  • Mill Critical Speed Calculation2019-4-15 · Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assely 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.
