Vertical roller mill  widely used in metallurgy, building materials, chemicals, mining and other fields, perform the grinding of materials processed mining products, suitable for processing Mohs hardness of seven or less, and all kinds of non-inflammable material in the humidity below 6%.

Vertical roller mill  hydraulic system is an important system components, the main role of the hydraulic system is to open and close the roller, that is, when the mill grinding chamber inside the wear parts wear, you can open the mill shut down both sides of the grinding rolls to replace or repair parts inside. Vertical roller mill hydraulic system including hydraulic station, connected to the fuel tank and hydraulic tube mill rolls and other components.

Vertical roller mill hydraulic system works as follows: milling equipment hydraulic device to lift and put down mainly to the roller and set up, when to lift the roller when the hydraulic oil in the hydraulic cylinders can be time through pumps, switching valves, etc. into the cylinder, the cylinder due to the additional hydraulic oil lead to increased pressure, so the cylinder cylinder following an upward thrust, this force can push the piston upward movement; at the same time the fuel tank inside the upper cylinder hydraulic oil goes through the oil return pipe hydraulic station; when the pressure came on the roller, to open the way for pipeline valves to relief, or by switching valve to switch, so that the pump in the hydraulic oil into the cylinder out of the upper part of the cylinder, resulting in the Under the thrust, this force can push the piston downward movement, while the lower part of the cylinder block in the hydraulic return as compressor stations.

These are roller opening and closing works, pressure roller capable of supporting open, so that relief can be closed, which is a convenient vertical mill wear parts replacement and maintenance reasons.

Vertical roller mill hydraulic device is designed to mill internal parts for maintenance and easy to replace and set up, it can not control aspects of the regulation of small roller and disc from the size of a large roller in controlling aspects of opening and closing, and. Its hydraulics are and pressing means together with the work, and the pressure inside the device is added to the hydraulic oil pressure can open the roller, the roller and the relief can be closed, which is a two mutual cooperation and mutual essential systems, both also designed for the convenience of the user interaction with the system. Vertical roller mill hydraulic device is an important means, but the most important is to be added inside the hydraulic oil, the user should promptly join.
