The jaw crushing motor jaw cannot swing

The jaw crusher mainly relies on the jaw plate to crush the ore, the jaw plate of the jaw crusher is divided into the moving jaw and the fixed jaw, the moving jaw is able to move, which plays an important role in the crushing of materials, some users report the phenomenon that the moving jaw cannot swing in the process of use, why?

In the jaw crusher working process, if you hear a violent sound, moving jaw plate will appear to stop swinging phenomenon.The problems that cause the jaw to break and the jaw cannot swing mainly include the flywheel turning, the connecting rod swinging and the tie rod spring becoming slack, which will cause the jaw to stop swinging.


1. Common reasons

Jaw crusher broken mobile jaw can't swing, within the common reason is equipment falls into the broken objects, is other irrelevant materials, broken the thrust plate damage or rivet fracture occurs, if the damaging causes that the lower part of connecting rod, mainly because of lower part of connecting rod installation thrust plate support cracks developed in the groove of the slider.Therefore, without proper calculation during installation, the movable jaw will not swing.

2. Friction component temperature

Friction component temperature of jaw crusher.Jaw crusher in high-speed operation, because of friction power consumption, all into heat, causing the temperature of friction components to rise.When using lubricating oil for lubrication, constantly absorb heat from the friction surface to be distributed, or provide a certain amount of oil will be tropical, so that the temperature of the friction surface decreases.Moving jaw temperature.The jaw crusher crushes the material by using the up and down action of the jaw plate repeatedly, the upper and lower parts of the moving jaw are close to the fixed jaw plate, after crushing the material, the moving jaw leaves the fixed jaw, and the product is discharged from the discharge port.It can be seen that the working intensity of the moving jaw is high, and the temperature of the moving jaw is easy to appear abnormal. When the temperature rises to a certain limit, the damage of the jaw plate will be caused. When necessary, some measures should be taken to solve the abnormal temperature rise of the moving jaw, to avoid the shutdown caused by equipment failure and reduce the production benefit.

3. Work in high temperatures

Jaw crusher in high temperature work, should always pay attention to the temperature of the bearing, make it maintain a good lubrication state, and pay attention to sound and vibration are not abnormal.If it is found to be abnormal, stop immediately to check the cause and confirm whether it is stuck by non-breakable objects or whether the hammer head and other parts are damaged.
