Reasons for the large wear of the jaw crusher tooth plate
The jaw crusher is composed of two jaw plates, the movable jaw and the static jaw, which form a crushing cavity. It is widely used for medium-sized crushing of various mines and bulk materials in mining, smelting, building materials, highways, iron ore, water conservancy and chemical industries. We all know that crushing equipment has a certain service life, especially the teeth plate of jaw crusher is a part that is particularly easy to wear and needs to be replaced regularly. So what is the reason for such a large amount of wear of the dental plate?
The jaw crusher tooth plate is the raw material of standard high manganese steel treated by water toughening. The wear of the tooth plate is attributed to cutting wear. Through analysis, this cutting wear is mainly divided into three conditions.
1. The material has a short-range sliding conflict with the tooth plate, and the conflicting cutting tooth plate forms debris, which constitutes the wear of the tooth plate.
2. The material repeatedly kneads and cuts the tooth plate, forming fine cracks on the surface of the tooth plate or at the root of the outstanding part of the tooth plate. These small cracks continue to expand to connect, forming the falling of the surface material of the tooth plate, forming broken pieces crumbs.
3. The material is repeatedly kneaded, and the surface material of the tooth plate is partially fractured or turned up, and the broken or turned up part falls off together with the kneaded and impacted material to form debris. Therefore, in order to control the wear of the tooth plate of the jaw crusher and prolong the service life of the tooth plate, the hardness and toughness of the tooth plate material are mainly considered.
The raw material of the tooth plate has high hardness, strong wear resistance and strong anti-kneading ability, which can reduce the brittle fracture of the tooth plate in the process of kneading and impact with the crushed material, and reduce the deformation and cracking of the tooth plate surface.
4. The tooth plate of the jaw crusher is easy to wear. In order to improve the production efficiency, the tooth plate of the jaw crusher needs to be replaced regularly. Manufacturers that produce dental plates should continue to increase investment in scientific research, improve the structure of dental plates, reduce the sliding conflict between materials and dental plates, reduce the amount of cutting wear, and then extend the service life of dental plates, bringing practical experience to customers. economic benefits.
The above is the analysis of the reasons for the wear of jaw crushers. Jaw crushers are generally used as crushing equipment. Among all mine crushing machinery, jaw crushers are also widely used. Hope the above content can be helpful when you use jaw crusher.
