How To Solve The Wearing Of Jaw Breaker?

Jaw Crusher is a kind of Stone crusher, and jaw crusher is also called Rock crusher. This series of Jaw crushers have many advantages which mainly used in breaking a variety of ore and the medium-size chunk of materials. The Stone jaw crusher can break the compressive strength not more than 320Mpa materials. It can be divided into rough break and small break. We have all specification kinds of the products, and its feedstock size is 125mm-750mm.

In the actual operation.the wearing of jaw crusher is that we must pay more attention.

If the wear and tear is a little bit.just want to restore its geometry,we can turning on the lathe.to make the neck of the shaft to be a right geometry,at the same time to reduce the diameter of the bearing.after some times treatment,if the neck of the shaft has reduced more 5% on the base of original.the is not allowed to turning,it must replace a new one.

The Jaw crusher is working under the huge impact pressure,the babbit liner on the bush have a two year life,when exceed,it need rebuilt.

If the eccentric shaft and bush,heart shaft is wear and tear ,the top distance 1.5 times greater than original,it need to add pad or replaced.

The ore channel wear and tear 1.5 mm,it should rebuild and adjust.

The distance between the top cover of Connecting rod head and the eccentric shaft has a 1.5 times greater than original,it also need add a pad or replace a new one.

When the babbit steel on the bush have deep hole or damage,it should rebuild.

There is a quality requirement for the bush refined:

The color on the surface of the babbitt steel should be silvery white;the Babbitt steel "s surface shouldn"t have ash,sand eye,flaw,contraction cavities


Impact Crusher Has Vital Function in the Breakage


Whether in Sand Making Production Line or Stone Production Line, our aim is to ensure that the impact crusher and jaw crusher can normal operating, in order to extend the crusher life, it is not less process that we should do periodic maintenance to impact crusher in use. Our factory has already made a long idling to various crushers before delivery, in order to reduce fault appear in application process in the future, our customer in new machinery production operation, the worker must do comprehensive examination to impact crusher after production operation, each component tightening, belt transmission is normal, knowing lining board wear, having a cyclical and regular examination.

Stone production line, the first step by Vibrating Feeder supply to Jaw Crusher, then immediately is Impact Crusher, here jaw crusher is playing the role that broken into large materials after impact crusher, meet customer needs 20-60 between particles, using high speed rotating rotor plate hammer, the crushing cavity of into the materials in the produce high-speed impact breakage, and make already broken material along the tangent direction in high into the crushing cavity on the other end of the counterattack board, again being broken, and then to rally from counterattack plate, plate hammer continue repeating the process.

At the same time, in buying impact crusher, we should know what is wearing part, because in broken processlarge material will wear liner, fight back plate, during changing process must follow the principles, first open shelves, removing the attachment bolts from shelf and middle box, then unloaded with wrench twist to flip device hex head parts and then slowly open shelves. In the meaning time, you can use frame above hanging device hanging back frame. Repeat the above process, namely close put on the shelf. Counterattack broken plate hammer wear to certain degree should be timely adjust or change, in order to avoid fasteners with other parts of the damage, causing a greater loss.Jaw crusher and impact crusher have played an important role in the breakage in stone production line. Before problem appears, you should do detailed check, must not carelessness, lest penny wise and pound foolish, causing can not work normally running.
