Introduction of
Cement Vertical roller mill (VRM) is mainly used to grind cement clinker into fine powder during cement production, which can also be used to grind various materials such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite etc.
Vertical Roller Mill has a Low Investment Cost
VRM(Vertical Roller Mill) system can crush, dry, grinding, classifying, so the system is simple, and occupation area is about 50% of ball mill system. In addition, it can be the outdoor installation that reduce a large number of investment costs.
Vertical roller mill has a Low Operation Cost
High efficiency: roller compacted materials directly onto the grinding disc, so power consumption is low. Compared with ball mill, it saves energy consumption by 30% ~ 40%.
Less wear and tear: As the roller is not in direct contact with the disc, and material of the roller and liner is high quality, so life time is long.
High Drying Ability
As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with different humidity.
Stability of Product Quality
As the material stays in the VRM for a short time, it is easy to detect and control the product particle size and chemical composition, to reduce duplication of milling, stable product quality.
Maintenance Convenience
By repairing fuel tank, rotating the arm, it is fast to replace the roller sleeve, and liner, and reduce the downtime loss.
