Dry Type NPK Fertilizer Production Line with Oval Shape Granules and 380v Power

Our NPK Fertilizer Manufacturing Plant offers comprehensive solutions for compound fertilizer production with advanced technology and reliable performance.

The compound fertilizer production line process 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 essential plant nutrients—Nitrogen, Phosphorus, and Potassium—along with microelements such as B, Mn, Cu, Zn, and Mo. Raw materials can be in powder or bulk form:

The NPK compound fertilizer production line typically includes 7 processes: batching, grinding, mixing, granulating, screening, coating and packaging. Batching, mixing, granulating and screening processes are essential, while others are optional based on production capacity requirements.

The system employs extrusion sliding model design where raw materials pass through double rollers, enter the scattering room, and emerge as granules. A customized sieving mechanism at the machine bottom screens qualified granules, while remaining materials return to the mixer for re-granulation.

• Advanced Technology: High-temperature drying, disinfection, decomposition and drying processes transform fresh materials with 65% moisture into pure organic fertilizer with below 13% moisture content
• Quality Final Products: Contains essential crop nutrients with nitrogen content 2.6%, phosphorus 3.5%, potassium 2.5%, crude protein 16-25%, and organic matter 45% - ideal for pollution-free green food cultivation and animal feed
• High Mechanization: Drum drying offers high automation, large production capacity, and continuous operation capability
• Robust Construction: Simple yet effective barrel design with minimal material resistance for easy operation
• Reliable Performance: Minimal malfunctions, low maintenance costs, and energy-efficient operation
• Versatile Application: Wide product applicability with consistent drying uniformity
• Additional Benefits: Simultaneous sterilization and deodorization during drying process

Energy-saving operation with no waste removal, stable and reliable performance, and convenient maintenance. The system accommodates wide raw material adaptability, suitable for granulation of compound fertilizers, pharmaceuticals, chemicals, feed, and more. High granulation rate enables production of various compound fertilizers including organic, inorganic, biological, magnetic fertilizers with different concentrations and types.
