The process flow of the compound fertilizer production line includes: raw material ingredients, raw material mixing, raw material granulation, particle drying, granular cooling, particle grading, finished packaging film, and final product packaging.

NPK Compound fertilizer production line is widely applied to produce compound fertilizer with capacity ranging from 5,000-200,000 tons/year. It can granulate NPK, NP, ANP, DAP, MAP, CAN, SSP and other materials into compound fertilizer particles in one processing line.

Compound fertilizer contains two or all three of the basic plant nutrients—Nitrogen, Phosphorus, and Potassium—as well as microelements such as B, Mn, Cu, Zn, and Mo. The raw materials can be powder or bulk, including:

• Small investment, quick profit, good economic returns
• Saving energy, reducing consumption, no "three wastes" discharge
• Stable operation, reliable operation, easy maintenance, wide raw material adaptability
• Granulating, molding, screening integrated into one machine
• Finished product with good appearance, easy to operate
• Main components such as roller body use new type metal with anti-corrosive, abrasion resistance, shock resistance characteristics
• Bearing bracket selects excellent anti-corrosion casting parts for whole body
• Transmission part adopts two-input transfer mode for improved power ratio and lubrication performance
