Introduction. Vertical roller mill (VRM) is a type of heavy-duty and energy-intensive grinding equipment for many industries, such as cement, steel and chemical industries. It is used to grind slag, nonmetallic ore and other block and granular raw materials into required powder materials. The fine powders can be used as raw materials The vertical roller mill (VRM) is a type of grinding machine for raw material processing and cement grinding in the cement manufacturing process.In recent years, the VRM cement mill has been equipped in more and more cement plants around the world because of its features like high energy efficiency, low pollutant generation, small floor area, etc..

Cement grinding Vertical roller mills VS ball mills

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 paper analyzes the interrelation of: motion, particle size of ground rice grains, displacement, and grinding in a roller–plate mill.
