Crusher industry's major markets include the chemical, mining, construction, water conservancy, metallurgy, coal, glass and so on. Among of them, cement industry and mining industry account jaw crusher application market  for about 30% respectively.

Jaw crusher is often used in crushing stone, but inadequate preparation before jaw crusher operating will affect the production, even in severe cases, could make the crusher  damage during using and cause  a major overhaul or re-purchase, which  is undoubtedly a great loss for the enterprise. In fact, the following four aspects of preparation work can reduce the risk of machine failure to a certain extent.

There are many China jaw crusher manufacturers. And the types are various from   troditional machines such as jaw crusher, impact crusher, hammer crusher, Roll crusher, etc, to the improvement machine for example, cone crusher. The mining machine is always in constantly improving and updating. However, the widest application is jaw crusher. Whether sand making line or stone crushing quarry, without exception, they all use jaw crusher.It is the necessary equipment for aggregate production line. At present, jaw crusher has developed and some new models are able to do coarse crushing, medium crushing and fine crushing.

1.what should we do if Jaw crusher shutdown suddenly (old saying is machine holding)?

(1) Clean clogging materials at discharge port to guarantee discharge smoothly.

(2) Adjust V-belt tightly or replace V-belt;

(3) Reinstall or replace bush fixing;

(4) Regulate voltage of operation site conforming to main engine voltage requirement.

(5) Replace bearing.

2.Why does the jaw plate give out jumping sound when in operation?

(1) Please fix tight bolts;

(2) Please adjust discharge port to guarantee gap between two jaw plates is correct.

3. Why is the jaw crusher output not able to reach the leaving factory standard?

(1) Replace or increase jaw crusher;

(2) Change motor junction;

(3) Adjust discharge port to the machine instruction statement. Increase fine crushing machine.

(4) Please check if toothed plate and pitch size up to standard, if not, you shall replace jaw plate, adjust relative position between fixed jaw plate and movable jaw plate. Guarantee that tooth is against the root tooth. And fix them tightly to prevent displacement;

(5) Regulate voltage higher at operation site to fit for host motor heavy load requirement.

(6) Replace bearing or movable jaw plate.
