The simple pendulum jaw crusher crushing chamber is constituted by the fixed jaw (ie, rack anterior) and the movable jaw, in which the fixed jaw plate and movable jaw plate lined with manganese steel made ??of broken plates. Broken plates were fixed with bolts on the front wall of the rack and moving jaw, cut in the lining surface of the friction lining fixed bolt in order to prevent crushing, moving jaw lining the bottom bearing in the bottom of the movable jaw convex stage the upper wedge compression. Lining the bottom of the fixed jaw is supported on a steel plate welded to the rack, the top steel plate pressed.
In order to enhance the crushing effect, the board of the two broken surface with vertical corrugated and convex and concave relative. Thus, in addition to have crushed the ore, as well as bending. Jaw crusher working space on both sides of the walls is also equipped with manganese steel liner. The broken plate wear is uneven, especially in the lower part, near the port of discharge, the greatest wear, often made of broken plates from top to bottom symmetry, so that the lower part of the wear and tear, the inversion of repeated use. The large crusher machine broken board is made by many combination in each block are interchangeable, so you can extend the life of the broken plate.
