Mill Critical Speed Calculation
15102015 Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied The mill was rotated at 50, 62, 75 and 90% of the critical speed Six lifter bars of rectangular crosssection were used at equal spacing The overall motion of the balls at the end of five revolutions is shown in Figure 4 As can be seen from the 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 Ball Mill Critical Speed Mineral Processing Ball Mill Critical Speed Metallurgist Mineral Processing Engineer 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 shellequation for calculating the critical speed of ball millIn most cases, the ideal mill speed will have the media tumbling from the top of the pile (the shoulder) to the bottom (the toe) with many impacts along the way The ideal mill speed is usually somewhere between 55% to 75% of critical speed Critical Mill Speed Critical Speed (left) is the speed at which the outer layer of media centrifuges against the wall Second Critical Speed (middle) is the speed at which the second layer of media centrifuges inside the first layer nth Critical speed Mill Speed Critical Speed Paul O AbbeThe 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 Result #1: This mill would need to spin at RPM to be at 100% critical speed : Mill Critical Speed
