The Decanter Centrifuge for Lithium Iron Phosphate Slurry Recovery is designed for continuous solid-liquid separation, LFP powder recovery, slurry thickening, and process-liquid clarification.
It is suitable for lithium iron phosphate production, iron phosphate precursor processing, washing slurry, grinding and classification slurry, precipitation slurry, and battery-material wastewater treatment.
The centrifuge separates LFP particles, iron phosphate solids, carbon-containing fines, metal-containing residues, and suspended impurities from the liquid phase.
| Process Requirement | Decanter Centrifuge Solution |
|---|---|
| Valuable LFP recovery | Continuous high-force separation |
| Fine particle capture | Adjustable bowl speed and optional dosing |
| Variable slurry concentration | Adjustable differential speed and feed rate |
| Stable thickening | Controlled pond depth and solids conveying |
| Product purity control | Suitable wetted and wear-resistant materials |
| Lower filtration load | Pre-thickening before filter press or dryer |
| Process-water recycling | Clarified liquid for reuse or treatment |
| Automatic operation | PLC and VFD-controlled continuous running |
Peony provides continuous separation solutions for LFP powder recovery, slurry thickening, process-water clarification, and downstream filtration preparation.
LFP Washing / Grinding / Classification / Precipitation
→ Agitated Slurry Tank
→ Optional Conditioning or Flocculant Dosing
→ Decanter Centrifuge
→ Thickened LFP Solids
→ Filter Press / Dryer / Reprocessing / Storage
Clarified Liquid
→ Process-Water Tank
→ Recycle / Polishing Filtration / Further Treatment
Lithium iron phosphate slurry enters the rotating bowl through a controlled feed pipe.
An agitated tank helps prevent particle settling and maintains a stable feed concentration.
High-speed rotation separates LFP particles from the liquid phase.
The denser solids move outward and form a layer against the bowl wall, while clarified liquid remains closer to the center.
The internal screw conveyor rotates at a controlled differential speed.
It continuously transports settled solids toward the conical end for further dewatering.
The separated liquid leaves through the liquid outlet.
It can be returned to washing or slurry preparation, sent to polishing filtration, or transferred to further treatment.
Concentrated LFP solids are discharged continuously.
The recovered solids can be sent to a filter press, dryer, reprocessing system, or storage tank.

Fine LFP particles may remain suspended for a long time. Particle-size distribution and settling tests should be checked before selection.
High solids loading or viscosity may reduce throughput. Stable feeding is important for consistent separation.
The liquid may contain water, lithium salts, iron salts, phosphates, acids, alkalis, dispersants, or binders. The complete composition should be provided.
LFP production may have strict contamination limits. Wetted materials and wear-resistant components should be selected to reduce metal contamination.
Flocculant may improve fine-particle capture, but it should not affect product reuse or downstream processing.
High centrifugal force continuously recovers valuable lithium iron phosphate particles and reduces material loss.
Adjustable bowl speed, differential speed, pond depth, and feed rate provide stable operation.
Clarified liquid can be returned to washing or slurry preparation when it meets the required quality.
Suitable wetted materials and wear-resistant components support reliable battery-material processing.
Please provide:
Yes. Separation depends on particle size, density, slurry stability, and liquid viscosity. Very fine particles may require conditioning or polishing filtration.
Yes. The centrifuge can be used for iron phosphate slurry thickening and washing-liquid clarification.
Yes. It can often be reused in washing or slurry preparation after confirming the liquid quality.
Not always. It depends on particle size, slurry concentration, settling behavior, and clarified-liquid requirements.
The decanter is mainly used for continuous recovery and pre-thickening. A filter press or dryer may still be required for lower final moisture.
Peony welcomes cooperation with LFP manufacturers, iron phosphate producers, battery material plants, lithium recycling companies, engineering contractors, wastewater treatment companies, distributors, and industrial separation partners.
We support partners with slurry testing, centrifuge selection, wear-resistant configuration, contamination-control design, process-water recycling, installation guidance, commissioning, spare parts, and after-sales service.
Send us your LFP slurry information, including particle size, solids concentration, liquid composition, required capacity, recovery target, purity requirement, and downstream arrangement. Our engineering team will recommend a suitable decanter centrifuge solution for your lithium iron phosphate slurry recovery process.
