Rotary Drum Ammoniation Granulator NPK Compound Fertilizer Production Line with Chemical Reaction System
Rotary Drum Ammoniation NPK Compound Fertilizer Production Line
This Rotary Drum Ammoniation Granulator Production Line utilizes chemical reaction heat generated by acid-base neutralization to drive the granulation process, significantly reducing external energy consumption while producing high-concentration NPK compound fertilizers with superior granule hardness.
Ammoniation Technology Advantages
- Pipe Reactor System: Phosphoric acid and ammonia react inside a tubular reactor before being sprayed into the rotary drum granulator, utilizing reaction heat (120-150°C) for moisture evaporation and granule formation
- Steam Injection Granulation: Superheated steam injected into the granulation drum raises material temperature to 55-75°C, dissolving soluble salts and promoting liquid-phase granulation for high-strength spherical particles
- Acid-Base Neutralization: Exothermic reaction between ammonia and phosphoric/sulfuric acid provides free thermal energy that replaces 40-60% of external fuel consumption in the drying stage
- High Granule Hardness: Chemical bonding during ammoniation produces granules with crushing strength exceeding 30N, far superior to physical granulation methods
- Continuous Production: Fully continuous process from raw material feeding to finished product, suitable for 50,000-300,000 tons annual capacity plants
