Full Automatic NPK Compound Fertilizer Production Line with Wide Raw Material Compatibility and Modular Configuration

This complete NPK compound fertilizer production line is engineered for manufacturing granular NPK compound fertilizer. The system automates the entire process from raw material batching to final packaging, producing uniform fertilizer granules with high hardness and excellent physical properties. Ideal for medium to large-scale fertilizer manufacturing facilities requiring flexible formula adjustments.

• Fully automated continuous production with flexible formula adjustment for various NPK ratios
• Stable operation with high granulation rate, low failure rate, and easy maintenance
• Wide compatibility with nitrogen, phosphorus, and potassium raw materials
• Modular configuration with customizable production capacity
• Low dust emission and compact layout for efficient workshop space utilization
• Produces round, durable granules that resist breakage and facilitate storage

Automated proportioning of nitrogen, phosphorus, and potassium raw materials → Crushing into fine powder → Complete mixing → Granulation into round particles → Drying to reduce moisture → Cooling → Screening to separate qualified granules → Final packaging of finished granules.

• Automatic Batching System: Precisely weighs N, P, K raw materials
• Material Crusher: Processes bulk raw materials into fine powder
• Mixer: Ensures uniform blending of all powder materials
• Granulator: Transforms powder into round fertilizer granules
• Dryer & Cooler: Reduces moisture content and cools hot granules
• Rotary Screener: Separates qualified granules from oversized particles
• Automatic Packaging Machine: Packages finished NPK fertilizer

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

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