长时间在矿山附近的室外环境中运行，Long time running in the outdoor environment near the mine, the impact crusher will inevitably have some failures. Once the fault is shut down, it will delay the construction period and cause great losses. In order to repair the crusher more efficiently, the editor summarizes the following points for you to quickly "prescribe the right medicine" and solve the problems of the impact crusher in time.

1. Counterattack and break the startup device without turning

Check whether the material in front of the plate feeder falls into the crushing cavity due to the shutdown vibration, causing the material to jam the rotor. The material in the crushing cavity needs to be cleaned, and the solution can be solved by restarting the machine.

2. Counterattack and break the bearing heat

The lubrication of the bearing should be checked for good condition. Under normal circumstances, the lubricating oil should be filled with 50% of the bearing housing volume; another situation is that the lubricating oil is deteriorated and thick, and the bearing needs to be cleaned and replaced with new lubricating oil.

3. Abnormal equipment vibration

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

4. Counterattack broken belt flip

The main reason is that the belt is damaged and the V-belt needs to be replaced. Pay attention to ensuring the quality of the belt; or because of the improper assembly of the pulley, the driving and driven pulleys need to be adjusted on the same plane.

5. The machine bearing is bent or broken

The main reasons are long-term overload operation of the main engine, improper heat treatment of the bearing, and excessive hardness of the crushed material. When handling, it is necessary to replace the new bearing, and pay attention to timely maintenance and repair in the future operation process.

6. The counterattack crusher appears stuffy

The counterattack suddenly stops during operation. There are many reasons for this failure, such as blockage of the discharge port, belt slippage, low voltage, and bearing damage. Deal with these problems one by one, such as clearing the blockage of the discharge port, tightening the belt, increasing the voltage and ensuring the stability of the voltage, replacing the bearing, etc.

7. The spring parts of the equipment are broken

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

8. Abnormal noise inside the crushing cavity

Stop the machine immediately, check whether there are metal impurities or broken parts in the crushing cavity, and clean the crusher cavity; check the tightness of the inner liner and the gap between the hammer and the liner. If the gap is too small, it will also cause abnormal noise. .

9. Flywheel rotation and crusher do not work

The main reason is that the tie rod spring and tie rod are damaged, the tie rod nut trips to cause the toggle plate to escape from the supporting slider, or the toggle plate breaks off and falls off. The cause should be investigated and the damaged parts should be replaced and installed.

10. Gummy smell during equipment operation

The main reason for this problem is that the belt slips, the friction and heat generated by the belt pulley give off 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

It means that the impact crusher's plate hammer or impact liner is severely worn, causing the gap between the impact plate and the impact plate to be too large. Adjust the front and rear impact frame gaps, or replace the liner and blow plate; adjust the position of the impact frame so that both sides and the machine The gap between the frame linings is uniform; if the linings on the frame are severely worn, they should be replaced in time.
