5. Install the New Grinding Ring:

- Carefully place the new grinding ring into the designated position in the mill, ensuring it is properly aligned.

- Secure the new grinding ring in place by tightening the bolts or fasteners to the manufacturer's recommended torque specifications.

6. Apply Lubricant:

- Apply a small amount of grease or lubricant to the contact surfaces between the grinding ring and other components to reduce friction and ensure smooth operation.

7. Reassemble the Mill:

- Reassemble any housing or cover that was removed to access the grinding ring assembly. Make sure all components are securely fastened.

8. Test the Raymond Mill:

- Power on the Raymond mill and run a test to ensure that the new grinding ring is properly installed and functioning correctly.

- Monitor the operation of the mill for any unusual noises, vibrations, or issues that may indicate a problem with the replacement.

By following these steps and ensuring proper installation of the new grinding ring in your Raymond mill, you can help prolong the life of the equipment, maintain efficiency, and prevent potential issues during operation. If you are unsure or inexperienced with this process, consider seeking assistance from a qualified technician or the manufacturer for guidance.

Replacement frequency

1. Generally, it is necessary to replace the grinding ring once and the grinding roller twice.
2. When the wear degree of the grinding ring is greater than 2cm, it must be replaced, otherwise the efficiency of the air duct will be seriously affected, and the air duct panel is expensive, and replacement is more troublesome.
