When this happens, we bypass the soft start, and the mill starts right up. Inrush current across the line is in the neighborhood of 1300 amps. We don't like to do this often, because it leads to increased failure of the stator windings. I would say that the motor stalls. The soft start tries starting it until we get a squirrel cage trip on a GE ...

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
