  • ETAP Motor Starting Study for 600kW Ball Mill

     · The problem with ball mills vs a simulation like ETAP is that the mill initially is a torque load that is dependent on rotation angle until the charge start to tumble. ETAP only simulates the torque vs speed as a curve. Best bet would be to use a torque peak right off zero speed and then drop down to a more constant torque type of load curve.

    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.
