  • Cement Mill Soft Start

    Cement Mill Soft Start

    Feb 12, 2009 A ball mill requires higher torque to turn until it reaches a speed where the balls drop onto the down-going side of the mill. Starting torque can also be srongly affected by the position of the ball load in the mill at start and by balls sticking together due to sitting motionless.

    Electromechanical Dynamic Behaviour and Start

    This paper presents a dynamic simulator of the electromechanical coupling start-up of a ball mill. The electromechanical coupling model based on the dynamic model of the ball mill, the characteristic equation of the clutch, and the dynamic model of the induction motor is established. Comparison between the simulation results of angular speed, load torque and current obtained from the model ...
