Product Description
NPK Fertilizer Double Roller Granulation Production Line – One-Step Forming, Energy Saving
The Double Roller Extrusion Granulation Line is an advanced dry granulation system designed for the production of NPK compound fertilizer, organic-inorganic blended fertilizer, and BB fertilizer. Unlike traditional drum granulation lines that require drying and cooling, this line adopts extrusion technology to form granules at room temperature, eliminating the need for dryers, coolers, and fuel consumption.
With capacities ranging from 1 to 30 tons per hour (10,000-200,000 tons per year), this line offers a compact, energy-saving, and cost-effective solution for fertilizer manufacturers worldwide.
Why Choose Dry Extrusion Granulation?
| Comparison | Wet Granulation (Drum) | Dry Extrusion (Double Roller) |
|---|---|---|
| Drying required | Yes - high energy cost | No - room temperature |
| Cooling required | Yes | No |
| Fuel consumption | High | Zero |
| Equipment footprint | Large | Compact |
| Investment cost | High | Low |
| Waste water/gas | Yes | No |
| Granulation rate | 60-70% | 85-95% |
Production Process Steps
- Batching System - Multiple bins with screw or belt feeders controlled by PLC for precise weighing.
- Mixing System - Double-shaft horizontal mixer ensures homogeneous blending of N, P, K, and additives.
- Granulation System - Double roller extruder presses material into high-density strips under 15-25 tons pressure.
- Crushing System - Chain crusher breaks strips into small particles.
- Screening System - Rotary drum screener separates qualified granules (1-6 mm) from fines.
- Polishing System (Optional) - Spheronizer rounds granules for smooth surface and uniform shape.
- Coating System (Optional) - Rotary drum coater applies anti-caking agent or functional coating.
- Packaging System - Automatic scale bagger with sewing machine or heat sealer.
Raw Material Compatibility
This line works with a wide range of fertilizer raw materials:
- Nitrogen sources: Urea (prilled or granular), ammonium sulfate, ammonium chloride, ammonium nitrate
- Phosphate sources: MAP, DAP, SSP, triple superphosphate (TSP), calcium-magnesia phosphate
- Potassium sources: MOP (potassium chloride), SOP (potassium sulfate)
- Additives: Boron (B), manganese (Mn), zinc (Zn), copper (Cu), iron (Fe), anti-caking agents, binders (optional, usually not required)
Key Advantages
- Low Investment, Quick Payback - No dryer, cooler, or hot air furnace required. 30-40% lower equipment cost compared to wet granulation lines.
- Energy Saving - Zero fuel consumption. Only electricity needed - 40-50% less energy than drum lines.
- Environmentally Friendly - No waste water discharge. No exhaust gas or dust emission (enclosed system).
- Easy Operation - Simple process flow with fewer equipment. PLC automatic control reduces labor (2-3 operators per shift).
- High Granule Quality - High density granules with smooth surface. Low caking tendency during storage. Uniform size for even spreading.
- Flexible Production - Switch between different NPK formulas in 30 minutes. Produce compound fertilizer, organic compound fertilizer, or BB fertilizer base granules.
Typical Applications
| Application | Description |
|---|---|
| NPK compound fertilizer | 20-20-20, 15-15-15, 16-16-16, 25-10-10, etc. |
| High-concentration fertilizer | Total NPK up to 48% |
| Organic-inorganic blend | Mix with fermented organic matter (30-50%) |
| Urea-based fertilizer | High nitrogen formulas for rice, corn, wheat |
| Sulfate-based fertilizer | For chlorine-sensitive crops (tobacco, potato, fruit) |
Features of NPK Fertilizer Production Line
- Simple machine structure
- Easy operation and maintenance
- One-time forming, no drying process, normal temperature granulation
- Double-shaft power output - each shaft drives its roller via coupling for synchronous counter-rotating operation, resulting in better granule formation and higher strength
- Simple ball socket alignment adjustment design, convenient for customer self-adjustment. Roller adjustment drawing and operation steps are provided
- All machines are tested and trial-produced by professional workers before leaving the factory
