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 shells 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 (in rpm) = /sqrt(D d) with D the diameter of the mill in largest grinding ball you will use for experiment (also expressed in meters) There are a lot of equations to calculate the critical rotation speed, but it is not accurate.
