the critical speed) was higher than that observed at higher speeds (e.g., 70% of the critical speed). For larger sizes of ore (in excess of 10 mm), the breakage rate was lower for mills rotating at 55% of the ...
