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.

Particle Size

Fine LFP particles may remain suspended for a long time. Particle-size distribution and settling tests should be checked before selection.

Slurry Concentration and Viscosity

High solids loading or viscosity may reduce throughput. Stable feeding is important for consistent separation.

Process-Liquid Composition

The liquid may contain water, lithium salts, iron salts, phosphates, acids, alkalis, dispersants, or binders. The complete composition should be provided.

Product Purity

LFP production may have strict contamination limits. Wetted materials and wear-resistant components should be selected to reduce metal contamination.

Flocculant Compatibility

Flocculant may improve fine-particle capture, but it should not affect product reuse or downstream processing.

High LFP Recovery

High centrifugal force continuously recovers valuable lithium iron phosphate particles and reduces material loss.

Stable Slurry Thickening

Adjustable bowl speed, differential speed, pond depth, and feed rate provide stable operation.

Process-Water Recycling

Clarified liquid can be returned to washing or slurry preparation when it meets the required quality.

Purity and Wear Control

Suitable wetted materials and wear-resistant components support reliable battery-material processing.

Please provide:

• Particle size and solids concentration
• Slurry density, viscosity, pH, and temperature
• Liquid composition and purity requirement
• Required capacity and recovery target
• Downstream filter press or dryer
• Material and wear-protection requirements

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.
