Jaw crusher is specially used to crush large pieces of materials. The working environment is extremely harsh and the requirements for the machine are relatively high.

　Common wearing parts of jaw crusher mainly include movable jaw plate, fixed jaw plate (the materials they crush are different, and the service life and wear degree are also different. Limestone can generally be used for more than 2 years, and hard materials such as granite can be used for half a year to one year.), guard plate (the side guard plate of jaw crusher is used to protect the shell from wear. The wear speed varies according to the different materials being crushed. It must be replaced in time when it is severely worn or broken.), elbow plate (the elbow plate has two functions, one is to push the movable jaw head to work and crush stones, and the other is to act as a fuse), bearing (as long as the lubrication and maintenance are proper, the bearing of jaw crusher is not easy to damage. Generally, there is no problem with the life of 3-5 years. The life will be extended with proper maintenance).

　In the actual production process, the 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, the unsatisfactory lubrication effect of the equipment 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, do a good job of repairing and maintaining wearing parts, and strengthen the inspection process. This can also extend the life of the machine.
