ball mills, the starting torque restrictions of some of the newer mill drive configurations, and the softness speed is given by the following calculation: Time = WK2x Speed Change 308 x Avg Acc Torque trains used with ball mills because of the torque shock when the clutch is energized utch Table 4 .
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.
