Ball mills are suitable for low and medium moisture content in the range of five to six percent and are preferred for abrasive material. The main advantage of VRM is higher grinding efficiency and the ability to accept material with higher moisture content. Normally the energy consumption level in VRM is 10 to 20 percent lower than in ball mills.

The VRM is a type of grinding mill that uses a vertically oriented, multilevel cylindrical roller to grind materials into extremely fine powders. The key components of a VRM are the grinding rollers and the grinding table. The grinding rollers are hydraulically loaded and held against the grinding table by means of hydraulic cylinders.

The VRM can be divided into two types, one airswept and the other overflow type without air involved (Altun et al., 2015). An airswept VRM includes a crushing system and a powder separation system, which can be used alone to produce micron sized products. An overflow VRM is often used as a precrushing equipment for crushing cement clinker.
