The quality of the jaw crusher depends on the jaw plate of the casting. For jaw crusher equipment, the largest consumption is the jaw plate, so the quality must be checked when selecting materials. The quality of a crusher is actually based on the service life of the jaw plate. The jaw plate is the main casting of the jaw crusher, including the movable jaw plate and the static jaw plate. According to the different jaw crusher models, there are many models and sizes. The jaw plate is made of new high manganese steel, high chromium cast iron, wear-resistant Alloy steel and other materials are suitable for jaw crushers of various specifications. The jaw crusher is composed of a working chamber composed of a movable jaw and a fixed jaw. The movable jaw and the fixed jaw bear huge crushing force and friction of the material, and are easily worn. In order to protect the jaw plate, the movable jaw and the fixed jaw are generally placed between the movable jaw and the fixed jaw. A wear-resistant lining plate is installed on the surface, which is also called a crushing plate. When working, the upper and lower parts of the crushing plate wear at different speeds. The lower part wears faster than the upper part. When the jaw crusher is working, the crushing plate is in direct contact with the material and bears huge crushing force and friction of the material. The service life of the crushing plate is directly related to the working efficiency and production cost of the jaw crusher. Therefore, it is particularly important to extend the service life of the crushing plate of the jaw crusher. Enhancing the service life of jaw crusher castings can be considered from the aspects of design, material selection, assembly and improvement during use.
