PROCESS CONTROL FOR CEMENT GRINDING IN

2017-10-27  VRM shown in Figure-1 uses hydraulically hard-pressed conical shape 2-4 rollers against the horizontal revolving grinding table. To enhance comminution, the axes of table and rollers do not traverse in the plane of the table and approximately 150 inclination angles between roller axis and table, the relative motion appertain both sliding and rolling. Mixed raw materials are fed using the feeding belt conveyer through feeding mouth along with feed pipe. With the help of louver ring, a rising air current at the periphery is directed; while the rollers are rotating, material is heading onto the center of the table and thrown outward by rotation beneath the rollers. Coarse material fall onto the feed table, fines pass out with the air current and the air sweep passes all the way through an integral rotating classifier. After the last feed input the central to the mill table, due to mill and roller’s relative movement, materials get into the grinding layer between the roller
