Factors influencing wear of mandibular broken plate
Author:xixi Addtime:2019-02-11 Click:
1. Hardness of material
The hardness of the material has an important effect on the wear of the jaw plate. Under the same conditions, the materials with high hardness are easier to press into the surface of the jaw substrate than those with lower hardness, resulting in ploughing wear.
2, Jaw plate material
The wear resistance of jaw plate material directly determines the service life of jaw plate. Although high manganese steel is replaced by other steels under low stress and medium stress impact abrasive wear conditions, it still occupies an important position in wear resistant materials because of its low requirement of production technology and wide source of raw materials.
3. Moving jaw track
The trajectory of moving jaw has an important effect on the performance of jaw crusher. The production capacity of jaw crusher, specific power consumption, steel consumption (jaw wear) and the quality of broken products are all directly related to the track of movement. Taking the compound pendulum jaw crusher as an example, the jaw plate of the compound pendulum jaw crusher usually has the following wear characteristics after being used in production: the wear of the fixed jaw is mainly in the lower part of the jaw plate, the biggest wear is at the discharge mouth, and the biggest wear is at the middle part of the movable jaw plate.
In addition, the gnawing angle and the tooth form also have certain influence on the wear of the jaw plate.
