Decanter Centrifuge for Zirconia Slurry Dewatering

The Decanter Centrifuge for Zirconia Slurry Dewatering is designed for continuous solid-liquid separation, zirconia powder recovery, slurry thickening, and process-liquid clarification.

It is suitable for zirconia powder washing, wet grinding, classification overflow, precipitation slurry, ceramic processing wastewater, and fine zirconia recovery. The centrifuge separates zirconia particles, ceramic fines, agglomerates, and suspended impurities from the liquid phase.

Particle Size

Submicron or well-dispersed zirconia particles may settle slowly. 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.

Dispersants and Additives

Dispersants, binders, surfactants, and pH regulators can affect particle settling and clarified-liquid quality.

Abrasive Wear

Zirconia particles can cause wear in the feed zone, screw conveyor, conical section, and solids-discharge ports. Wear protection is recommended for continuous operation.

Product Purity

For advanced ceramic applications, wetted materials and wear-resistant components should be selected to reduce metal contamination.

Flocculant Compatibility

Flocculant may improve fine-particle recovery, but testing is recommended to avoid contamination or downstream process problems.

High Zirconia Recovery

High centrifugal force continuously separates dense zirconia particles from washing water, grinding slurry, and classification overflow, reducing valuable powder loss.

Stable Fine-Slurry Thickening

Adjustable bowl speed, differential speed, pond depth, and feed rate maintain stable thickening under changing solids concentration and viscosity.

Reduced Metal Contamination

Suitable wetted materials, protected wear areas, and optional ceramic wear components help maintain zirconia purity for advanced ceramic processing.

Wear-Resistant Configuration

The feed zone, scroll conveyor, conical section, and solids outlets can be protected against abrasion caused by zirconia particles.

Process-Liquid Recycling

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