Extending the life of a twin-screw granulator requires attention to a number of key aspects, including proper operation, regular maintenance, and proper care. Here are some suggestions:

1. correct operation:
   - Follow the operating manuals and guidelines provided by the manufacturer to ensure that the twin-screw granulator is operated under the correct operating parameters.
   - Avoid overloading and unreasonable operating conditions to prevent unnecessary stress and wear on the equipment.

2. regular maintenance:
   - Establish a regular maintenance program that includes cleaning, lubrication, and parts inspection.
   - Regularly inspect screws, dies, motors and other critical parts for wear and replace worn parts in a timely manner.

3. cleaning and lubrication:
   - Regularly clean the residues in the screw, die head and barrel to prevent accumulation that will affect the working efficiency.
   - Maintain good lubrication and use proper lubricant to minimize friction and wear.

4. Temperature control:
   - Control the processing temperature within the recommended range to avoid excessive temperature damage to equipment parts.

5. Avoid no-load operation:
   - Avoid no-load operation as much as possible, i.e., let the screw rotate without raw material to minimize unnecessary wear and tear.

6. Repair faults in time:
   - If any fault or abnormality is found, stop the machine and repair it in time to avoid the fault expanding and affecting other parts.

7. Regular inspection of the electrical system:
   - Regular inspection of the electrical system to ensure the normal operation of the electrical parts to prevent equipment failure due to electrical problems.

8. Employee training:
   - Train operators to understand the correct operating procedures and equipment maintenance methods to improve the efficiency and life of the equipment.

9. Regular inspection of the cooling system:
   - If the equipment is equipped with a cooling system, regularly check the operation of the cooling system to ensure that the equipment maintains the proper temperature during normal operation.

10. Purchase high-quality raw materials:
    - The use of high-quality raw materials will help reduce wear and tear on the equipment and extend its service life.

By taking these factors into consideration, the service life of the twin-screw granulator can be effectively extended, and the stability and productivity of the equipment can be improved.
