In the 1970s, Vertical Roller Mills (VRMs) became increasingly dominant for grinding raw materials, mainly for the cement and power industries, due to their high energy efficiency and excellent drying capacity. The VRM's function is to crush the materials into very fine particles, just prior to being stored or after the primary crushers.

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 circuits.
For the new VRM cement grinding system, the cement producer contracted with an equipment supplier based in Bethlehem, Pennsylvania for a proven mill design that was originally developed in Japan during the early 1980's.
