Crushed Toothed Plate Part

Jaw plate is the main wear-resistant Crushing Equipment of the jaw crusher: the dynamic jaw plate and the static jaw plate. There are various models and sizes according to the different models of the jaw crusher. The jaw plate is made of new high manganese steel, ultra high manganese steel, ultra strong high manganese steel, and other materials, suitable for various specifications of mineral crushers.

A Rock Crusher is composed of a working chamber composed of a moving jaw and a fixed jaw. The moving jaw and the fixed jaw bear enormous crushing force and material friction, making them easy to wear out. To protect the jaw plate, wear-resistant lining plates are generally installed on the surface of the moving jaw and the fixed jaw, also known as crushing plates. The surface of the crushing plate is usually made into a tooth shape, with the angle of the tooth peak of the crushing plate ranging from 90 ° to 120 °. Its size depends on the nature and size of the crushed material. When crushing large blocks of material, the angle should be larger; When crushing small pieces of material, the angle can be smaller. The size of tooth pitch depends on the particle size of the product, usually taken as approximately equal to the width of the discharge port, and the ratio of tooth height to tooth pitch can be taken as 1/2 to 1/3.

When working, the wear speed of the upper and lower parts of the crushing plate is different. The lower part wears faster than the upper part. When the crushing plate works in the jaw crusher, it directly contacts the material and bears enormous crushing force and material friction. The service life of the crushing plate is directly related to the work efficiency and production cost of the Crushing Machine. Therefore, extending the service life of the crushing plate crusher is particularly important.
