1. Introduction. The vertical roller mill (VRM) is heavy mechanical equipment that used in the cement materials industry to process cement, slag, and coal cinder (Pani & Mohanta, Citation 2015).The equipment always needs to work in the environment of heavy load, high temperature, high pressure, high corrosiveness, …

Vertical roller mill (VRM) technology has become an integral part of the cement industry, offering several advantages over traditional grinding mills. Today, this type of grinding machine is becoming more and more popular in both the raw material grinding process and the cement grinding process.

A vertical roller mill is a grinding equipment for many industries such as minerals, cement, and ceramics. It is also used to grind slag and nonmetallic ores. The VRM decreases the number of equipment in the grinding circuit by combining the drying, crushing, grinding, and particle segregation in one unit [ 1 ].

A two-compartment ball mill with a highly efficient separator is still procured for new cement grinding units installation, although the vertical roller mill has now become a true. Vertical roller mill. The feed is ground by pressure and friction between the horizontal rotating table and 4 to 6 grinding rollers in the VRM.

Abstract. 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 …
