What is the reason for the fast wear of jaw crusher tooth plate

In the entire stone production line, the jaw crusher is generally used as a primary crushing equipment. Among all mining crushing machinery, the jaw crusher is also a crusher with a wider range of applications.

Jaw crusher is commonly 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 animal's jaws to complete 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 crushing equipment has a certain service life, especially the tooth plate of jaw crusher is very easy to wear and need to be replaced regularly. So what are the reasons for the wear of the jaw crusher?

What is the reason for the fast wear of jaw crusher tooth plate
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 causes the friction and cutting of the tooth plate to form debris, which causes 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, the hardness and toughness of the tooth plate material are mainly considered to control the wear of the tooth plate of the jaw crusher and extend the service life of the tooth plate. The tooth plate has high hardness, strong wear resistance, and strong anti-extrusion ability, which reduces the brittle fracture of the tooth plate during the extrusion and impact process of the broken material, and reduces the surface deformation and cracking of the tooth plate.

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 must 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.
