The automated system is equipped with high-precision weighing sensors and PLC intelligent proportioning control. The batching error can be controlled within ±0.5%, precisely controlling the input of nitrogen, phosphorus, potassium raw materials and additives to ensure uniform fertilizer nutrients, compliance with national standards, significantly reducing the finished product defect rate, and improving product quality control and market competitiveness. The entire process—feeding, batching, mixing, screening, packaging, and palletizing—is interconnected without manual intervention, enabling 24-hour continuous operation. The hourly output of a single line increases by more than 30%, while reducing front-line operators by 60%-80%, significantly reducing labor costs. Precise batching also avoids raw material waste, increasing raw material utilization to over 99%.

The system is equipped with real-time data monitoring, fault early warning, and automatic shutdown functions. It monitors the operating parameters of the NPK bulk blending machine throughout the entire process, promptly alerting to any abnormalities to prevent operation with malfunctions, reduce equipment damage caused by human error, extend equipment life, lower maintenance costs, and ensure stable production line operation. Simultaneously, the entire production process data can be recorded and traced, meeting the traceability requirements of the agricultural input market and enhancing the company's brand credibility.

Furthermore, the automated production line operates in a closed system, reducing dust emissions, improving workshop conditions, and keeping personnel away from high-speed operating equipment, thus reducing the risk of safety accidents from the source. The PLC control system can quickly store and switch formula parameters, enabling one-click customized product production, significantly improving the production line's formula adaptability to meet the blended fertilizer needs of different regions and crops.
