How to improve the life of jaw plate?
Jaw crusher working mechanism is made up of moving jaw and jaw of the working chamber, moving jaw and jaw bearing huge crushing force and material friction, easy to wear out, in order to protect the jaw plate, generally in the surface of the jaw and jaw wear-resistant lining plate, this lining plate is also known as the crushing plate.  The surface of the broken tooth plate is usually made into a tooth shape. The Angle of the tooth peak of the broken plate is 90° ~ 120°, and its size is determined by the nature and lumpiness of the broken material When crushing large pieces of material, the Angle should be larger;  When breaking small pieces of material, the Angle can be smaller.  The size of the pitch depends on the particle size of the product, usually about equal to the width of the outlet, tooth height and pitch ratio can be 1/2 ~ 1/3.  At work, the broken tooth plate fluctuation two parts wear speed is not the same, lower than the upper wear faster, broken tooth plate in jaw crusher work, direct contact with the material, under a lot of crushing force and material friction role, the service life of the broken tooth plate is directly related to the working efficiency of the jaw crusher and the production cost, therefore, extend the broken tooth plate of jaw crusher  Service life is particularly important.  To prolong the service life of jaw crusher tooth plate can be considered from the aspects of design, material selection, assembly and improvement in the process of use.
