Anatomy of Jaw Crusher's wearing parts
Jaw crusher is a commonly used coarse crushing equipment in stone crushing production line, usually used as a head crusher, specializing in crushing large materials, the working environment is extremely harsh, the requirements of the machine is relatively high. The common wearing parts of jaw crusher are movable jaw plate, fixed jaw plate, guard plate, elbow plate, bearing and so on. In the actual production process, the abnormal wear and tear of wearing parts is not only related to the structural defects of the equipment, but also related to the hardness of the material, the size of the material is too coarse, the lubrication effect of the equipment is not ideal, and the environmental factors.
1、Jaw plate
Jaw plate is divided into movable jaw plate and fixed jaw plate, the service life mainly depends on the material and the hardness of the crushed material, crushing of different materials and the degree of wear and tear of the service life is different. The service life and wear degree of crushing different materials are different. Limestone can be used for more than 2 years, granite and other hard materials in half a year to a year.
2、Elbow plate
The role of the elbow plate has 2, one is to push the moving jaw head to do work, crushing stone, one is to play the role of fuse, when into the iron and can not be crushed super-hard materials, through its own fracture to protect the machine from damage.
3, guard plate
Jaw crusher side guard plate is used to protect the shell from wear and tear, according to the crushing of different materials wear rate is different, wear and tear or fracture must be replaced in a timely manner.
4.Bearing
As long as the lubrication and maintenance of proper, jaw crusher bearings are not easy to damage, generally 3-5 years of life is no problem, if the selection of high-end bearings, high level of processing, maintenance and lubrication in a timely manner, the life expectancy can be longer.
How to extend the service life of wearing parts? First of all, we need to use excellent wear-resistant materials to enhance the service life of wearing parts, reduce the user's costs, and secondly, users should standardize the use of crushing equipment, do a good job of overhauling and maintenance of wearing parts, strengthen the inspection process, and find wear and tear in a timely manner to replace, and to prevent the equipment from causing greater damage, and even delay the normal operation of the entire stone crushing production line.
