5-20t/h Capacity NPK Compound Fertilizer Production Line with High Granulation Rate and Modular Configuration

This complete NPK compound fertilizer production line adopts wet granulation technology to produce granular NPK compound fertilizer. The entire workflow includes automatic batching, crushing, mixing, granulation, drying, cooling, screening, and finished-goods packaging.

The system can produce multiple different N-P-K ratio compound fertilizer products. Finished fertilizer granules feature uniform particle size, high hardness, anti-caking performance, and are convenient for storage, transportation, and agricultural application. It is widely used for medium- and large-scale chemical fertilizer factories and fertilizer manufacturing projects.

• Fully-automatic continuous running with flexible adjustment for various NPK fertilizer formulas
• High granulation rate, stable particle hardness, and low breakage rate of finished fertilizer granules
• Modular configuration with customizable capacity and layout according to customer workshop site
• Good compatibility for urea, ammonium salt, phosphate, potassium salt, and other chemical powder raw materials
• Complete material return system with under-size and over-size granules returning for re-processing, ensuring high raw-material utilization
• Low failure rate, easy maintenance, and stable long-time mass production capability

NPK raw materials automatic batching → crushing into fine powder → sufficient mixing → wet granulation → drying to reduce moisture → cooling hot granules → rotary screening → qualified granules finished packaging.

• Automatic Batching System: Accurately weighs nitrogen, phosphorus, and potassium raw materials according to formula
• Material Crusher: Crushes lump chemical raw materials into fine powder
• Horizontal Mixer: Ensures even mixing of multi-component powder raw materials
• Rotary Drum Granulator: Core wet-granulation equipment to form spherical fertilizer granules
• Rotary Dryer & Rotary Cooler: Controls granule moisture and cools down high-temperature pellets
• Rotary Trommel Screen: Separates qualified granules and unqualified return materials
• Optional Coating Machine: Anti-caking coating treatment for fertilizer surface
• Automatic Quantitative Packaging Machine: Weighs and packs finished NPK fertilizer

Application Scenarios: Compound fertilizer manufacturing plant, large-scale chemical fertilizer factory, agricultural fertilizer production project, turn-key fertilizer plant construction.

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