In the grinding process heat will be generated and the cement will be heated up. The temperature of the cement leaving the mill will be dependant on the temperature of the materials (especially the clinker) fed to the mill and to features of the mill and the grinding process. It will typically be in the range from 90 to 120 deg. C.
Vertical Roller Mill Working Principle When the vertical mill works the motor drives the grinding disc to rotate and the grinding roller rotates around the grinding roller shaft driven by the disc. The material entering from the feeding port falls in the center of the grinding disc and moves towards its edge under the action of centrifugal force.

Cement grinding Vertical roller mills versus ball. today is the most used mill for cement grinding Over the last three decades the vertical roller mill has bee the preferred mill for grinding of raw materials The grinding efficiency of the vertical roller mill bined with an ability to dry grind and classify within a single unit gives the vertical roller mill
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 majority of the particles in the bed are considerably smaller than the thickness of the bed.
Vertical Roller Mill In Cement Production Process . At present cement production process industry widely adopted vertical roller mill as a cement raw materials improves the automation of cement production line in the cement production process not only solves the slag of the impact on the environment but also provides a lot of cement to the market to meet the social development

There are three types of cement manufacturing processes wet semidry and dry processes. In the wet/semidry process the raw materials are produced by mixing limestone and water (called slurry) and blended with soft clay. In dry process technology crushed limestone and raw materials are ground and mixed without addition of water.
