Technical requirements for jaw crusher side guards

1. Material requirements

The material of the jaw crusher side guard plate should be selected with high strength, high toughness and good wear resistance. Common materials include manganese steel, alloy steel and high chromium cast iron. Among them, manganese steel has high wear resistance and high toughness, but relatively low strength; alloy steel has high strength and good wear resistance, but relatively poor toughness; high chromium cast iron has high hardness and good wear resistance, but relatively low toughness. Therefore, choose the appropriate material according to the specific use requirements.
2. Structural requirements
The structure of the jaw crusher side guard plate should be reasonably designed to ensure that the stone will not splash out during the crushing process, while saving materials and reducing costs. Usually a segmented structure is adopted to divide the side guard plate into several pieces for easy replacement and maintenance. In addition, it is necessary to ensure that the gap between the side guard plate and the Jaw Plate is not greater than the opening of the crusher feed port to prevent stone blockage.
3. Process requirements
The processing technology of the jaw crusher side guard plate is also relatively particular, and its surface flatness and dimensional accuracy should be ensured. Usually casting or forging and other processes are used to ensure the material uniformity and structural tightness of the side guard plate. At the same time, during the manufacturing process, attention should also be paid to the trial installation of the side guard plate to verify its combination with the jaw plate to ensure that there will be no problems with stone splashing and equipment wear.
In summary, the side guard plate of the jaw crusher is an important part of the crusher, and its quality and structure have a great impact on the service life and production efficiency of the crusher. Therefore, various factors need to be strictly considered in material selection, design and processing to produce high-quality side guard plates.
