In the production process of NPK fertilizer production line, the following key matters need to be paid attention to to ensure product quality, production efficiency and environmental protection requirements:

1. Product quality control, moisture control: the moisture content of fertilizer has an important impact on its storage and caking.

2. Particle strength and size: Insufficient particle strength will lead to fragmentation during transportation and storage, increasing the risk of caking. Relatively large particles can reduce the tendency to caking.

3. Production process optimization and ingredient accuracy: ingredient is a key link in the production system, which directly affects product quality and raw material consumption. The instability of manual measurement should be avoided, and automatic measurement equipment should be used.

4. Environmental protection requirements: the exhaust gas of the production line needs to be dedusted, and a cyclone or bag dust collector can be used to ensure that the exhaust gas meets the emission standards.

5. Dust management: Dust generated in the production process should be treated by dry dust removal technology to reduce workshop dust pollution.

6. Equipment and process management: The layout of organic fertilizer equipment should be reasonable to ensure that materials can still flow smoothly when the system is abnormal.

7. Equipment maintenance: Check the wear of the equipment regularly and replace the wearing parts in time to ensure the stable operation of the equipment.

8. Operator quality: operators need to have certain professional skills to meet the stable operation requirements of the production line.

9. Packaging management: Finished fertilizers need to be weighed and packaged by automatic packaging scales to ensure packaging quality.

By strictly controlling the above links, the production efficiency and product quality of the nitrogen, phosphorus and potassium fertilizer production line can be effectively improved, while meeting the requirements of environmental protection and reducing the risks in the production process.
