The jaw plate or jaw dies is the main wear part of the jaw crusher. A set of jaw plates usually consists of two parts: the movable jaw plate and the fixed jaw plate. During the operation of the jaw crusher, the movable jaw plate attaches to the movable jaw to perform a complex swinging motion, forming an angle with the fixed jaw plate to squeeze the stone. The crushing cavity, composed of the movable jaw and the fixed jaw, simulates the movement of animal jaws, enabling the jaw crusher to complete the crushing operation of materials.

Depending on the model of the jaw crusher, there are various sizes of jaw plate available. The jaw plates are made of new high manganese steel, ultra-high manganese steel, super strong high manganese steel, and other materials, suitable for jaw crushers of various specifications.

The jaw plate is the most consumed parts in the use of crushers. Therefore, it is necessary to control quality. In other words, the quality of a jaw crusher is actually determined by the service life of the jaw plate. The jaw crusher casing is generally not easily damaged.

Working Principle Of Jaw Plate

During operation, the wear rate of the upper and lower parts of the crush jaw plate is different, with the lower part wearing out faster. The crusher jaw plate directly contacts the material and bears tremendous crushing force and friction during the operation of the jaw crusher. The service life of the crusher jaw plate directly affects the working efficiency and production cost of the jaw crusher. Therefore, it is particularly important to extend the service life of the jaw crusher’s crushing plate. Strengthening the service life of the crush plate of the jaw crusher can be considered from aspects such as design, material selection, assembly, and improvements in the use process.
