To reduce the damage of organic fertilizer production line equipment, the following key measures can be taken:

1. Regular maintenance: Implement regular equipment inspection and preventive maintenance, including cleaning, lubrication, tightening bolts, replacing worn parts, etc. This can timely discover and repair potential problems of the equipment and extend the service life of the equipment.

2. Operation specification training: Provide professional training and skills improvement for operators to ensure that operators are familiar with the correct use and operating procedures of the equipment. Avoid equipment damage caused by improper operation.

3. Avoid overload operation: Use strictly in accordance with the rated load and working capacity of the equipment to avoid overload operation. Overload operation will cause equipment overheating, increased wear, and accelerated equipment damage and failure.

4. Timely cleaning and maintenance of auxiliary equipment: Auxiliary equipment such as conveyor belts and dust removal equipment should also be cleaned and maintained regularly to prevent debris from clogging or wear affecting the normal operation of the main equipment.

5. Proper equipment installation and adjustment: Ensure that the equipment is installed smoothly and reliably, and all parts are adjusted in place. Avoid equipment vibration, increased friction and other problems caused by poor installation or improper adjustment, which will affect the life of the equipment.

6. Implement equipment updates and upgrades: According to the actual wear and tear of the equipment and technical updates, update or upgrade the equipment in a timely manner to improve the performance and stability of the equipment and reduce the risk of failure and damage.

7. Establish a good record and feedback mechanism: Record the equipment's operating data, maintenance records and failure conditions, establish a feedback mechanism and continuous improvement measures, and adjust maintenance strategies and work processes in a timely manner.
