What are the causes and solutions for cone crusher noise?

The main work of cone crusher is to crush large rocks. During the crushing process, high-speed operation and violent collision make the crusher inevitably produce noise. This will not only affect the health of workers, but also cause certain harm to the equipment. So what are the causes and solutions for cone crusher noise?

Causes of cone crusher noise:

1. Cone crusher generally generates inertial force during operation, which will cause the crusher to impact and vibrate and cause noise.

2. The gap between the various components of the cone crusher. For example, the size of the clearance between the main shaft and the cone bushing is not appropriate. If the gap is too large, it will cause the operation to lose stability, causing the cone crusher body to vibrate and make noise. There is also a clearance between the eccentric sleeve and the frame bushing. If the clearance is too large, it will increase the impact load and generate greater noise.

3. The machining accuracy of cone crusher parts is not high or unqualified, which will also affect the operation effect of the equipment, and the parts will continue to rub during use, generating noise.

4. If the cone crusher fails, noise will occur when non-crushed objects enter the crushing chamber, the belt will deviate and cause noise, and the main machine will be unbalanced during high-speed operation.

Solutions to the noise of the cone crusher:

1. Ensure that the large and small bevel gears of the various components of the cone crusher are correctly meshed, eliminate the reciprocating sliding and impact between the gears, extend the service life of the gears, and fundamentally eliminate the noise source.

2. Ensure that the matching clearance value between the cone crusher main shaft and the eccentric 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 cone crusher bevel gear, pay attention to whether the quality is qualified, ensure that the contact area of ​​the gear is uniform, extend the service life of the gear, and avoid noise.

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

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