vrm in cement plant
The cement clinker grinding plant or cement grinding station acts as an individual production line in the last period of the cement production process. In the finished product period, the cement clinker is ground by adding moderate mixing materials and then forms the finished cement
1. The relative sliding between the millstone and grinding roller is very small, thus the rotate speed could be fast and the grinding roller pressure is high. Therefore the output is higher compared with other types grinding roller under the same specifications.
2. It integrates the drying, grinding, selecting at the same time, with the simple technical process and lower noise.
3. It’s suitable for the air swept and material circulation system. The latter can greatly reduce the power consumption of ventilation system.
4. Ventilation ring gap in mill can be flexibly adjusted according to the distribution of the material, in order to reduce ventilation resistance and power consumption.
5. The roller can automatically lift or fall down, realizing no-load starting to reduce the motor starting torque.
6. Roll mill can turn out the cylinder shell under the effect of double roller cylinder for the convenience of maintenance.
7. There is an efficient cage classifier device in it, with a sensitive adjustment of fineness, better load adaptability, and the high efficiency of the powder classifying which can reach above 90%.
8. Low cost on operation and maintenance;
9. One-time investment and low operation cost;
(Less used field area and the waste gas from the pre-heather can be used.)
