Before jaw crusher put into production, the customer needs to take no-load test to check the crusher. During the test process, jaw crusher will appear the following problems. Aimed at this phenomenon, combined the actual operation situation, Luoyang Dahua summarize the four fault reasons and the solution.
1. The fixed jaw plate and movable jaw plate strike with each other. The sound caused by this phenomenon is due to the small discharging opening, so the customer should adjust the size accordingly.
2. The side liner plate of crushing cavity and the tooth plate (fixed and movable) loose, the customer should tighten in time, or replace the new one if necessary.
3. Thrust plate bearing or the pad adjustment device appears problem. It is caused due to the pull rod buffer spring lose efficacy or be damaged, or does not press the spring. If the movable jaw plate, toggle plate and the machine doesn't contact closely, the toggle plate head will strike the end bearing, or the pad hits each other, the customer should fasten the nuts until the above noise disappear.
4. The sliding block of toggle plate is badly worn. If the sliding block of toggle plate being worn or loose, it is likely to generate striking noise. Therefore, should replace the toggle plate when the head of the toggle plate is worn seriously to reduce the fault probability.
