In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table. The energy input to the material during one passage between grinding rollers and grinding track is relatively low. The thick-ness of the material bed between roller and table is a multiple of the particle size.

Vertical Roller Mills (VRM), High Pressure Grinding Rolls (HPGR), Vertical Shaft Impact Crushers (VSI) and more recently, Horizontal Roller Mill (Horomill) have saved the specific power by 45–70% when compared with a ball mill circuit [8], [10]. Now a days Ball mills and HPGR are installed together as a common unit.
The basic structure of a VRM for cement grinding is the same as for raw material and coal grinding. Raw materials (such as clinker, slag, fly ash, gypsum, limestone or pozzolana) are fed into the mill and ground by compression and shearing forces between the grinding table and two or four hydraulically-controlled rollers.
The result is a high grinding efficiency and extremely stable mill operation. 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.
VRM (raw mill) VRM (raw mill): drift and maintenance free measurement to control the recirculation of dust laden primary air to optimize the grinding process* Bypass: to control the amount of bypassed gas to reduce the accumulation of pollutants in the process.*
