The cone crusher works louder, so it will be ignored if there is noise. This requires our staff to pay more attention every day to prevent the noise problem from causing irreparable damage to the cone crusher. The reason caused the noise problem of the equipment.
1. The matching clearance of the main components of the cone crusher. The clearance between the main shaft of the cone crusher and the cone bushing is more complicated than the clearance of ordinary sliding bearings. The clearance values are large and different, and the upper mouth is smaller and the lower mouth is larger. In this way, the size of the gap is very important. If it is not appropriate, noise will occur, and it is easy to generate heat and affect the operation of the equipment. The other is the clearance between the eccentric shaft bushing and the frame bushing, which also requires a large value, but excessively large loads increase the noise. Therefore, the clearance of the key components must be set according to the requirements.
2. Motion analysis of cone crusher. During the operation of the cone crusher, inertial force will be generated, which will cause impact vibration, which will cause noise. At present, the method of adding a balance weight to the large gear is generally used to balance to reduce the impact vibration and reduce the noise to the degree of the hard top. But when choosing the balance weight, try to keep it as small as possible, otherwise it will affect the normal work of the crusher.
3. The machining accuracy of cone crusher components is not high. The design and processing of the cone crusher components are unqualified, or the accuracy is not high, resulting in poor overall quality of the components. It is conceivable that the installation on the equipment will affect the overall operation of the equipment, and the components will continue to be affected by repeated impact Friction, so that the noise of the equipment cannot be fundamentally eliminated. In general, the internal cause will not be eliminated and the noise will continue to exist.
