High‑Automation NPK Compound Fertilizer Production Line Flexible Formula Adjustment for Different NPK Ratios

Complete continuous compound fertilizer processing and granule formation system designed for producing granular compound fertilizer with adjustable nitrogen-phosphorus-potassium ratios.

This complete NPK compound fertilizer production line covers the full-process workflow from automatic batching to finished-product packaging. The system produces uniform fertilizer granules with high mechanical strength and excellent anti-caking performance, making them ideal for storage, transportation, and farm application.

• Flexible formula adjustment supporting various NPK proportion formulas for different crop demands
• Two optional granulation technologies: wet drum granulation or dry double-roller extrusion granulation
• High granulation rate, stable continuous running, low failure rate, and easy maintenance
• Modular configuration with customizable whole-line layout according to customer workshop and site conditions
• High automation level reducing manual operation with return material recycling system
• Finished round granules with high strength, resistant to breakage and anti-caking for long-term storage

• Raw material automatic batching
• Crushing
• Mixing homogenization
• Granulation
• Drying
• Cooling
• Rotary screening
• Finished-product packaging

Unqualified oversized & fine powder returns back for re-granulation to realize material recycling.

Application Scenarios: Compound fertilizer manufacturing plants, large-scale chemical fertilizer factories, agricultural fertilizer production projects.

Applicable Raw Materials: Urea, ammonium chloride, ammonium sulfate, monoammonium phosphate, diammonium phosphate, potassium chloride, potassium sulfate, bentonite and other NPK chemical filler raw materials.
