In addition to ball mills, one of the other common mills in factories is the vertical roller mills (VRMs). In contrast to grinding by ball mills that need other devices to dry and separate powder, VRM performs separation, grinding, and drying processes just in one machine and reduce the number of devices in a close circuit.

coal in EGUs. The current dominant design is a pulverized-coal (PC) unit, in which coal is ground via a pulverizer to a fine powder and then combusted in a burner. 1 PC units are the most prevalent technology in the coal EGU fleet and represent about two-thirds of the current units progressing and under construction (Shuster, 2011).
The application of vertical-roller-mills (VRM's) for ore grinding is part of the second strategy. The grinding parts of a Loesche mill (Fig. 1) are a rotating table (1) with a horizontal grinding track and rollers (2), which are pressed onto the table by lever arms and a hydro pneumatic spring system.

The term Vertical Mill denotes equipment with the following characteristics A rotating, circular grinding table that turns around a vertical shaft Spherical, cylindrical, tapered rollers that are pressed on to roller paths on the surface of the table A source of pressure on the rollers A stream of gases flowing upwards around the table, …
Use of hot gas generator Historic test results show cement plants are able to increase production up to 37 percent* and decrease energy consumption by up to 17 percent* using TAVERO® VM additives. For example, a cement plant in Europe was running a VRM and spraying water at 1.5% and milling at 100° C.
Thermal stressing in vertical roller mills when drying and grinding very moist materials has led to development of improved designs to cope with these conditions. 4 The most common way to generate heat for drying raw materials in the mill is by utilizing a hot gas generator (HGG) to produce high temperature gases to drive off the moisture.
Raw mill fans: Raw mill fan in cement industry carries gas and raw meal. The pressure drop in raw mill fan is very high. If a vertical roller mill is used for raw grinding in cement industry then a large raw mill fan is installed. Usually cement industries use centrifugal fans to carry out this process. 4.
Fluidized Bed Drying: Hot gas entering the grinding chamber below the grinding rolls fluidizes the entire grinding chamber. This promotes rapid efficient drying of all material types, including lignite and sorbent. Large open area through grinding chamber allows particle terminal velocities to be maintained while fluidized by heated gasses. 3.
