VRM components are subject to severe wear. This is particularly true when grinding materials with high silica content and slags, such as are found in cement mills. This wear has a direct impact on a plant's bottom line: a worn VRM roller reduces grinding efficiency, increasing the energy demand and costs of milling.

The VRM for cement grinding offers a significant advantage in power savings. Typically, the VRM uses 50% less power than a ball mill when grinding the same clinker to 3900 Blaine. VRMs are also much more adept at handling hot feed compared to ball mills.The simple and compact vertical mill layout is cost competitive to build and offers many options for layout, even in …

The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills.
