2021-2-18 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 cross-section 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

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(D-0.5) 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 3C-4.
