This and further arguments led to the increased share of VRM for the grinding of finished cement. Taking into account that.
Mills. With the exception of coal mills, MPS mills are equipped with an external material feed system to reduce pressure losses. Thanks to the optimal design of the nozzle ring, a fluidized bed above the nozzle ring is still used for high efficiency drying of the raw material, even at reduced gas speeds of 40–50 m s. MPS vertical roller mill.Vertical roller mill in the cement plant is smaller than the size of product from the power plant ball mill. It can be concluded that the process of grinding coal into fine particles for cement or power plant consumption uses less energy when grinding is done with a vertical roller mill rather than a ball mill.

Because of simple scalability and low energy consumption, the vertical roller mill is a key part for single mill cement lines. The limits of material throughput of VRMs are, unlike other mill types, not defined by the comminution process itself but by the transmissible torque of the drive train.Roller mill is a form of compression mill that uses a single, double, or triple cylindrical heavy wheel mounted horizontally and rotated about their long axis either in opposing pairs or against flat plates, to crush or grind various materials. One of the rollers is run by a motor and the others are rotated by friction as the material is drawn.

The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the.NGC’s MLX Series for Vertical Roller Mills (VRM) feature a unique combination of strength, reliability and durability not available in standard mill drives.
