Vertical Roller Mill In Cement Industry. Vertical roller mills, especially those common for grinding of cement raw materials, typically employ a hydraulic-pneumatic system to apply a grinding force to the material bed.During operation, these systems will contain pressurized hydraulic fluid in an isolated branch of the circuit consisting principally of cylinders and …
The Horomill can be described as a bed material compression mill, a multi-compression mill and as high capacity mills (Cornille, 1999). The introduction of high compression grinding technology brought many different applications and circuit layouts using high pressure grinding rolls (HPGR), vertical roller mill (VRM) and Horomills.
Vertical roller mills (VRM) have become the standard for grinding raw materials in the cement manufacturing process. However, despite the fact that more than 10 years has passed since the installation of the first VRM for clinker grinding was almost completed, many cement producers are still favouring ball mills for cement production …
