Ideal Rpm For Ball Mill

  • 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

  • What it is the optimun speed for a ball mill

    Oct 18, 2006· Congratulations on your ball mill! You'll want to further reduce your motor speed by 3:1 to mill more efficiently. Right now, your RPM is just slightly under the speed where the media won't do any work. The optimum speed for your jar to turn is around 90 RPM like Frozentech said.
