BALL MILL DRIVE MOTOR CHOICES

The starting torque characteristic of this type of ball mill is not linear. Figure 2 shows the graph of mill speed versus torque requirement: Figure 2 The graph clearly shows that the torque requirement exceeds 120% at 80% speed. This is why the starting torque of the drive motor should be at least 130% of full load torque.
