Mining stone processing industry weighs more importance to hammer crusher, impact crusher, cone crusher, jaw crusher, counterattack crusher. So, some failure of crusher machine will influence production process.

Impact crusher description

Impact crusher mainly applies in mining, chemical, building material, and hydroelectric industries. Especially in highway, railway, and hydroelectric industries, impact crusher operation way can change with material type, production scale, and finished material demand.

Impact crusher operation is with stone crushing stone principle for different material types. This kind of machine has high crushing ratio, low energy consumption, and wide application.

Impact crusher failure and maintenance

Impact crusher will have failure under long and bad environment operation. However, impact crusher will influence production period and profits. Common problems are in the following.

1. No-work of machine

Check material clogging and clean them out.

2. Abnormal vibration

Large feeding material, uneven machine wear, imbalance rotor, loose machine base.

3. Overheating of machine bearing

Check lubrication condition of impact crusher bearing parts.

4. Bending and broken of bearing parts

Long-time over loading operation, unreasonable heat handle of bearing parts, excessive hardness of material.

5. Overturn of machine belt

Belt breaking condition and change belt with high quality one. Adjust belt angle into balance level.

6. Machine spring broken

The reason why spring broken is that unloose of spring in narrow discharging gate. So you should change a new spring.

7. Unworked of flywheel

Breaking spring rod makes liner coming off.

8. Blocking run of crusher

Clogging of discharging gate, low voltage, broken bearing parts will cause machine failure.

9. Abnormal noise of crusher chamber

Check chamber with metal or broken parts and clean them.

10. Oversized discharge material

Large wear condition of crusher board hammer and wide gap between board and impact plate should be adjusted or changed.

In maintenance, crusher should be obeyed with these methods for promptly troubleshooting and stable operation.
