Cement grinding Vertical roller mills versus ball mills

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.
