Adjusting an impact crusher involves changing the rotor speed, adjusting the gap between the rotor and the impact plate, and adjusting the feed rate. It also involves checking the bearing temperature and lubrication levels. If you need more detailed instructions, I'd be happy to direct you to some helpful resources.
To adjust an impact crusher, follow these steps:
- Inspect the blow bars: Ensure the blow bars are free from any damage and replace if necessary.
- Check the rotor speed: The ideal rotor speed varies based on the size of the blow bars and the desired output size. Verify the rotor speed is set to the recommended RPM.
- Adjust the aprons: The aprons can be adjusted to control the size of the output. Move the aprons closer together to reduce the output size and further apart to increase it.
- Check the clearance between the blow bar and the breaker plate: This clearance should be no more than 3mm. Use shims to adjust the clearance as needed.
- Inspect the drive belt: Ensure the drive belt is tight and properly tensioned.
- Verify the feed size: The feed size should be consistent and match the desired output size. Adjust the feed size as needed.
- Start the crusher and check for any unusual vibrations or noises: Stop the crusher if any issues are detected and troubleshoot the problem before continuing to operate the machine.
These steps can help you properly adjust an impact crusher for optimal performance.
