[0002] The working part of the jaw crusher is two jaw plates, one is the fixed jaw plate (fixed jaw), which is fixed vertically (or slightly tilted at the upper end) on the front wall of the machine body, and the other is the movable jaw plate (moving jaw), which is inclined and forms a crushing chamber (working chamber) with the fixed jaw plate. The movable jaw plate makes periodic reciprocating motions against the fixed jaw plate, sometimes separating and sometimes approaching. When separated, the material enters the crushing chamber and the finished product is discharged from the bottom; when approaching, the material between the two jaw plates is squeezed, bent and split to be crushed.

[0003] The existing crushing plate of the jaw crusher will suffer serious wear of the strip-shaped toothed portion on the surface of the crushing plate during long-term use, and the crushing plate needs to be replaced. However, due to the different positions of the multiple strip-shaped toothed portions, the wear conditions are also different. Some of the strip-shaped toothed portions can still be used. Replacing the entire crushing plate will result in high maintenance costs and increase the operating costs. Utility Model Content
