PROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL ROLLER MILL (VRM) A REVIEW Vijaya Bhaskar B. and Jayalalitha S. Department of Electronics and Instrumentation Engineering, SASTRA University, India E-Mail: [email protected] ABSTRACT The power ingesting of a grinding process is 50-60% in the cement production power consumption.
In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table. The energy input to the material during one passage between grinding rollers and grinding track is relatively low. The thick-ness of the material bed between roller and table is a multiple of the particle size.
Coal Vertical Roller Mill (VRM) is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grinding roller onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness.
Vertical roller mills (VRM) have found applications mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classification and if necessary drying operations in one unit and enables to decrease number of equipment in grinding ...
