In the medium and fine crushing of ores, jaw crushers are often used. Among the moving parts of the stone crusher, the lining plate is the part that is in direct contact with the hard material, so it belongs to the wearing part of the crusher accessories. This is also the main reason why it is often necessary to do a good job in the supply of equipment accessories when purchasing equipment. So in the work, to what extent does the lining plate need to be replaced?

The fixed lining plate (tooth plate), the movable jaw lining plate (tooth plate) and the two side lining plates (guard plates) of the jaw crusher are easy to wear and tear, and the particle size of the product will become larger after serious wear. In the initial wear, the tooth plate can be turned around for use, or the upper and lower two pieces can be turned around. The wear of the jaw plate is mostly in the middle and lower parts. When the tooth height is worn out by 3/5, it is necessary to replace the new lining plate. When the linings on both sides are worn out by 2/5, they also need to be replaced with new linings.


As can be seen from the above, when one end of the liner is slightly worn or moderately worn, it can be turned around and adjusted for use, which can make the material used to a large extent, which not only saves the cost of replacing parts, but also plays a good role. . However, when the wear reaches a certain level, it will have an impact on the stability of the product particle size. At this time, it is necessary to replace the accessories in time to better enter a good operating state, which needs to be observed and mastered in time.
