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

critical speed equation of a ball mill. Ball mill critical speed formula equation derivation. The "Critical Speed" for a grinding mill is defined as the rotational speed whereThis is the rotational speed where balls will not fall away from the mill;s may use the Mill Liner Effective Width calculation to determine this value.
