Mill Critical Speed Calculation

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.

Effect of lifters and mill speed on particle behaviour ...

The power of a ball mill is obtained by multiplying the corresponding torque with the mill speed. Thus, the torque curves and power curves are similar. Fig. 20 shows 78 groups of DEM simulation results for the effect of rotation rate, lifter height, and lifter number on the power draw of the ball mill. Each curve represents the variation of the ...
