• ##### Ball Mill Critical Speed Mineral Processing &

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

Enter the width of a mill shell liner. Note this is not the width of a lifter! You may use the Mill Liner Effective Width calculation to determine this value. The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Mill Actual RPM: Enter the measured mill rotation in revolutions per minute.

• ##### Ball Mill Critical Speed & Working Principle

19-6-2015· The effect of Ball Mill RPM speed going from sub-critical to super-critical helps understand the Ball Mill Working Principles of ball-on-ball VS ball-on-shell grinding. The Motion of the Ball Charge The input energy in ball milling is that applied by the drive to impart motion to the mill charge.
