Vertical roller mill is typically designed to deal with industrial waste slag. Due to high physical and chemical activity, and potential hydraulicity, waste slag has been widely as admixture matters in the cement industry to replace the equal cement in the concrete to improve the quality and durability of the concrete.

After almost a decade cooperation with experts on vertical mill manufacturing and scientific research institutes both in home and abroad, the GRM series vertical mills dedicated to be developed and produced by chaeng, have the characteristics of reliable performance, compact structure, convenient maintenance and outstanding energy saving, etc., after incessant perfection. At present, we can produce the supporting raw material vertical mill,coal vertical mill, and cement vertical mill that can cater to 300-5000 t/d cement production line, and the series slag vertical mills with annual production capacity of 0.2 million tons, 0.3 million, 0.45million tons, 0.6 million rons,0.9 million tons and 1.2million tons.

Vertical roller mill Unique design characteristics

1.The compound separator improved power selection efficiency.

2.Has automatic function of roller uplifting and down falling and can realize idling startup.

3.Adopt the sealing of jointing arc board, simple and reliable in structure with good sealing effect.

4.Resorting to the roller turning equipment can conveniently turn the roller out of the mill for overhauling.

5.Mechanical limiting structure can avoid the direct metal friction and collision between roller and millstone, increasing the use security.

6.The operation pressure is low in hydraulic pressure system, decreasing the oil leaking failure and vibration of mill, which is conducive to operation and management.

7.Roller bearing adopts the concentrated cycle lubricating of thin oil, guaranteeing the running of bearing under the conditions of low temperature and pure grease and effectively prolonging the longevity of bearing.

Vertical Roller Mill Structure

Below is the structure of the vertical roller mill diagram, which is composed of a separator, roll grinding, grinding, pressure device, reducer, motor, shell and other components. The separator is an important component for ensuring product fineness, it consists of the drive system, rotor, guide vanes, a shell, a coarse powder blanking cone outlet, etc.

The grinding roller is the main components of compacted crushed to the material, which is composed of the roller sleeve and roll heart, axle and bearing and roller bracket etc.. Each friction has 2 ~ 4 grinding roller.

Grinding disc is fixed on the reducer shaft, driven by the speed reducer rotating disc.

The pressure device is provided an important part of grinding pressure, which is composed of high pressure oil station, a hydraulic cylinder, a pull rod, an energy accumulator and the like, can exert enough pressure to make the material crushing and grinding roller. But the spring pressure device.
