In the entire stone production line, jaw crushers are generally used as primary crushing equipment. Among all mining crushing machinery, jaw crushers are also crushers with a wide range of applications.
Jaw crusher is comm known as jaw crusher, also known as tiger mouth. The crushing chamber is composed of two jaw plates, a movable jaw and a static jaw. It is a crusher that simulates the movement of the two jaws of an animal to the material crushing operation. It is widely used in the medium-size crushing of various mines and bulk materials in the mining, smelting, building materials, highway, iron ore, water conservancy and chemical industries. The compressive strength of the crushed material can reach 320Mpa.
We all know that the crushing equipment has a certain service life, especially the tooth plate of the jaw crusher is a part that is very easy to wear and needs to be replaced regularly. So what are the reasons for the wear of the jaw crusher? The jaw crusher tooth plate is made of standard high manganese steel treated with water toughening. The tooth plate wear is cutting wear. After analysis, this kind of cutting wear is mainly divided into three situations:
1. The short-distance sliding friction of the material relative to the tooth plate, friction and cutting the tooth plate to form debris, causing the tooth plate to wear.
2. The material repeatedly squeezes and cuts the tooth plate, and small cracks are formed on the surface of the tooth plate or the root of the protruding part of the tooth plate. These small cracks continue to expand to connect, causing the surface of the tooth plate to fall off and form debris.
3. The material is repeatedly squeezed, causing the surface material of the tooth plate to be partially fractured or turned up, and the broken or turned up part will fall off with the material hit by the squeeze to form debris.
Therefore, to control the wear of the tooth plate of the jaw crusher and to extend the service life of the tooth plate, the hardness and toughness of the tooth plate material are mainly considered. The dental plate has high hardness, strong abrasion resistance and strong anti-extrusion ability, which reduces the brittle fracture of the dental plate in the process of crushing and collision with the crushed material, and reduces the deformation and cracking of the dental plate surface.
Jaw crusher tooth plates are easy to wear parts. In order to improve production efficiency, it is necessary to replace jaw crusher tooth plates regularly. At the same time, the manufacturers of dental plates continue to increase scientific research investment, improve the structure of the dental plates, reduce the sliding friction between the material and the dental plates, reduce the amount of cutting wear, thereby prolong the service life of the dental plates, and bring practical results to customers Economic benefits.
