In 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
The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Calculation Backup: the formula used for Critical Speed is: N c =76.6(D0.5) where, N c is the critical speed,in revolutions per minute, D is the mill effective inside diameter, in feet. source: SME Mineral Processing Handbook, Page 3C4.
Critical speed 76 % GM in II chamber 217 t Both the chambers of the cement mill were charged with 80% of the designed charge, • Empty heights of both the chambers measured to calculate the ball charge, % filling and estimate the power consumption at mill shaft. Based on the empty height measurements, charging of
