Roller Mils are directly driven bevelwheel 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 the mils rollers.
The vertical roller mill (VRM) is firmly established in cement plants all over the world. The biggest issues facing plants are not due to the equipment itself, but more to do with how well mill maintenance is understood and how the mill is looked after following commissioning.
We have supplied vertical roller mills (VRM) for raw, coal, slag and cement grinding for several decades. 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.
