Detailed Analysis Of Installation Principle And Size Of Jaw Crusher

Last Update:2020-05-13 15:05:24

The main wearing parts of the jaw crusher are the moving and fixed jaw plates, which are usually made of high manganese steel. The section is generally tooth shaped, so it is called the tooth plate in production. In fact, the installation principle of jaw crusher is relatively complex. The crushing mechanism is mainly achieved by the continuous crushing of materials by the mutual extrusion of moving jaw relative to fixed jaw. In this process, the wear of jaw plate is very serious. So what are the causes of jaw plate wear in jaw crusher installation process?

In fact, the installation process of jaw crusher is relatively complex. The common wear part in the equipment is the jaw plate, especially the wear at the middle and lower third of the jaw plate is actually serious, while the wear at the upper part of the jaw plate is generally not much. Once the tooth profile of the jaw plate is ground, it will lose the corresponding working capacity, which has a great impact on the overall production efficiency. The installation size of jaw crusher is relatively strict. Through SEM observation, the concave and convex parts of the gear plate after wear can be seen.

Through the installation principle of jaw crusher, we can see that in fact, the dynamic and static jaw plate wear is relatively common, but if there is wear in a short time, even if it is failure, this is abnormal. This kind of wear is mainly caused by the properties of materials, including the hardness of materials, feed particle size, density, etc. at the same time, the operator did not make timely adjustment, so if the production continues, it will lead to more serious wear of the jaw plate and affect the production efficiency.

The installation dimension of jaw crusher is very strict. There is a certain angle between movable jaw plate and fixed jaw plate. If the angle exceeds the normal range, the jaw plate will be worn. Generally speaking, if the rotating speed of eccentric shaft is too fast, the number of swing of the moving jaw will increase continuously. At this time, the materials that have been broken can not be discharged in time, resulting in the blockage of the crushing chamber, which will accelerate the wear of the jaw plate and seriously affect the production quality.

The installation process of jaw crusher is complex, and the reasons for the wear of jaw plate are actually various. The above briefly introduces several common wear reasons, hoping to bring substantial help to the majority of users. It is also suggested that all operators should understand the installation principle and operation skills of jaw crusher in the process of production, so as to ensure the ideal production efficiency and normal operation of the equipment.
