In today’s pursuit of precision agriculture, NPK fertilizer production lines, capable of tailoring nitrogen, phosphorus, and potassium ratios to your needs, are becoming the “customization experts” of the fertilizer industry! Like a nutritionist who understands crop needs, they flexibly adjust the ratios of the three core elements, N, P, and K, based on regional soil characteristics and crop growth stages. From a balanced 15-15-15 formula to a high-nitrogen 28-6-6 wheat-specific formulation, they can precisely produce each bag of fertilizer to suit your crop’s needs.

The efficient operation of this production line is inseparable from a set of interconnected professional equipment. In the raw material processing stage, the automatic batching system acts as a precise “weigher”. Through the PLC control system, it automatically weighs urea, monoammonium phosphate, potassium chloride and other raw materials according to the formula ratio, with an error control within ±0.5%. Next, the  double axis mixer  stirs at a speed of 30 revolutions per minute to ensure the uniform blending of the various raw materials and avoid “nutrient gaps”. After that, the  double roller press granulator  or drum granulator takes over, pressing the mixed raw materials into granules with a strength of over 4 Newtons, making them resistant to breakage.After granulation, the three-stage dryer gradually reduces the moisture content of the pellets to below 10%, and then the pellets are quickly cooled to room temperature by the cooler. Finally, the finished product screening machine selects qualified pellets of 2-4 mm. Unqualified pellets are crushed and returned to the furnace. The raw material utilization rate is as high as 98%.

The  NPK fertilizer production line  not only enables flexible formulation customization but also offers intelligent advantages. The entire line can be remotely monitored via a central control system, with one-click start/stop and parameter adjustment, reducing manual intervention and operational errors.
