The source and solution of cone crusher noise

The cone crusher mainly crushes large rocks. During the crushing process, high-speed rotation and collision will inevitably produce noise, which will affect the health of workers and cause partial damage to the equipment. What are the reasons for the noise of the crusher? The following introduces the causes and solutions of cone crusher noise: 　
　
1,Noise source 　　
1, The inertial force is usually produced during the operation of the cone crusher, which will cause the impact and vibration of the crusher and generate noise. 　
　
2, The gap between the components of the cone crusher. For example, if the gap between the main shaft and the cone bushing is too large, the stability of the machine will decrease, and the cone crusher will make noise; too large a gap between the offset bushing and the frame bushing will increase the impact load, and then generate louder noise. 　
　
3, If the processing accuracy of the cone crusher components is not high or unqualified, it will also affect the operation effect of the equipment. During use, the components will conflict and generate noise. 　　

4, The cone crusher is malfunctioning. When non-crushed materials enter the crushing cavity, noise will be generated; belt deviation will generate noise; during high-speed operation, the unbalance of the host will also generate noise. 　　

2,Solution 　　
1, Ensure the correct meshing of the bevel gears of the various components of the cone crusher, 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 gap value of the cooperation between the cone crusher main shaft and the offset shaft sleeve and the frame bushing is within a reasonable range, and the gap cannot 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 that the touch area of ​​the gear is uniform, extend the service life of the gear, and avoid noise. 　　

4, Install the shock absorption equipment on the base of the crusher, and try to choose a stable place when installing. 　
　
5, Pay more attention to the maintenance of the cone crusher, regularly check the use of parts, and replace damaged parts in time.
