Description

  1. Mixing Raw Materials: Blend nitrogen, phosphorus, potassium, and additives while adding water for optimal granule strength.
  2. Conveying and Cleaning: Use a belt conveyor to transport mixed materials, removing iron contaminants for purity.
  3. Extrusion Granulation: Process materials through an extrusion granulator to form uniform fertilizer balls.
  4. Initial Screening: Screen semi-finished granules and recycle fine particles back to the mixer for reprocessing.
  5. Moisture Drying: Dry the granules to enhance strength and ensure long-term storage stability.
  6. Cooling Process: Cool dried particles to prevent clumping and maintain quality.
  7. Secondary Screening: Classify cooled particles, returning fine granules to the production line.
  8. Coating for Quality: Apply coatings to improve appearance and prevent clumping with anti-caking agents.
  9. Automated Packaging: Weigh and package the final product using advanced automation for efficiency.
  10. Dust Control Systems: Implement a pulse bag filter to capture dust, ensuring an eco-friendly production environment.

 

Advantages of Extrusion Granulation

  • Energy Efficiency: No heating required, ideal for heat-sensitive materials.
  • Environmentally Friendly: Zero wastewater or harmful emissions.
  • High Production Efficiency: Short process time with easy automation.
  • Versatile Raw Material Usage: Adaptable to various material properties.
  • Flexible Production Plans: Easily adjust for specialized fertilizers.
  • Uniform Granule Quality: Consistent particle size without clumping.

This optimized process enhances fertilizer production while being environmentally responsible and energy-efficient.
