The feeder (A) deposits raw material into the base of the Roller Mill (B) at a rate determined by pressure variations with the grinding mill. Plows located ahead of each roller direct the material upward and between the grinding rolls and the heavy alloy steel bull ring, where it is ground to the specified size.
Vertical roller mills and ball mills represent two clearly distinct technologies. However, with proper adjustments to the operational parameters of the vertical roller mill almost identical cement properties can be achieved by the two mills that satisfy the cement user's demands.Nevertheless, the two types of mills have their distinctive merits.

The grinding process in ball mills and vertical roller mills is fundamentally different [15]. Following are advantages of VRM over Ball Mills with reference to these issues: - • Strong drying ability - Inlet hot air from Kiln can dry materials with 20% water content. (max moisture 20% vs. 3% in ball mill) [15], [16]. •
The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...
