Jaw crusher has wide applications and it is a kind of fine crushing equipment used in severe working condition. Customers should maintain and check jaw crusher regularly, and eliminate the problems timely. But how can we assess the problems accurately and eliminate them? In this article, we introduce frequent problems and solutions in jaw crusher work process.

Problems And Solutions In Jaw Crusher

Problem: there is metal clashes or jaw plates vibration

Solution: this is because the jaw plates loosen or the fixed bolts loosen or part. To solve this problem, operators should tighten or change them timely.

Problem: the toggle plate parts frequently

Solution: The toggle plate not only transfers the driving force but also protects the jaw crusher because of its lower strength. The toggle plate parts because it cannot overcome the force produced by crushing and also might because of the pressure from the spring. To solve this problem, the operator should loosen the spring in a proper degree.

Problem: when the jaw crusher is idling, there is metal clash in the lower part

Solution: There might be three reasons about this problem. The first one is because the discharge opening is too narrow leads to the collision of movable jaw plate and fixed jaw plate. To solve this problem, operators should adjust the discharge opening size timely. The second reason is that the sound is from the supporting device of toggle plate or the gasket adjustment device. It is because that the movable jaw plate, the toggle plate and the main body are not tightly compact, which makes the head of toggle plate clashes the supporting device or the gasket adjusting device. The operator should tighten up the nut until the sound disappears. The last reason might be that the supporting slider of toggle plate wears or loosens badly. The operator should change the slider.

Problem: the final products size increases

Solution: this is because the lower part of jaw plates wear badly. To solve this problem, operators should change the side of jaw plates or replace them with new ones.

Problem: jaw crusher stop working, but the flywheel gyrates

Solution: this is because the spring in the tie rod or the tie rod itself broken, or the toggle plate parts. To solve this problem, operators should change the broken parts.

In the production process of jaw crusher, operators should maintain it regularly, especially for the main crushing parts to reduce the chances of these problems.
