Product Description
The vertical roller mill has been widely used and promoted in the electric power, metallurgy, chemical industry,
non-metal industry because the overall efficiency attributed to energy-saving and low consumption is becoming
more and more evident in the cement industry.
Working Principle of vertical roller mill:
Material through the feed tube fell on the center of grinding plate, centrifugal force generated from the rotation of grinding plate uniformly scatters and flattens the materials outwards the surrounding area of grinding plate, to forms a certain thick layer of materials bed, the material was crushed by number of rollers at the same time.Driven by the continuous centrifugal force to keep the materials moving to the outer edge of the grinding plate, the materials off the grinding plate rising with the hot air which enter from wind ring into the mill, through the mill shell into the middle of the separator, in this course materials and hot gas do a fully heat exchange, and the water quickly evaporates.Separator controls the output size of finished product, greater than the specified size are separated and fall back to the plate, while meet the fineness requirements are brought through the separator into the finished product warehouse.
1) The combined classifier improves the powder selection efficiency.
2) It is not necessary to distribute material on the grinding plate before start-up.The roller can be lifted up and down automatically and start without load.
3) It is well sealed by welded arc plate and structure is simple and reliable
4) With the help of roller turning device, it is easily to turn the roller out for maintenance.
5) Both sides of roller sleeve can be used so that the service life of refractory material is extended.
6) Grinding roller limit device can ensure a certain space between roller and grinding table, which avoids the direct friction and collision between roller and grinding table and enhances safety
7) The grinding roller is driven by spinning grinding table.Pressure filling and adjustment and roller lifting can be remotely controlled without operator on-site.
8) The roller bearing is circularly lubricated by thin oil to enable it to work under low temperature and clean grease so that the service life is extended

Project:
One cement factory in China purchased GRMK53.41 cement vertical mill from CHAENG in 2012.This vertical mill is the largest cement vertical mill in China, adopting new efficient powder separator, easy to operate and operating stably.Its designed output is 220t/h, and the actual output is up to 260t/h.Cement produced by this vertical mill possess good quality not lower than that of ball mill, the leader of Meng Electric Group expressed his great satisfaction.
