stone crusher for sale

The cone crusher is a kind of equipment with large crushing ratio, large processing capacity and high degree of automation. During operation, it is inevitable that failures such as abnormalities in the discharge hole of the cone crusher will occur. So what is the reason for the abnormality of the discharge port of the cone crusher?

First.There is leakage in the main valve. During the long-term working process of the cone crusher, the spring in the main valve will be fatigued, or impurities will be mixed in the hydraulic oil, which will cause the pressure set by the main valve to drop. Pay attention to check whether the main valve has oil return, and judge the condition of the main valve. If there is oil leakage, it must be cleaned or replaced.

Second.The pressure relief valve is damaged. The function of the safety valve is to ensure the pressure value of the system. In the case of long-term work, its setting value may change. You can observe the lifting and lowering of the moving cone in the ball valve after the safety valve is closed, and then determine whether it has damaged, and if damaged, replace it immediately.

Third.The control valve is damaged. In the hydraulic system, there are usually two control valve groups, which are special fluid-contact check valves that allow the cone crusher to rise and fall under no-load conditions. By detecting the condition of the moving cone, the condition of the regulating valve can be analyzed. If the moving cone has not changed, the speed should be adjusted.

Fourth.The V-shaped sealing strip of the oil cylinder is worn out. The V-shaped sealing ring on the hydraulic cylinder piston is used to isolate the hydraulic oil and lubricating oil. If the sealing ring is damaged or worn, the hydraulic oil and lubricating oil will be mixed, affecting the normal operation of the spindle. It can be judged by observing the oil level of the lubricating oil. If the lubricating oil of the horizontal axis is not lacking, but the oil level of the main oil rises, the seal is worn out and needs to be replaced.
