Raw mill uses vertical roller mills, while cement mill uses ball mills. Q: Which is more energy-efficient, raw mill or cement mill? A: Cement mill is generally more energy-efficient than raw mill because the clinker particles in the cement mill are already in a fine powder form, and less grinding is required.
For drying the wet raw material it is necessary that prior to the mill start up the grinding plant is.heated for some time.Otherwise the cold grinding plant would take away too much heat from the drying process and the finish product would not be dry – handling problems in the meal transport and silo extraction would follow.

A rawmill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement.Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The rawmilling stage of the process effectively defines the chemistry (and therefore physical properties) of the …
These differences between cement grinding and grinding of raw materials made it a serious challenge to obtain a good performance of a vertical roller mill in cement grinding.
