Impact Crusher Routine Maintenance

author:dahua1 time:2019-11-11

Running in an outdoor environment near the mine for a long time, the impact crusher will inevitably have some failures. Once the downtime occurs, it will delay the construction period and cause great losses. In order to more effectively overhaul the crusher, we will sum up the following points for you to quickly solve the problem of the impact crusher.

1. Impact crusher start device does not turn

Check whether the material in front of the plate feeder falls into the crushing chamber due to the vibration of the stop, and the material is stuck in the rotor. It is necessary to clean the material in the crushing chamber and restart it after starting up again.

2. Impact crusher broken bearing fever

The bearing should be inspected for good lubrication. Under normal conditions, the lubricant should be filled with 50% of the housing volume. In the other case, the lubricant is degraded and viscous. The bearing needs to be cleaned and replaced with a new one.

3. Equipment vibration is abnormal

It may be that the feed size is too large; the wear parts are unevenly worn, the impact crusher hammer needs to be replaced; the rotor is unbalanced, need to be adjusted, proofreading balance; check whether the equipment anchor bolts are tight and properly reinforced.

4. Impact crusher broken belt flip

Mainly due to the broken belt, the need to replace the V-belt, pay attention to ensure the quality of the belt; or because of the improper assembly of the pulley, the active and driven pulleys should be adjusted on the same plane.

5. The machine bearing is bent or broken

The main reason is that the main engine is overloaded for a long time, the heat treatment of the bearing is improper, and the hardness of the broken material exceeds the standard. When handling, it is necessary to replace the new bearing, and pay attention to timely maintenance and repair during the future operation.

6. The impact crusher appeared boring car

The impact-shock is suddenly stopped during operation, which causes many reasons, such as blockage of the discharge port, slippage of the belt, low voltage, and bearing damage. These problems should be eliminated one by one, such as removing the blockage of the discharge opening, tightening the belt, raising the voltage and ensuring the stability of the voltage, and replacing the bearing.

7. The device spring parts break

The main reason for this failure is that the spring is not relaxed when the discharge opening is adjusted. Therefore, the broken spring must be replaced during processing.

8. The internal noise of the broken cavity

Should stop immediately, check whether the inside of the crushing chamber contains metal impurities or parts break, and clean the crusher cavity; check the internal lining fastening and the gap between the hammer and the lining, too small clearance will cause abnormal noise .

9. Flywheel slewing and crusher do not work

The main reason is that the tie rod spring and the tie rod are damaged, the pull rod nut is tripped to release the bracket from the support slider, or the bracket is broken and broken, and the reason should be checked to replace the damaged component.

10. There is glue smell in the operation of the equipment.

The main cause of this problem is that the belt slips, the friction with the pulley produces a pungent rubber smell, or the rotor is stuck. It is necessary to check the rotor in the machine cavity and solve it in time.

11. The discharge granularity is too large

Explain that the impact-shock crusher hammer or Impact crusher lining is seriously worn, causing the gap between the hammer and the Impact crusher plate to be too large, adjusting the back-and-forth impact frame clearance, or replacing the lining plate and the plate hammer; adjusting the position of the Impact crusher frame so that the sides and the machine The gap between the lining plates is even; if the lining on the frame is seriously worn, it should be replaced in time.
