subject: How To Solve The Common Faults Of Jaw Crusher [print this page] The jaw crusher is a kind of widely used coarse crushing equipment with big inertia force, poor working conditions and heavy-duty work. In order to ensure the normal continuous operation of the jaw crusher, giving full play to its production capacity, except for the proper operation, the regular maintenance and periodic repair is needed for the jaw crusher. In addition, it is a necessary skill for the stuff to find and eliminate the possible failure of jaw crusher accurately and timely. Now Hongxing experts will tell you some common fault and their solutions of jaw crusher.
1. The jaw crusher works with metal percussion and lining jitter. This phenomenon is often caused by the crushing loosening of the chamber side liner and the tooth plate (including the moving plate and the fixed plate) or by the screw loosening or fracturing. It is necessary to firm or replace the loosening part timely.
2. The back brackets crack frequently. The back bracket not only has the function of transferring power, but also plays an insurance role relying on its lacking of intensity. In addition to the low intensity of the bracket central part, its intensity is insufficient to overcome the damage caused by the normal ore crushing force. The crack may be caused by the rod spring weight, coupled with the crushing force. Therefore, at this time, it is better to loosen the spring appropriately.
3. The flywheel turns round and the crusher does not work. This phenomenon is mainly caused by the damage of the tie rod spring or by the crack of the toggle plate. Therefore, it is time to replace and install the broken part.
4. The granularity of the final products turns thicker, which is caused by the severe attrition of the lower part of the crushing lining. At this situation, it is better to swap the upper and lower teeth board or replace a new liner, at the same time, adjust the discharging port to the meet the size demand.
