3/20/2015 5:08:12 PM3/20/2015 5:08:12 PM

PE series jaw crusher is mainly used to crush rocks, its jaw plate is easy to be worn and torn after using for a period time. Frequent replacement of jaw plate not only increases the cost of production, but also adds downtime of pe series jaw crusher, affecting the productivity of the machine. So when purchase jaw plates, endure your choice is correct, avoiding premature attrition of pe series jaw crusher’s jaw plate. The following article will provide you a detailed analysis of the selection standard of pe series jaw crusher’s jaw plate.


Analysis from the material of pe series jaw crusher’s jaw plate

1. The hardness of pe series jaw crusher’s jaw plate: due to the hardness of rock is high, so when purchase jaw plate for pe series jaw crusher, the relatively high hardness of jaw plate should be considered first.

2. The toughness of pe series jaw crusher’s jaw plate: when the toughness of pe series jaw crusher’s jaw plate is certain, appropriately increasing the toughness of the jaw plate will not only increase the wear of the jaw plate, but also improve the impact resistance of the jaw plate.

Analysis from the structure of the jaw plate

1. The shape and size of pe series jaw crusher’s movable jaw plate: there are mainly two aspects determining the shape and size of pe series jaw crusher’s jaw plate. One is force suffered by the jaw, and the other is the manufacture and appearance of jaw. The former is the basis ensuring the strength and stiffness of pe series jaw crusher’s jaw plate. According to the jaw structure, we can know that the stress different value of movable jaw’s each cross section should be as small as possible on the promise of the stiffness and hardness requirement of the dangerous cross section.

2. The shape and structure of pe series jaw crusher’s fixed jaw plate: due to the fixed jaw plate bears huge crushing force and friction effect, so it is easy to wear. In order to protect the fixed jaw plate, a layer of wear resistance liner is installed on the surface of jaw plate. This liner is also called crushing plate. The shape of the liner surface likes teeth. The angle of tooth peaks is 90 ° ~120 °, which is determined by the nature and size of the crushed rocks. When pe series jaw crusher is used for crushing huge materials, the angle is big, and when it is used for crushing small size materials, the angle is also small.
