The last article called What are the main components of the jaw crusher briefly introduced the jaw crusher structure can be composed of crushing cavity, moving parts, frame parts,bearing and tooth plate. Then, this article introduces the crushing cavity of jaw crusher and its structural characteristics in detail.
The crushing cavity of jaw crusher is composed of fixed jaw and movable jaw. Both jaw plates are lined with manganese steel lining plates, which are fixed on the jaw plates with bolts and wedges. Because it is directly involved in crushing, in order to improve the crushing effect, the surface of the lining board has longitudinal ripples, and the unevenness is opposed. At present, the tooth shape of the lining plate of the domestic jaw crusher is mostly triangular and trapezoidal, and its surface is vertical and straight. With the application and development of the computer, the design of the tooth shape has developed from the traditional test method and empirical method to the use of the computer to optimize the design, so as to obtain the best crushing effect.
The crushing cavity structure of the jaw crusher is a very important part of the equipment body. Due to the uneven wear of the various parts of the lining board during crushing, especially the lower part near the discharge port, the lining is generally made up and down symmetrically. After the lower part is worn, inverting it can extend the service life.
