Buffer plate: Protects the key components of the impact crusher

In the field of industrial crushing, impact crushers are widely used due to their highly efficient crushing capacity and wide applicability. However, this kind of equipment is confronted with huge impact force and wear during operation, which poses a severe challenge to the stability and durability of the equipment. As a key component, the buffer plate is designed to effectively reduce impact force, protect equipment from damage, thereby extending the service life of the equipment and enhancing production efficiency. This article will conduct an in-depth analysis of the role of the buffer plate and its significance in reducing shock.

First, the function of the buffer plate
Reduce the impact force
During the operation of the impact crusher, the materials strike the rotor and the Impact Plate at high speed, generating a huge impact force. This impact force not only leads to the crushing of materials, but also causes severe wear and damage to the equipment itself. The function of the buffer plate is to absorb and disperse these impact forces, reducing the direct impact on the equipment. By installing a buffer plate between the impact plate and the rotor, the peak of the impact force can be effectively reduced, protecting the key components of the equipment from excessive stress.

2. Protect equipment components
Another important function of the buffer plate is to protect the key components of the impact crusher, such as the rotor, impact plate and hammer head, etc. These components are subject to high-intensity impact and wear during long-term operation, and are prone to fatigue cracks and damage. The buffer plate reduces the wear and fatigue damage of these components by absorbing the impact force, thereby extending the service life of the equipment. For instance, the buffer plate can prevent the impact plate from cracking due to frequent impacts, reduce the frequency of replacing the impact plate, and lower the maintenance cost of the equipment.

3. Improve production efficiency
The use of buffer plates not only helps protect the equipment but also improves production efficiency. By reducing the impact force, the buffer plate can ensure that the equipment is more stable during operation and reduce the downtime caused by equipment failure. In addition, the buffer plate can also optimize the crushing effect of materials and improve the crushing efficiency. For instance, in some cases, the buffer plate can guide the material to be distributed more evenly on the counterattack plate, thereby enhancing the crushing efficiency and reducing energy consumption.

Second, the material selection of the buffer plate
The material selection of the buffer plate is crucial to its performance and service life. Common buffer plate materials include high manganese steel, alloy steel and composite materials, etc. These materials have different performance characteristics and are suitable for different working conditions.
1.High manganese steel
High manganese steel is a commonly used material for buffer plates, featuring excellent toughness and wear resistance. High manganese steel undergoes work hardening when subjected to impact, significantly increasing its surface hardness and thereby enhancing its wear resistance. This material is suitable for working conditions with high impact and high wear, and can effectively absorb the impact force and reduce wear. However, the processing performance of high manganese steel is poor and the processing cost is relatively high.

2. Alloy steel
Alloy steel enhances the strength and toughness of the material by adding different alloying elements such as chromium, molybdenum and vanadium. Alloy steel has high hardness and good wear resistance, while maintaining a certain degree of toughness and being capable of withstanding considerable impact forces. This material is suitable for medium impact and high wear working conditions and can effectively protect the key components of the equipment.

3. Composite materials
Composite material is a new type of buffer plate material, composed of multiple materials, and has excellent comprehensive performance. For instance, some composite materials combine the high strength of metals with the elasticity of rubber, which can effectively absorb impact forces and reduce wear. The buffer plate made of composite materials not only has excellent wear resistance and impact resistance, but also features low processing costs and light weight, making it suitable for various complex working conditions.

Third, the design and installation of the buffer plate
The design and installation of the buffer plate have a significant impact on its performance and effect. Reasonable design and installation can fully leverage the role of the buffer plate, enhancing the stability and service life of the equipment.
1. Design optimization
The design of the buffer plate should be optimized according to the specific working conditions. For instance, the shape and size of the buffer plate should match the structure of the impact plate and the rotor to ensure that the impact force can be evenly distributed. The thickness of the buffer plate should be selected based on the magnitude of the impact force to ensure sufficient strength and toughness. In addition, the surface treatment of the buffer plate is also very important, such as sandblasting and painting, which can enhance its wear resistance and corrosion resistance.

2. Installation precautions
The installation of the buffer plate should ensure its close contact with the impact plate and the rotor to guarantee the effective transmission of the impact force. During the installation process, operations should be carried out strictly in accordance with the technical requirements of the equipment to ensure that the installation position of the buffer plate is accurate. At the same time, the installation status of the buffer plate should be inspected regularly. Any loosening or damage should be detected and dealt with in a timely manner to ensure the normal operation of the buffer plate.

Fourth, practical application cases
1.Ore crushing
During the ore crushing process, the impact crusher is confronted with tremendous impact force and wear. By installing buffer plates, the damage caused by impact forces to the equipment can be effectively reduced, and the service life of the equipment can be prolonged. For instance, after a certain mining enterprise installed high manganese steel buffer plates on the impact crusher, the wear of the equipment was significantly reduced, the service life was extended by more than 30%, and the crushing efficiency was also improved.

2. Construction waste treatment
In the process of construction waste treatment, impact crushers are used to crush materials such as concrete blocks and bricks. These materials have a relatively high hardness and exert a greater impact force on the equipment. By installing alloy steel buffer plates, the key components of the equipment can be effectively protected, reducing wear and damage. After a certain construction waste treatment enterprise installed alloy steel buffer plates, the maintenance cost of the equipment was significantly reduced and the production efficiency increased by 20%.

Fifth, Conclusion
As a key component of the impact crusher, the buffer plate is designed to effectively reduce the impact force, protect the equipment from damage, thereby extending the service life of the equipment and enhancing production efficiency. By rationally selecting materials, optimizing design and correct installation, the buffer plate can fully play its role and improve the stability and reliability of the equipment. In practical applications, the use of buffer plates not only reduces the wear and damage of equipment, but also improves the crushing efficiency and lowers the maintenance cost. Therefore, the application of buffer plates in impact crushers has significant practical significance and provides strong support for the development of the industrial crushing field.
