The reasons for the decline in output of pig manure organic fertilizer production line during operation may involve multiple aspects. The following are some common reasons and solutions:

1. Insufficient equipment maintenance: After long-term operation of the equipment, problems such as component wear and looseness may occur. Regularly check the various components of the organic fertilizer equipment, especially the wearing parts such as screens and claws, and replace the severely worn parts in time. Regularly add lubricating oil to ensure smooth operation of the equipment.

2. Raw material problems: impurities such as metal and stone mixed in the raw materials will affect the efficiency of equipment such as crushers and even damage the equipment. Before the raw materials enter the production line, they should be strictly screened to remove impurities.

3. Improper adjustment of process parameters: If the equipment speed is not adjusted according to the requirements of the manual, it may lead to a decrease in output. Ensure that the equipment speed is within the rated range. If the temperature, humidity, ventilation and other parameters are not well controlled during the fermentation process, it will affect the fermentation efficiency. Regularly monitor the fermentation parameters and adjust them in time.

4. Environmental factors: Ambient temperature and humidity have a great impact on the fermentation and drying links. Ensure that the production environment meets the equipment operation requirements.

5. Improper operation: Operators are not familiar with the equipment operation process or improper operation may lead to low equipment operation efficiency. Train operators to ensure that they are familiar with the equipment operation procedures.

6. Equipment aging: The equipment has been used for too long and its performance has declined. Regularly evaluate the equipment status and update it when necessary.

Through the above measures, the problem of reduced output of pig manure organic fertilizer production line can be effectively investigated and solved, and production efficiency and product quality can be improved.
