FMP Fertilizer Production Line: Transforming Low-Grade Phosphate Rock into Eco-Friendly Fertilizer
Fused Magnesium Phosphate (FMP) is a citrate-soluble, slow-release phosphate fertilizer produced through high-temperature fusion and rapid quenching. Its unique properties make it ideal for acidic soils:
| Property | Traditional P-Fertilizers | FMP Fertilizer |
|---|---|---|
| P Solubility | Water-soluble (prone to fixation) | Citrate-soluble (releases in weak acids) |
| Raw Material | Requires high-grade ore (P₂O₅≥28%) | Accepts low-grade ore (P₂O₅≥12%) |
| Soil Compatibility | Neutral/alkaline soils | Optimized for acidic soils (pH<6.5) |
| Added Nutrients | Phosphorus only | P + Mg + Ca + Si (soil conditioner) |
| Environmental Impact | Generates phosphogypsum waste | Zero solid waste (only HF gas treatment) |
FMP fertilizer production line can convert low-value phosphate rock into long-lasting P-fertilizer while improving acidic soil structure.
A complete FMP fertilizer production line comprises 4 critical sections:
Process: Crushing → Drying → Grinding → Blending
Key Equipment:
Jaw Crusher: Primary size reduction (300–500 mm → 50–80 mm).
Rotary Dryer: Reduces moisture to <5% (fuel: natural gas/biomass).
Ball Mill: Pulverizes ore to 80–100 mesh (0.15–0.18 mm).
Automatic Batching System: Precision blending of phosphate rock (e.g., fluorapatite) and magnesium sources (olivine/serpentine) at 3:1–4:1 ratio.
Process: Melting (1,350–1,500°C) → Chemical reaction → Molten material handling
Key Equipment:
Submerged Arc Furnace (or Rotary Kiln):
Power: 8–12 MW for 50K t/yr capacity
Lining: Magnesia-carbon refractory bricks
HF Exhaust System:
High-temperature ducting → Quench tower → Scrubber (converts HF to Na₂SiF₆ byproduct).
Process: Water quenching → Drying → Crushing → Screening
Key Equipment:
Granulator: Molten stream + high-pressure water → Porous glassy granules (1–5 mm).
Rotary Cooler: Cools granules to <80°C.
Chain Crusher: Reduces oversized particles to powder.
Vibrating Screen: Separates product into 2–4 mm granules (yield: 85–90%).
Process: Neutralization (optional) → Packaging → Storage
Key Equipment:
Ammoniation Drum: Sprays NH₃ gas to adjust pH (optional).
Automatic Bagging Scale: 25–50 kg PP/PE woven bags with moisture barrier.
| Aspect | Benefit |
|---|---|
| Flexibility | Processes low-grade ores rejected by SSP/TSP plants |
| Energy Recovery | Waste heat powers pre-drying (cuts fuel use 15–20%) |
| Eco-Design | Zero solid waste; HF converted to marketable Na₂SiF₆ |
| Automation | PLC-controlled batching/fusion (≤3 operators/shift) |
Target Markets: Acidic lateritic soils (Latin America, West Africa, Southeast Asia).
Innovation Frontiers:
Co-granulation: Blending FMP with biochar/K-humate for premium products.
Zero-Emission HF Capture: Electrostatic precipitation + Na₂CO3 absorption (99.5% efficiency).
AI Optimization: Machine learning for real-time furnace temperature/ratio control.
