During the cone crusher production process, sometimes due to some special reasons, the rotating cone speed suddenly increases, the equipment vibrates violently, the safety spring bounces, the working current increases instantaneously, and the return temperature rises sharply, making the equipment unable to operate normally. This is The common fault of cone crusher is speeding. So what are the causes of speeding? And how to solve the problem of cone crusher speeding?

Why does the cone crusher appear to be "speeding"?

In cone crushers, due to the failure of the dust-proof device or loose sealing, part of the dust enters the lubricating oil circuit, resulting in poor lubrication between the bottom of the crushing cone and the spherical bearing, and between the pump cone and the eccentric sleeve. The oil temperature of the lubrication system decreases. If the viscosity continues to rise and the viscosity drops, dry friction will occur, which will lead to overspeed. There are two main reasons for the speed of the cone crusher:

Due to poor lubrication, the spherical surface of the moving cone and the bowl-shaped tile are abnormally worn, causing the overall assembly of the moving cone to decline, resulting in a reduction in the gap between the moving cone and the copper sleeve. Finally, the copper sleeve is deformed, and the main shaft is in partial contact with the inner hole of the copper sleeve.

The gap between the main shaft and the inner hole of the same sleeve is too small, causing the same sleeve to hug the main shaft, and the main shaft rotates at high speed with the eccentric sleeve.

The consequences of cone breaking speed car are so terrible

As a frequent failure of the cone crusher, it will not only affect production efficiency, but also damage equipment parts. Its main consequences are as follows.

If the cone crusher overruns when running under load, the crushed ore will not be discharged in time, and the ore from the previous process will continue to enter, which will inevitably cause blockage of the frame, cause overload operation of the equipment, cause the red sleeve to burn, or even Talk about accidents such as broken bevel gear teeth.

Therefore, the cone crusher flying is still a relatively serious problem. If it is not handled properly, or the stop is not made in time, it may even cause irreversible damage to the equipment. Friends should pay more attention and take precautions.

The solution to the cone crusher is here, and you don’t have to worry about it anymore.

After the previous popular science, we all know that the failure of lubricating oil and the too small gap between the freezing cone and the spindle bushing are the two main reasons for the cone to run away. The solution is naturally to suit the case.

1. If the overspeed is caused by lubricating oil failure, you should select the appropriate lubricating oil for the cone crusher according to the instructions for use. Pay attention to the two indicators of viscosity and fluidity. You can also install a water seal and dust-proof device to check the tightness of the retaining ring and annular retaining ring to prevent dust from entering the lubricating oil circuit.

2. It is caused by the gap between the moving cone of the spring cone and the spindle bushing being too small. Then we need to fix the spindle bushing and the eccentric sleeve to prevent relative movement between the two, and also ensure the assembly clearance of the inner and outer holes of the spindle bushing. , allowing the spindle to contact the spindle bushing along its entire length.
