The cone crusher works louder, so if there is noise, it will be ignored. This requires our staff to pay more attention to prevent the noise problem from causing irreparable damage to the cone crusher. Let’s see which ones below The reason caused the noise problem of the equipment.

1. The fit clearance of the main parts of the equipment. The clearance between the main shaft of the cone crusher and the cone bushing is more complicated than that of the ordinary sliding bearing. The clearance value is large and different, and the upper mouth is sm and the lower mouth is large. In this way, the size of the fit gap is very important. If it is not appropriate, noise will occur and it will easily generate heat, which will affect the operation of the equipment. The other is the gap between the eccentric bushing and the frame bushing. It is also required to have a large value here, but it will increase the load and cause noise. Therefore, the fit clearance of key components be set according to requirements.

2. Movement analysis of equipment. The cone crusher will generate inertial force during the operation process, causing shock and vibration, which will cause noise. At present, the method of adding a balance weight on the big gear is gener y used to reduce the impact vibration and reduce the noise to the extent of the hard *. But when choosing the balance weight, it should be as sm as possible, otherwise it will affect the normal operation of the crusher.

3. The machining accuracy of the parts is not high. The design and processing of the components of the cone crusher are unqualified, or the accuracy is not high, resulting in poor over quality of the components. It can be imagined that the inst ation on the equipment will affect the over operation of the equipment, and the components will continue to be affected by repeated impacts. Friction, the noise of the equipment cannot be eliminated fundament y. In general, if the internal factors are not eliminated, the noise will continue to exist.
