CHAENG GRM vertical roller mill has the integrated functions of grinding, drying, powder selecting and conveying, with innovative technologies of high grind efficiency
CHAENG GRM vertical roller mill has the integrated functions of grinding, drying, powder selecting and conveying, with innovative technologies of high grind efficiency, strong drying ability, low noise, low power consumption and simple process. GRM vertical roller mill is innovative, environmental friendly and efficient, and it has won a number of Chinese technical patents. Especially, The new “one mill, three uses” vertical mill developed in 2015 by CHAENG led Chinese vertical roller mill development to a high peak.
The material through the feed tube fell into the center of grinding plate, and then the materials outwards the surrounding area of grinding plate at centrifugal force, to forms a certain thick layer of materials bed, at the same time material was crushed by number of rollers.
The materials continuous moving to the outer edge of the grinding plate, off the grinding plate materials rising with the hot air which enter from wind ring into the vertical roller mill, through the vertical roller mill shell into the middle of the separator, in this course materials and hot gas got a fully heat exchange, the water quickly evaporates.
Separator controls the finished product output size, greater than the specified size are separated and fall back to the plate, while meet the fineness demands are brought through the separator into the finished product warehouse.
Recent years, vertical roller mill is very popular in cement plants and ore processing plants because of its energy saving and low cost.
Parameters in the following table are showing the grinding operation index comparison between roller press combining ball mill and vertical roller mill in cement plant.
Conclusion: the vertical mill has remarkable advantages in power consumption, wear parts consumption and equipment maintenance!
1. Large output, high efficiency, all parts are manufactured by CHAENG independently.
2. Grinding roller bearings are lubricated circularly with dilute oil, which can ensure the bearings’ work at lower temperature, and moreover the quality and purity of lubricating oil are controlled, conducive to prolonging the service life of bearings;
3. Equipped with roller turning device which can turn the grinding rollers out of the mill, to make maintenance easy;
4. Compared with other types of roller mills, GRM vertical mill hydraulic system has low operation pressure, low oil leakage fault rate and high safety and reliability;
5. The combined-type separator has high powder selection efficiency.
6. Adopts full closed design with little dust pollution.
