ROLLER MILL. Used in cement industry. Vertical Mills used for Pre-grinding of clinker (lumps to coarse powder) Finish grinding (lumps to powder) of. Coal/Petcoke for kiln Raw materials for kiln Cement, OPC or mixed Slag, pure or mixed VRM Functions Vertical Roller Mill (VRM) - Details
Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is regarded as a breakthrough.

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.
