The products includes five series: crusher, sand making machine, powder grinding mill, mineral processing equipment and building materials equipment.dual motor grinding mill drive synchronous motor,Apr 172014 This paper reviews various Mill drive configurations and improved synchronous motor characteristics when used with more advanced Current Source Inverter (CSI) drives. It will also review the different synchronous motor excitation types and resulting performance characteristics with VFD control for new or retrofit installations..
Synchronous motors Synchronous motors are usually of the low torque type in order to reduce the inrush current and the load of the mill drive train. A starting coupling is required to limit the motor torque during mill start. In the case of a high-speed synchronous motor a hydraulic coupling can be used. Low-speed low-torque motors
dual motor grinding mill drive synchronous motor. The motor is a directdrivegear motor engineered to attach directly to your GrainMaker grain mill. The very slow speed is critical to keep heat at a minimum while grinding grains in order to preserve important nutrients that arent found in most storebought breads.
the SAG mill with the dc drive. The ac synchronous motors used in the gear and gearless drives have a higher efficiency than the dc drive. Thus: for large motor horsepowersthe efficiency would affect the operating cost of the operation. Typicallythe overall drive efficiency when using an ac synchro-nous motor is 920whereas the equiva-
