Jaw crusher has two jaw plates, one is fixing jaw plate, the other is swing jaw plate, in which the swing jaw plate is the main moving part. It plays the main role in crushing materials. If the swing jaw does not move during operation, it will inevitably influence the working condition of the whole machine. Luoyang Dahua based on the rich experiences analyzing this phenomenon to find the fault reason and put forward the solution.
During operation of jaw crusher, if we hear harsh split noise, the swing jaw plate will be stopped. This may be caused by the flywheel rotating, the connecting rod swinging, or the pull-rod spring loose. According to the practical experience, the common reason is that the non-crushed materials entering into the crushing cavity, which damage the thrust plate or the rivets are broken. If the bottom of connecting rod is broken, may be the groove of the sliding block on the thrust plate is split. Or before installation, the safety thrusting force is not correctly calculated.
If appeared the above problem, should stop the crusher, loose the nut, take out the pull-rod spring, hang the swing jaw plate, check the sliding cover of thrust plate, and finally replace the thrust plate. For the connecting rod, directly replace the new one or repair.
