Impact crusher is a kind of crushing equipment widely used in mining, construction, chemical industry and other fields. Due to its frequent use, it often encounters some malfunctions. This article will list some common malfunctions and provide corresponding solutions.
1. Wear of blow bar
The blow bar is one of the important components of the impact crusher. If the blow bar is severely worn, it will not only affect the crushing effect, but also shorten the service life of the equipment.
Solution:
- Replace the blow bar in time to ensure the performance of the equipment.
- Choose a high-quality blow bar to enhance its wear resistance. Commonly used blow bars include high manganese steel blow bars, alloy blow bars, ceramic blow bars, etc.
2. Motor malfunction
The motor is the power source of the impact crusher. If an abnormal phenomenon occurs, it may lead to shutdown of the equipment.
Solution:
- Check whether the motor has short circuit, open circuit, etc.
- Check whether the motor bearing needs to be replaced.
- Check whether the wiring of the motor winding is loose.
3. Discharge port blockage
Discharge port blockage is one of the common malfunctions of impact crusher. If not cleared in time, it will cause equipment shutdown.
Solution:
- Check and clean the debris around the discharge port in time to prevent it from entering the discharge port.
- Modify the installation angle of the equipment to prevent the material from accumulating inside the equipment.
- Replace the screen to avoid poor material screening.
4. Bearing overheating
Bearing overheating will cause unstable operation of the equipment and even burn the bearing.
Solution:
- Check and add lubricating oil in time.
- Check whether the bearing needs to be replaced.
- Reduce the feed amount of the material to avoid excessive load on the equipment.
5. Gear damage
Gears are important components of the impact crusher. Once damaged, they will affect the entire operating system of the equipment.
Solution:
- Replace damaged gears in time.
- Choose high-quality gears to enhance their wear resistance.
- Improve the lubrication and maintenance of the equipment to avoid gear failure due to lack of lubricant.
6. Loose housing screws
Loose housing screws may cause vibration of the equipment, which in turn affects the performance of the equipment.
Solution:
- Check the housing screws regularly to see if they are loose.
- For loose housing screws, tighten them in time.
Conclusion
This article lists some common malfunctions of impact crushers and provides corresponding solutions. During the use of the equipment, timely inspection and maintenance of the equipment can avoid many toubles, thereby increasing the up-time and service life of the equipment.
