Increase The Durability Of Large Impact Crusher

Talking about how to increase the durability of large impact and impact

In the mining equipment, large-scale construction is a common and efficient crushing equipment, which is widely used in metallurgy, chemical industry, building materials and other departments. It is a working cavity composed of a rotor. The rotor is subjected to huge crushing force and friction of materials, and is easy to wear. In order to protect the hammer, a wear-resistant lining is generally installed on the surface of the rotor, which is also called a impact crusher. When working, the impact crusher wears faster than the upper part due to the action of gravity, and bears a huge crushing force and friction of the material. On the other hand, since the impact crusher is directly in contact with the material, it often fails quickly due to wear and tear. Not only does it reduce the efficiency of work, but it also increases the cost of materials. Therefore, the durability of the impact is extremely important. The following are some effective improvements for the durability of impacting impacts for large buildings:

1. Large-scale construction uses impact to break the structure and material selection. At design time, the impact crusher of the rotor should have a tooth peak to the valley of the tooth. In this way, in addition to the extrusion effect on the material during the crushing, there is also a bending effect, and the material is relatively easy to be broken. In order to prolong the service life of the impact crusher, the impact crusher for small and medium-sized large-scale buildings is designed to be vertically symmetrical. When the lower part is worn, the adjustable head is used, and the large-scale large-scale building is designed to be symmetrical with each other. In order to wear, the impact crusher can be exchanged to reduce the cost.

2. When assembling and assembling the impact board. The impact crusher must be firmly attached to the hammer. The two should be leveled. The soft metal (such as lead, zinc, etc.) should be used as a gasket between the impact crusher and the hammer and fastened with bolts. When a large building is used for impact work, the impact crusher should not be loose, otherwise it will easily break or wear the impact crusher and reduce the service life of the impact crusher. Therefore, the impact crusher must be installed during assembly to extend the service life of the impact crusher.

3. Improve the process during actual use to extend the durability of impacting impacts for large buildings. In the actual production process, the impact crusher directly interacts with the material, and the crushing force is very large. Especially when crushing the material with high hardness, the bolt of the impact crusher is vibrated due to the increase of the crushing force, and the nut is loosened, so that the wear of the impact crusher is intensified and generated. Great noise, causing hidden dangers. In severe cases, the impact crusher is broken or broken to stop the equipment and affect normal production. In this case, usually only tighten the bolts and nuts before starting the machine. However, the problem cannot be completely solved. It is necessary to analyze the specific problems according to the actual situation on the spot and find ways to solve the problem in a practical way. For example, a spring anti-loose vibration damping device can be used to solve the looseness of the impact crusher during work, thereby prolonging the durability of the impact crusher and improving work efficiency. The specific method is to use a spring to make the bolt anti-loose and self-tightening device. The device is composed of an inner spring gland, a spring and an outer spring gland. The device is put on the bolt to tighten the nut, because the spring is pressed by the nut to a certain extent. After that, a strong anti-vibration effect is produced, and the bolt loose power generated by the huge crushing force is automatically compensated by the spring tensioning force, so the bolt is not loosened, thereby prolonging the durability of the impact crusher and improving the production efficiency.

The above points are simple to increase the durability of the impact board from the aspects of material selection, assembly and use of large-scale buildings. In short, in the actual use process, specific analysis can be carried out for specific situations, and appropriate and effective methods are adopted to improve work efficiency.
