The Decanter Centrifuge for Battery Material Slurry Recovery is designed for continuous solid-liquid separation, valuable powder recovery, slurry thickening, and process-liquid clarification.
It is suitable for battery material washing slurry, precipitation slurry, grinding and classification slurry, precursor production wastewater, black mass treatment residue, and other compatible battery-material suspensions.
The centrifuge separates active-material particles, precursor solids, graphite fines, carbon particles, metal-containing residues, and suspended impurities from the liquid phase.
| Process Requirement | Decanter Centrifuge Solution |
|---|---|
| Valuable powder recovery | Continuous high-force separation |
| Fine particle capture | Adjustable bowl speed and optional dosing |
| Variable slurry concentration | Adjustable differential speed and feed rate |
| Product purity control | Suitable wetted materials and wear protection |
| Lower filtration load | Pre-thickening before filter press or dryer |
| Process-liquid recycling | Clarified liquid for reuse or treatment |
| Corrosive process liquid | Customized materials and sealing system |
| Automatic operation | PLC and VFD-controlled continuous running |
Peony provides continuous separation solutions for battery material recovery, slurry thickening, process-liquid clarification, and wastewater-volume reduction.
Battery Material Washing / Precipitation / Grinding / Leaching
→ Agitated Slurry Tank
→ Optional Conditioning or Flocculant Dosing
→ Decanter Centrifuge
→ Thickened Battery Material Solids
→ Filter Press / Dryer / Reprocessing / Metal Recovery
Clarified Liquid
→ Process-Liquid Tank
→ Recycle / Polishing Filtration / Further Treatment
The 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 battery material 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 battery material solids are discharged continuously.
The recovered solids can be sent to a filter press, dryer, reprocessing system, metal-recovery process, or storage tank.

Confirm whether the slurry contains LFP, NCM precursor, graphite, conductive carbon, black mass residue, or other battery materials.
Different materials have different densities, particle sizes, chemical conditions, and purity requirements.
Fine or well-dispersed particles may settle slowly.
Particle-size distribution, particle density, and settling tests should be checked before model selection.
High solids loading or viscosity may reduce throughput.
Stable feeding is important for consistent solids recovery and liquid clarification.
The liquid phase may contain water, acids, alkalis, lithium salts, metal salts, binders, dispersants, or compatible solvents.
The complete composition, pH, temperature, and corrosive components should be provided.
Battery materials may have strict contamination limits.
Wetted materials, wear-resistant components, internal surface finish, and cleaning design should match the required purity standard.
High centrifugal force continuously recovers valuable battery material particles and reduces product loss.
Adjustable operating parameters maintain stable separation under changing solids concentration and viscosity.
Pre-thickening reduces the liquid volume entering filter presses, dryers, or metal-recovery equipment.
Clarified liquid can be reused in washing or slurry preparation when it meets the process requirement.
Customized materials, wear protection, and sealing configurations support high-purity and corrosive applications.
Please provide:
Yes. Separation depends on particle size, density, slurry stability, and liquid viscosity. Very fine particles may require slurry conditioning or polishing filtration.
Yes. The centrifuge can be selected for LFP, NCM precursor, and other compatible battery material slurries after confirming the process conditions.
Yes. Clarified liquid can often be returned to washing or slurry preparation after confirming its quality.
Potentially. The solvent type, flash point, sealing requirements, and explosion-protection standard must be evaluated separately.
The decanter is mainly used for continuous recovery, thickening, and primary dewatering. A filter press or dryer may still be required for lower final moisture.
Peony welcomes cooperation with battery material manufacturers, cathode and anode material plants, lithium recycling companies, black mass processors, engineering contractors, wastewater treatment companies, distributors, and industrial separation partners.
We support partners with slurry testing, centrifuge selection, corrosion-resistant materials, contamination-control design, wear protection, process-liquid recycling, installation guidance, commissioning, spare parts, and after-sales service.
Send us your battery material slurry information, including material type, 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 battery material slurry recovery process.
