The tooth plate is the main Raymond Mill Grinding Plant For Talc working component of the jaw crusher. In the process of crushing the material, the material is severely ground and violently impacted. The life of the tooth plate has always been a problem of engineering concern, so increasing the service life of the tooth plate has become a An important research topic. The degree of wear of the tooth plate is related to the physical and mechanical characteristics of the crushed material, the structure of the tooth plate, the use parameters of the crusher, and the kinematics. It depends largely on the movement trajectory of the movable jaw tooth plate. The following analyzes the impact of the tooth trajectory of the compound pendulum jaw crusher on the life of the tooth plate, and several measures to improve the wear of the tooth plate to increase the service life of the tooth plate.
1. The influence of the Vertical Roller Mill Production Process movement path of the tooth plate on the life of the tooth plate. The degree of wear of the movable jaw tooth plate is not only related to the physical and mechanical properties of the crushed material, the shape of the tooth plate, the crusher use parameters and other factors, but also closely related to the movement trajectory of the tooth plate. The movement trajectory is different, and the degree of wear of the tooth plate is also different. At different heights of the crushing cavity, the trajectories of the points on the tooth plate surface vary greatly. In the upper part of the crushing cavity, the motion path of the tooth plate is an approximate ellipse, while in the lower part of the crushing cavity, the motion path of the tooth plate is an extreme ellipse. The motion characteristic value of the moving end of the discharge end of the compound pendulum jaw crusher is large, that is, the vertical stroke is large, which is extremely beneficial to the discharge, especially the discharge of viscous and wet materials, but the vertical stroke is large, and the material is here Long sliding time will cause the abrasion of the tooth plate to increase here. The holding part is near the discharge port. When the movable jaw is closed, there is an upward movement component. This component causes greater friction between the material and the tooth plate. , Resulting in over-crushing of the crushed product, and the material wear on the tooth plate is more and more serious. In order to improve the wear of the moving jaw tooth plate and increase the service life of the tooth plate, in addition to selecting the more suitable design of the tooth plate shape and printing the better parameters, it is more important to control the size and wear of the tooth plate by changing the movement track of the moving jaw characteristic.
