effect of cement mill temperature on cement properties

Cement grinding Vertical roller mills versus ball mills

This will usually not be necessary with a ball mill due to its higher energy consumption resulting in a sufficiently high temperature in the mill. Grinding of blended cement with wet additives may require supplementary heat from a hot air generator whether the mill is a ball mill or a vertical roller mill.
