Large wound rotor induction motors (WRIM) have been used in some industries for decades. In the cement and mining industries, high horsepower WRIMs are used on large grinding mills, where they have the advantage of controlled starting characteristics and adjustable speed capability. These motors are also used on large pumps in the water and waste industry.
LCI''S AND SYNCHRONOUS MOTORS APPLIED TO ROLLER MILLS For Presentation at the IEEEIPCA Cement Industry Technical Conference Salt Lake City, UT May 2000 By: James F. Zayechek G E Industrial Systems 1.

May 11, 2015· a grinding mill which consumes 6070% of the total electricity consumption of the cement plant[12]. A grinding mill (Ball Mill) is used to grind the cement clinker into fine cement powder. Grinding Aids are used to improve the grinding efficiency and reduce power consumption. This paper discusses the grinding aids mechanism and
In cement plants, proper specification and supply of AC induction motors is critical to project schedules and providing efficient production. This paper focuses on the selection of AC induction motors for cement mill applications, with reference to fan, kiln and vertical mill applications. The criteria for motor selection includes:
Wound rotor induction motors (WRIM) have been popular for decades in the cement and mining industry for starting and driving large grinding mills. In fact, until about 1985, a wound rotor induction motor was the only large ac motor that controlled starting characteristics and adjustable speed capability. Stator R ot r Slip Rings 3Phase stator
Abstract: Synchronous motors (SMS) continue to be a viable alternative to induction motors because of efficiency advantages. Since SMs have long been used to provide leading kvar for power factor (PF) improvement and to help with the device switching in loadcommutated inverter (LCI) drives, these machines are efficient prime movers for large mill applications.
