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

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 itsMill Critical Speed Calculation,14/10/2015 · The speed of the mill was kept at 63% of the critical speed The face angle was varied from 90 to 111 degrees for the three types of configuration 1, 2 and 4, as shown in the figure Also, the height of the lifter bar in configuration 3 was changed to observe the trajectory It was observed that the ball trajectories could be controlled by the face angle and the height of the lifter barsSAGMILLINGCOM : Mill Critical Speed Determination,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
