As the fertilizer industry is transforming towards intelligence and refinement, the fully automatic NPK production line has become the core equipment for enterprises to reduce costs and increase efficiency. This production line uses unmanned operation and precise control throughout the entire process to achieve intelligent proportioning of nitrogen, phosphorus, potassium and trace elements, providing a “one-button start” solution for large-scale production of compound fertilizers. ​
Full process automation reduces manual intervention. From raw material storage to finished product storage, the production line realizes equipment linkage through the industrial Internet of Things: the raw materials are transported to the crushing link through the automatic feeding system, and after crushing, they are automatically measured by the intelligent belt scale according to the formula, and then enter the mixed granulation unit through a closed pipeline, without manual handling throughout the process. The central control system integrates data from 12 core links and supports one-button production start. Only 2 operators are required for a single line, reducing labor costs by 80% compared to traditional production lines. ​

Precise proportioning system locks in nutrient balance. Equipped with imported dynamic metering modules, the ratio error of basic raw materials such as nitrogen, phosphorus, and potassium is controlled within ±0.15%, far exceeding the industry standard of ±0.5%. The built-in AI formula library stores 500+ crop-specific solutions. After inputting soil test data, the system can automatically generate the optimal formula. For example, for corn fertilizers for potassium-deficient soils, it can automatically increase the proportion of potassium to 18% and supplement chelated zinc elements to ensure that fertilizer nutrients are highly matched with crop needs. ​
Efficient granulation process improves product quality. The double-axis gravity-free mixer achieves uniform mixing of materials within 3 minutes, with a mixing uniformity of ≥99.8%; the double-roll extrusion granulator is controlled by servo pressure to produce granules with a hardness of 9-12N, and the forming rate is stable at more than 98%. The granules after granulation are screened at multiple levels, and unqualified products are automatically returned for reprocessing. The qualified rate of finished products reaches 99.5%, avoiding waste of raw materials. ​
Intelligent operation and maintenance guarantee reduces the risk of downtime. The equipment is equipped with 20+ sensor monitoring such as vibration, temperature, and pressure. When the bearing temperature is abnormal or the raw materials are in short supply, the system automatically warns and initiates emergency plans – such as suspending feeding and switching to spare raw material warehouses. It supports remote diagnosis function, and engineers can retrieve equipment parameters through the cloud. 80% of faults do not require on-site repair, and the average fault recovery time is shortened to 30 minutes. ​
After a Southeast Asian fertilizer company introduced it, the average daily production capacity of the production line increased to 200 tons, the product nutrient deviation decreased from 1.2% to 0.3%, and the export order volume increased by 40%.
