Fault Solutions of Jaw Crusher
Jaw crusher is the main equipment in mining industry with wide application. How to repair the machine fault is of great importance. Now let's talk about it.
¬ Toggle plate break
Fault reason: 1. Overload of main crusher or the material size large than the feeding opening.
2. The non-crushed materials enter into the crushing cavity.
3. It is not parallel between toggle plates.
4. The casting parts have serious casting flaw.
Solution: 1. Replace the toggle plate and control the feeding granularity to prevent overload of crusher.
2. Replace the toggle plate and take measures to prevent the non-crushed materials enter into crusher.
3. Replace the toggle plate and the worn plate pad.
4. Replace the toggle plate with good quality,
¬ Flywheel rotates but the movable jaw does not move
Fault reason1. The toggle plate breaks.
2. The connecting rod damage.
3. The spring break.
Solution: 1. replace toggle plate.
2. Repair connecting rod
3. Replace spring
¬ The products granularity become big
Fault reason: there is obvious abrasion of tooth plate.
Solution: exchange head of the tooth plate or adjust the discharge opening.
¬ Overheat of bearing
Fault reason: 1. it is lack of lubrication grease.
2. The lubrication grease is dirty.
3. The bearing clearance is not suitable or the bearing connection is bad.
4. The bearings damage.
Solution: 1. add sufficient lubrication grease.
2. Clean the bearing and change the grease.
3. Using pad to adjust the bearing tightness or repair bearing base.
4. Replace bearings.
