How to solve the problem of loud noise of cone crusher

The cone crusher crushes large rocks. During the crushing process, the high-speed operation and violent collision make the crusher inevitably produce noise. This will not only affect the health of the workers, but also cause certain harm to the equipment. Apart from the noise caused by improper installation of the crusher, what other reasons are there?
 

1. Noise source

1. The cone crusher generally produces inertial force when it is running, which will cause the impact and vibration of the crusher, which will cause noise.

2. The gap between the components of the cone crusher. For example, the matching gap between the main shaft and the cone bushing is not suitable. If the gap is too large, it will cause the operation to lose stability, make the body of the cone crusher vibrate and make noise, and the cooperation between the eccentric shaft sleeve and the frame bushing Clearance, if the clearance is too large, the impact load will be increased, resulting in greater noise.

3. The processing accuracy of the cone crusher components is not high or unqualified, which will also affect the operation effect of the equipment, and the components are constantly rubbing during use, resulting in noise.

4. If the cone crusher breaks down, noise will occur when non-crushed objects enter the crushing cavity, noise will be generated when the belt deviates, and noise will also occur when the main machine is unbalanced during high-speed operation.

Two, the solution

1. Ensure that the large and small bevel gears of each part of the cone crusher mesh correctly, eliminate the reciprocating sliding and impact between the gears, prolong the service life of the gears, and fundamentally eliminate the source of noise.

2. Make sure that the matching clearance value between the main shaft of the cone crusher, the eccentric shaft sleeve and the frame bushing is within a reasonable range, and the clearance should not be too large or too small.

3. Increase the accuracy of the bevel gear of the cone crusher, pay attention to whether the quality is qualified, ensure the uniform contact area of the gear, prolong the service life of the gear, and avoid noise.

4. Install shock-absorbing equipment on the base of the crusher, or make shock-absorbing ground and foundation, and try to choose a stable place during installation.

5. Usually pay more attention to the maintenance of the cone crusher, regularly check the use of parts and components, and replace damaged parts in time.
