This paper deals in first place with roller mills for raw material processing. For grinding coal, slag, cement, etc., adaptations to mills and systems have to be made. 2. FUNCTIONS OF THE ROLLER MILL The vertical roller mill fulfills 4 main functions in one compact piece of equipment: ¢ Grinding « Drying ¢ Separation ¢ TransportFigure-1. Vertical roller mill for cement grinding [13]. VRM shown in Figure-1 uses hydraulically hard-pressed conical shape 2-4 rollers against the horizontal revolving grinding table.

Numerical Study of the Flow Field in a Vertical Roller Mill
In order to reduce the larger pressure resistance (pressure difference between inlet and outlet) of a vertical roller mill, the flow field in the vertical roller mill is numerically simulated by CFD technology. Based on the simulation results, the reasons that led to the larger pressure resistance of the vertical roller mill is studied, offering the Cement raw material is the mixture of mainly Limestone & other constituent such Iron oxide, Shale etc. having different moisture contain depending on composition & deposit. We offer the mills with optimized process technology to evaporate the moisture by employing the hot gases and intricate mill design provides efficient grinding.VRM AMCL Machinery Limited
