The solution to the no-load failure of the jaw crusher

Before the jaw crusher is officially put into production, users need to test it for no-load operation. During no-load operation, it is a relatively common phenomenon that metal impact sounds appear in the lower part. In view of this phenomenon, we combined the actual situation of the operation and summarized the following four reasons and solutions for the no-load failure of the jaw crusher:

1. The tooth plates of the movable jaw and the fixed jaw collide with each other: the metal impact sound caused by this situation is caused by the ore discharge opening being too small, so the user should adjust the size of the ore discharge opening in time.

2. The side liner and tooth plate (moving and fixed) of the crushing chamber are loose: the user should fasten them in time and replace them if necessary.

3. There is a problem in the support of the thrust plate or the gasket adjustment device: this phenomenon is generally due to the disappearance or damage of the elasticity of the buffer spring of the pull rod, or the spring is not pressed tightly to cause rotation. When the toggle plate of the movable jaw plate is combined with the body If it is not tight, the bracket head will collide with the supports at both ends, or the adjusting gaskets will collide with each other. The compression nut should be tightened in time until the impact sound disappears.

4. Severe wear of the toggle support slider: When the toggle support slider is severely worn or loose, there may also be a knocking sound. Therefore, when the toggle head is severely worn, it should be replaced to reduce the occurrence of failures. probability.
