A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. It's mainly used in grinding raw materials and end products in cement plant. Raw mill is made up of feeder part,discharging part,rotating part,transmission part (reducer,samll transmission gear,motor,electric control) etc.

Raw material grinding can be divided into: Dry grinding process: The desired size of the raw material depends on the burning process requirements and is normally in the range of 15-20% at R90 microns. Wet grinding process: The material and water are introduced into the mill through a feeder. The product that comes out of the mill is a slurry ...
