NPK Granulation Lines
Our NPK Granulation Lines are designed to meet the demands of modern agriculture by producing high-quality, uniform NPK (Nitrogen, Phosphorus, Potassium) granules.
We provide comprehensive solutions from initial design to full-scale operation, ensuring your production line is efficient, reliable, and tailored to your specific requirements.
Step 1: Dosing of Raw Materials
- Weighing and Metering Systems
- Automated Feeder Systems
- Material Flow Controllers
Step 2: Pre-Mixing
- High-Efficiency Ribbon Mixers
- Continuous Inline Mixing
- Useful for large-scale operations
Step 3: Granulation
Granulation Technology:
- The slurry from the reactor is fed directly into a granulator, such as a rotary drum granulator, where it coats seed particles or nuclei.
- The rotation of the drum and the cascading motion of the material inside promote granule formation and ensure that the granules achieve the desired size and shape.
Step 4: Drying and Cooling
- The granules produced from the slurry are typically dried in a rotary dryer.
- After drying, the granules are cooled in a cooler, often a rotary or fluidized-bed cooler, to stabilize the product and prepare it for screening and storage.
Step 5: Screening and Milling
- Multi-stage screening systems that allow for the classification of granules into different size categories.
- crushing systems to break down oversized granules into smaller particles, which are then reintroduced into the granulation process.
