Design and selection of jaw plate
Latest company news about Design and selection of jaw plate

The jaw plate is the main part of the jaw crusher. There are movable jaw plate and static jaw plate. According to the different models of jaw crusher, there are multiple models and sizes, generally made of high manganese steel.

 

Folding design and material selection When designing, the broken tooth plates of the movable jaw and the fixed jaw should be tooth peak to tooth valley. In this way, in addition to the squeezing effect on the material during crushing, it also has a bending effect, and the material is easier to be broken. In order to enhance the service life of the crushing tooth plate, the crushing tooth plate of the small and medium-sized crusher is designed to be symmetrical up and down, and the head can be adjusted when the lower part is worn; the crushing tooth plate of the large jaw crusher is designed to be symmetrical to each other. The crushing plate can be replaced and used after wear. The material selection of the crushing tooth plate, in order to improve the service life of the crushing plate, the material is manganese steel with more than 12% manganese, and ZGMn13 is commonly used. The toughness of manganese steel is better, although the hardness is not high (about 210 HB), but because it has the characteristics of cold work hardening, it will continue to be strengthened under pressure, so it will continue to wear and strengthen during work until it is worn out. Use it to be scrapped. At present, many new materials have appeared on the market, such as ZGMn13Cr2 and other multi-alloy composite materials. Although these materials are relatively expensive, their service life is several times that of ordinary manganese steel parts. After casting, the manganese steel broken tooth plate must be treated with water toughening. The operation of the water toughening treatment is basically the same as that of quenching, that is, the cast manganese steel broken tooth plate is heated to 1 000~1 100 ℃ and then rapidly cooled in water. After water toughening treatment, a uniform metallographic structure can be obtained, and the metallographic structure can be fixed, avoiding the deterioration of performance due to the natural phase change during use.
