the mill supplier. Ball mill torque curve:- Cascading point is at 60°, independent of speed. Figure 2 The torque speed characteristic curve for a recent ball mill is shown in Figure 2. Mill suppliers define the starting torque at an angular displacement of the charge. The cascading point of this mill is at angle of 60°. This implies that a
When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pull-in torque, and 225% pull-out torque. These assume no greater than a 10% voltage drop at the motor terminals. V-BELT Ball Mill DRIVE V-belt or poly-V drives are generally used on grinding mills consuming 350 HP or less.
8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.

converter based drive systems provide benefits that improve the ball mill operation. FIXED SPEED CONFIGURATIONS The key issue to operate a mill in a fix speed mode is the starting. A squirrel-cage motor or a synchronous motor started direct on line without any help of a frequency converter normally cannot produce sufficient starting torque.
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.
