The Decanter Centrifuge for Rare Earth Slurry Recovery is designed for continuous solid-liquid separation, valuable rare earth solids recovery, slurry thickening, and process-liquid clarification.

It is suitable for rare earth leaching residue, precipitation slurry, washing slurry, extraction wastewater, polishing-material slurry, and mineral beneficiation wastewater.

The centrifuge separates rare earth compounds, mineral fines, hydroxide precipitates, leaching residues, and suspended impurities from the liquid phase.

Rare Earth Material Type

Confirm whether the slurry contains rare earth oxides, hydroxides, carbonates, phosphates, polishing powders, or leaching residues.

Particle Size

Fine rare earth particles may settle slowly. Particle-size distribution and settling tests should be checked before selection.

Slurry Concentration and Viscosity

High solids concentration or viscosity may reduce processing capacity. Stable feeding helps maintain consistent separation.

Liquid Composition

The liquid phase may contain acids, alkalis, chlorides, sulfates, ammonium salts, extractants, or residual metal ions.

Corrosion and Wear

Corrosion-resistant materials and wear protection should be selected according to the slurry chemistry and mineral impurity content.

High Rare Earth Recovery

High centrifugal force continuously recovers valuable rare earth solids and reduces material loss.

Stable Slurry Thickening

Adjustable operating parameters maintain stable separation under changing feed conditions.

Lower Downstream Load

Pre-thickening reduces the liquid volume entering filter presses, dryers, or calcination systems.

Process-Liquid Recycling

Clarified liquid can be returned to washing, extraction, or further metal recovery.

Corrosion and Wear Protection

Customized materials and internal protection support acidic, alkaline, and abrasive slurry conditions.

Please provide:

• Rare earth material type
• Process stage
• Particle-size distribution
• Feed solids concentration
• Slurry density and viscosity
• Liquid composition
• Feed temperature and pH
• Required processing capacity
• Required solids recovery rate
• Target solids concentration
• Clarified-liquid quality requirement
• Corrosive and abrasive components
• Flocculant currently used
• Downstream filtration or drying process
• Required material of construction

Peony welcomes cooperation with rare earth processing plants, mineral beneficiation companies, polishing-material producers, metal recovery companies, wastewater treatment contractors, distributors, and industrial separation partners.

We support partners with slurry testing, centrifuge selection, corrosion-resistant materials, wear protection, process-liquid recycling, installation guidance, commissioning, spare parts, and after-sales service.
