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.

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. Raw materials can be powder or bulk, including:

• Productive Technology: High-temperature drying process disinfects, decomposes, and dries materials, reducing moisture from 65% to below 13%
• Final Products: Contains essential crop nutrients with nitrogen content 2.6%, phosphorus 3.5%, potassium 2.5%, crude protein 16-25%, organic matter 45%
• High Efficiency: High mechanization degree, large production capacity, continuous operation capability
• Reliable Operation: Good and simple structure, easy material flow through barrel, simple operation
• Cost Effective: Minimal malfunctions, low maintenance costs, reduced power consumption
• Versatile Application: Wide usage range, uniform product drying quality
• Additional Benefits: Simultaneous sterilization and deodorization during drying process

Energy saving and consumption reducing, no waste removal, stable operation, reliable running, convenient maintenance. The machine features wide raw material adaptability and is suitable for granulation of compound fertilizer, medicine, chemical industry, feed, etc., with high granulation rate. Capable of producing various compound fertilizers with different concentrations and types including organic fertilizer, inorganic fertilizer, biological fertilizer, and magnetic fertilizer.
