For raw grinding with relatively dry raw materials, the combination of the roller press and V separator is a viable alternative with far lower mill fan power. Cement grinding. For cement grinding, the technology development away from ball mills has taken a different route.
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. Abstract A cement company concerned about high powerfactor penalty costs requested an evaluation of the
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
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
This technical article relies on the great paper written by Barton J. Sauer (Siemens Energy Automation) which goes into essence of selecting the proper AC motor for cement plant applications. Selecting AC Induction Motors for Cement Plant Applications (on photo:3,500 kW ballmill drive for a ...
This paper focuses on the selection of AC induction motors for gyratory crushers, conecrushers and grinding mill applications. The criteria for motor selection includes: proper enclosure, driven equipment torque requirements, bearing life, temperature rise, starting requirements, ambient temperature, altitude and accessory requirements.

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.
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.
The driving motors used in the cement industry can be broadly classified as follows: Cement Mill drives Kiln drives Crusher drives Waste Gas Fan drives Compressor drives Function: Mining blasting limestone and clay. Rock fragments transported. Cement .
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
