The cone crusher mainly crushes large pieces of rock. During the crushing process, high-speed rotation and collision will inevitably generate noise, which will affect the health of workers and cause damage to the accessories of the equipment. What are the other reasons for the noise of the crusher? The following introduces the causes and solutions of cone crusher noise:
       1. The source of noise
　　 1. Inertial force usually occurs during the operation of the cone crusher, which will cause the crusher's shock and vibration and cause noise.
　　 2. The open space between the components of the cone crusher. For example, if the space between the main shaft and the cone bushing is too large, the stability of the machine will decrease, and the cone crusher will announce noise; if the space between the offset bushing and the frame bushing is too large, the impact load will increase, and then er noise will occur.
　　3. If the processing accuracy of the cone crusher components is not high or unqualified, it will also affect the operation 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 occur; belt deviation will cause noise; noise will also occur when the main engine is out of balance during high-speed operation.   　 2. Solution
　　 1. Ensure that the 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 cooperative open space value of the cone crusher main shaft, the offset shaft sleeve and the frame bushing is within a reasonable range, and the open space 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 prevent noise.
　　4. Install shock absorption equipment on the base of the crusher, and choose a stable place as much as possible 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.
