• 7/5/2020 - Movement trajectory of tooth plate of compound pendulum jaw crusher

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.

• 6/5/2020 - Measures to improve tooth plate wear and increase tooth plate life

In order to improve the wear of the Ore Milling Equipment tooth plate, increase the service life of the tooth plate, and reduce the steel consumption, many engineering and technical personnel have done a lot of research work for it. The measures to improve the wear of the tooth plate and increase the life of the tooth plate are:

Change the positive suspension of the eccentric oil device of the Ore Milling Equipment traditional compound pendulum jaw crusher to negative suspension , Machine weight can be reduced by 20%. Change the downward inclined type of the thrust plate of the traditional compound pendulum jaw crusher to the upward inclined type. , Promote the material to discharge downwards, reduce the blockage, the output can be increased by 20% -40%, the wear of the tooth plate is improved, and the life of the tooth plate can be increased by 2-3 times.

The single-motion jaw of the traditional compound pendulum jaw crusher is changed to a double-motion jaw, so that the longitudinal relative motion between the two movable jaws is close to zero, which eliminates the longitudinal relative motion between the tooth plates from the characteristics of the mechanism movement The service life of the tooth plate can be extended by more than 3 times due to wear, and the economic benefits brought by it are very considerable. We provide full system solutions such as crushing and sand making, and more professional crusher and sand making machine manufacturers.
