Pew Jaw Crusher Manufacturer

Pew Jaw Crusher Manufacturer

In the design, dynamic jaw and static jaw crushing plate should tooth peaks of tooth. So, on the material in addition to have broken the extrusion action, and bending function, and the material is easily broken. In order to strengthen the crushing plate, the service life of the small and medium-sized crusher crushing plate design into fluctuation symmetrical shapes, when the lower after wearing adjustable head use; Large mandibles crusher of broken plate design into each other a few pieces of symmetry, to wear after crushing plate exchange use.

materials can choose white cast iron. White cast iron hardness, wear resistance is better, bigger source easy, cheap; Defect is sex crisp, and easier to break, use short life. In order to improve the service life of crushing plate, the material are the more than 12% of manganese steel with manganese better, commonly used is ZGMn13. The toughness of the manganese steel is better, although hardness is not high (about 210 HB), but, because have the characteristics of cold hardening, under the action of the pressure will constantly be improved, therefore, in work wear and strengthen constantly, until wear to can't use was scrapped.

Jaw Crusher Assembly

Assembly, crushing plate must be tightly on board in a, both between should cushion flat, between the crushing plate and jaw plate with a soft metal (such as lead, zinc, etc) as gaskets, and bolt-on. When crusher is working, the crusher plate should be loose phenomenon, if not easy to break off or wear crushing plate, reduce the service life of crushing plate. So, assembly must be installed crushing plate and prolong the service life of the crushing plate.

Troubles in Jaw Crusher Working

In the course of using the improved to strengthen the life span of the crushing plate in the process of production, the broken plate and material direct action, crushing force is very big, especially large stores broken hardness, lead to install the vibration crushing plate bolt, nut, become loose, crushing plate to wear is intensified and produce great noise, serious when broken off the device or break board to shut down, affect the normal production.

In that case, just before starting the tightened bolts, nuts is not completely solve the problem, according to the actual situation of the concrete analysis, trying to adopt practical and feasible method to solve the problem.

For example, can use spring against pine vibration reduction devices solve crushing plate in the work, become loose, so as to extend the service life of crushing plate, improve the work efficiency. Particular way is using the bolt looseness and spring into the tight device, the device by spring in the gland, spring, spring pressure of the cover, the device to wear in the bolt tighten.

the nut, because the spring was nut pressure to a certain degree, they will create strong anti-vibration effect, by a huge breakage force of loose bolts generated by spring a tight force power automatic up, so not bolt looseness and prolong the service life of the crushing plate, improve production efficiency.

In short, in use process can be targeted to specific situation trying to solve specific problems, and prevent the broken loose board, the wear is intensified, break the and so on, so as to extend the service life of crushing plate, reduce the cost, improve the work efficiency.

Conclusion

service life from design select material, assembly, in the process of using improved from the aspects such as, can be very good to strengthen the jaw plate service life, so as to improve the mandibles crusher production efficiency, reduce the production cost.
