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