  • 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
