The vertical roller mill equipped with an internal classifier is often said to be more energy efficient than tumbling mills working on the same material and the same size step ( Gerold et al., 2012). It is long established in the cement industry and gains more and more importance in the industrial mineral and iron ore sectors.
In the study the advantages of vertical roller mill are discussed over ball mills. VRM construction, its process and parameters which affects the performance and productivity of vertical roller mill are discussed. Also the consequences of variations in parameter explained.

In a ringroller mill, the material to be milled is fed into the grinding section. The moving roller forces the coarse material against the stationary grinding ring. The particles emerge from the machine slightly finer than they entered. Usage Examples. Vertical spindle mills are used in the mineral industry to grind materials such as phosphate ...
Fuel is combusted to produce heat for the clinker production process; coal is the traditional fuel used in China's cement industry. The raw coal from the stockyard is crushed in a hammer crusher and fed to the coal mill. The coal mill is a vertical roller mill, in which the coal particles are collected in a bag filter through a grit separator.
The application of vertical roller mills (VRMs) for ore grinding is a part of the strategies against rising energy consumption (Reichert et al., 2015). The VRM technology was introduced in the mid'90s for grinding clinker and slag by LOESCHE (Schaefer, 2001). Fig. 1 illustrates the grinding parts of a Loesche vertical roller mill.
