Causes and Solutions of Abnormal Vibration of Jaw Crusher

The abnormal vibration of the fuselage of the jaw crusher in the process of crushing will affect the normal crushing of the jaw crusher and even reduce the service life of the equipment, so the problem of excessive vibration and abnormal vibration of the body must be solved.

Reasons:

The abnormal vibration of the jaw crusher's fuselage should first be found, so as to prevent and avoid unnecessary losses.

1. The underpin bolts of Jaw crusher are not properly fixed or loosen during operation;

2. Under the working condition of jaw crusher, the bearing clearance is unreasonable or the bearing is damaged;

3. Spindle bends severely;

4. The movement of the moving jaw is too large.

Solutions:

The vibration of jaw crusher fuselage increases the impact of thrust plate on the adjusting seat and makes the foundation have great vibration linkage effect, which will speed up the wear of the thrust plate and the thrust plate cushion.

1. Check the firmness of the foundation bolts, and when loosening is found, tighten it in time;

2. Check the bearing clearance, adjust to the appropriate clearance, and replace the new bearing parts if the bearing is damaged;

3. If the spindle is deformed, replace the new spindle directly;

4. To reduce the oscillating pressure of the jaw, a conveyor belt with the same size as the adjusting plate can be added as a cushion between the adjusting plates to weaken the vibration in a certain range. But in this way, the adjusting plate is easy to escape, so it is necessary to weld two pressure plates to prevent the adjusting plate from escaping.
