CHAENG vertical roller mill is an equipment with the ability to grinding, dryer,powder, and transmission. GRM vertical roller mill also has significant advantages, such as, high efficient, large drying capacity, finished product fitness is easy to adjust, low noise, low power consumption, simple process technology, low operation cost, and more. CHAEGN is also a wide variety of material for cement, mining, power, chemical industry, industrial waste treatment and other fields.

The vertical roller mill produced by CHAENG is including GRMR raw material vertical mill, GRMS roller mill, GRMK cement vertical mill,GRMC coal vertical roller mill, etc. These equipment dealing with the cement raw material, clinker, slag, steel slag,fly ash,coal and anthracite coal,metal,and non-metal ore materials.

GRM vertical mill structure characteristics

1 - mill speed is fast, high grinding efficiency, compact structure.

2 - simple operation, stable operation, small vibration.

3 - grinding part adopts horizontal mill and the structure of cone roller, the relative speed difference is small, low metal consumption, grinding parts use 8000 hours, normal and easy to repair.

4 - roll ring and mill liner wear little influence on yields, yield reduction of < 5%.

5 - drying ability is strong, can use all the preheater waste water drying of 7% of the raw material, the use of auxiliary heat source water drying 15 to 20% of the raw material.

6 - sorting part adopts the combination of dynamic and static combined efficiently cage classifier, raw meal fineness control strictly, adjust agilely, raw meal fineness R80 mu m = 10 ~ 15%, R200 microns or less 1.0%.

7 - each roller relatively independent to pressure grinding mill wheel material, can be part of the work roller, four high mill when he worked in two roll yield can be up to 70% of the rated output.

8 - roller for thin oil lubrication circulation way;Roller bearing seal USES three fluorine rubber skeleton oil seal.

9 - the wind ring area and keep-off height can be adjusted according to the working condition.

10 - roller to lift falls, the realization of no-load start;Roller can rely on oil cylinder action automatic outside casing, easy maintenance.
