Ball mill drive motor choices - IEEE Conference Publication. Abstract The time has come to re-think the approach to mill drive motors because of the growth in size of newer ball mills, the starting torque restrictions of some of the newer mill drive configurations, and the softness of some utility services.
1. The variable frequency control technology transforms the ball mill drive system to meet low running speed and high starting torque requirements, and makes ball mill running speed continuously adjustable. There is no shock current when the motor starts running, enough starting torque and full protection functions.
