Product Description

PE Jaw Crusher Fixed Swing Jaw Plate

Jaw plates (fixed and swing jaw plate) are the most important wear parts of jaw crusher. We use high manganese steel with chrome as the material to make sure the quality.

Raw materials are crushed to small aggregates between movable jaw plate and fixed jaw plate. So movable jaw plate impacts raw material directly during the operation-time. Supposing that it is damaged, raw materials will impact the movable jaw of jaw crusher and the machine service-life will also be affected.
 

Jaw crusher generally bears the role of "head breaking" in crushing operations, and is the "host" in crushing operations. The crushing effect of jaw crusher depends on its jaw plate. The jaw plate is subjected to plastic wear and cutting wear in use, so it is required to use materials with high hardness to resist plastic fatigue and cutting wear, and a certain toughness to prevent brittle spalling or fracture. In the actual selection of jaw plate, it is necessary to fully understand the working conditions and wear mechanism, and choose the jaw plate rationally. The following four aspects to consider how to choose the material of jaw
crusher jaw plate:

1.Improve the hardness of the jaw plate: the larger the jaw crusher specifications, the greater the lumpiness of the broken material, the greater the impact load of the jaw plate. At this time, when choosing the material, we should first consider improving the hardness of the jaw plate under the premise of ensuring its toughness.

 

2.Consider the hardness of materials: the jaw plate should be different for different broken materials (such as granite, quartzite and limestone); The higher the hardness of the material, the higher the hardness of the jaw plate.

 

3.Considering the strength of moving plate and fixed plate: moving plate and fixed plate force and wear mechanism is different, the moving plate bears the impact force is larger, therefore, the toughness should be considered first; The fixed plate is supported by the frame, so hardness can be given priority.

 

4.Consideration of technical and economic effects: DENP also takes technical and economic effects into consideration when selecting jaw plates, striving to achieve high quality and low price and market competitiveness. At the same time, the rationality of the process should also be considered to make the production plant easy to organize production and control the quality.
