Ball Mill Starting With Slip Ring Motors And Liquid Rheostat

18-09-2011· We operate ball mills with dual-coupled 3500hp 4160v wound rotor induction motors. We have recently experienced frequent arcing of the slip rings which seems to start on the center ring. The arcing damages the ring badly which requires us to shutdown the mill to sand it smooth again.

If the mill is able to "find its own level" when unpowered, it will tend to roll back until the surface of the chargeThe torque required goes above running levels until the charge begins to tumble.the ball mill motor are generally slip ring type with LRS stator and starting current is limited to 1,5 times to rated current , the ball mill provI ed on a number of autogenous mills.
