The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. It is increasingly used as a solution for efficient grinding.
VERTICAL ROLLER MILL DRIVE GEARBOX. Roller Mils are directly driven bevel-wheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque ,the gear unit also has capability to take up the reaction forces from the the griding force of
Mar 25, 2015 The hydraulic system of vertical mill is an important system, the main function of the hydraulic system is to break the grinding roller, which is when the internal grinding cavity wear parts wear, can stop open on both sides of the grinding roller mill, to replace the inside parts or repair.
Apr 01, 2017 Vertical roller mills VRM have found applications mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classification and if necessary drying operations in one unit and enables to decrease number of equipment in grinding circuits.
