The working mechanism of jaw crusher

The working mechanism, which is crushing cavity, of jaw crusher is formed by a fixed jaw and a mobile jaw. On both jaw plates, there are lining boards made of manganese steel and they are fixed onto the jaw plate with bolts and wedge. As lining boards directly participate in the crushing process, to improve the crushing effect, on the surface of the lining boards, there are horizontal ripples which are set opposite each other in lumps and bumps. At present, the tooth form of jaw crusher China is triangle or trapezoid on which there are vertical bars. With the application and development of computer technology, the design of tooth form has developed from traditional test method and experience method to applying computer for optimized design, thus gaining optimum crushing effect.
As the abrasion of all the parts of the lining boards in the crushing process is pretty uneven, especially that bottom part near the discharging mouth, lining board is usually made transversely zygomophic, so that it can be reused reversely after the lower part is abraded to extend its service life which is a little different from cone crusher. The lining boards of large jaw crusher China are composed of many blocks which are all interchangeable; with the purpose of prolong its service life.
