Automated NPK Fertilizer Production Line for Blending Granulating Coating

Optimize your NPK fertilizer production with our Automated Blending, Granulating & Coating System. This industrial-grade production line provides a complete and efficient solution for manufacturing high-quality NPK compound fertilizers. From precise raw material blending to uniform granulation and protective coating, our system ensures consistent product quality, reduced waste, and maximized output.

• Fully Automated System: Automated blending, granulating, and coating processes minimize manual labor and ensure consistent product quality. PLC control systems provide real-time monitoring and precise control over the entire production line.
• Precise Blending Technology: Automated batching systems and high-efficiency mixers ensure accurate proportioning of raw materials and uniform nutrient distribution in the final product. Options include double-shaft blenders, disc blenders, and horizontal blenders.
• Versatile Granulation Options: Choose from various granulation methods to suit your specific needs, including rotary drum granulation, disc granulation, and double roller extrusion granulation.
• Advanced Coating Technology: Integrated coating machines apply a protective layer to the fertilizer granules, preventing caking, controlling nutrient release, and enhancing the product's appearance. Coating materials can include polymers, sulfur, resins, or other specialized formulations.

The production line includes all necessary equipment for a streamlined process:

• Feeding and Batching Systems
• Crushing and Mixing Equipment
• Granulators
• Drying and Cooling Systems
• Screening Equipment
• Coating Machines
• Packaging Machines

• Durable Construction: Built with high-quality, corrosion-resistant materials such as stainless steel for long-lasting performance and reliability.
• Customizable Design: Plants are customized according to clients' specific needs and requirements, including raw materials and end-product specifications.

• NPK Compound Fertilizer Production: Manufacturing of granular NPK fertilizers with various nutrient ratios to meet the specific needs of different crops.
• Custom Fertilizer Blending: Creating tailored fertilizer mixes with nitrogen, phosphorus, potassium, and micronutrients for precision farming.
• Slow-Release Fertilizer Production: Producing fertilizers with controlled nutrient release for improved efficiency and reduced environmental impact.

1. Raw Material Preparation: Raw materials (nitrogen, phosphate, potassium sources, and other additives) are prepared, often involving crushing and grinding to achieve a suitable particle size.
2. Automated Blending: Raw materials are automatically batched and precisely mixed according to the desired NPK ratio and fertilizer formulation.
3. Granulation: The mixed materials are granulated using a suitable method (rotary drum, disc, extrusion, etc.) to form granules. Wet granulation often involves spraying a liquid binder.
4. Drying: The wet granules are dried to reduce moisture content and prevent caking.
5. Cooling: The dried granules are cooled to stabilize them and prepare them for screening and coating.
6. Screening: Granules are screened to separate them by size, ensuring a uniform product. Oversized and undersized particles are typically recycled back into the process.
7. Coating (Optional): Granules may be coated to improve handling characteristics, control nutrient release, or enhance their appearance. Coating materials are applied using a rotary drum or fluidized bed coating system.
8. Packaging: The finished fertilizer granules are automatically weighed and packaged into bags for storage and distribution.
