Jaw crushers specialize in crushing large pieces of materials. The working environment is extremely harsh and the requirements for the machine are relatively high.

　　The common wearing parts of the jaw crusher mainly include the movable jaw plate and the fixed jaw plate (the materials they crush are different, and their service life and degree of wear are also different. Limestone can generally be used for more than 2 years, and hard materials such as granite can be used in half a year to a year. .), guard plate (the side guard plate of the jaw crusher is used to protect the shell from wear. The wear rate is different according to different materials being crushed. It must be replaced in time when the wear is serious or breaks.), toggle plate (the function of the toggle plate There are two, one is to push the movable jaw head to do work and break stones, and the other is to act as a fuse), bearings (as long as they are lubricated and maintained properly, the bearings of the jaw crusher are not easy to damage, and generally have a lifespan of 3-5 years. problem, if maintained properly, the lifespan will be extended).

　　In the actual production process, abnormal wear of wearing parts is not only related to the structural defects of the equipment, but also related to the excessive hardness of the material, the coarse particle size of the material, unsatisfactory equipment lubrication, and environmental factors.

　　If you want to extend the life of wearing parts, you must choose high-quality materials with good wear resistance to enhance the service life of wearing parts. Secondly, you must standardize the use of crushing equipment, perform maintenance of wearing parts, and strengthen inspection procedures. This also extends the life of the machine.
