Fig. 2 shows the variation of the average torque and power with mill speed for the ball mill described above with a fill level of 50%. The torque increases slowly until the peak is attained around N=80%.As the amount of cataracting increases, the balance of the charge improves and the torque required to maintain the asymmetric charge position …
