The Decanter Centrifuge for Cerium Oxide Slurry Recovery is designed for continuous ceria-particle recovery, slurry thickening, polishing-water clarification, and downstream filtration preparation.

It is suitable for glass polishing, optical lens processing, precision ceramics, semiconductor polishing, crystal processing, and cerium oxide production.

• Cerium-containing sludge reduction
• Process-water recycling

Ultrafine Ceria Particles

Fine cerium oxide particles may remain suspended and settle slowly.

Higher centrifugal force, stable feeding, and optional coagulation or flocculation can improve recovery.

Glass and Polishing Residues

Spent polishing slurry may contain glass fines, silica, pad debris, and other impurities.

These materials can affect recovered ceria purity and determine whether the solids are suitable for reuse or only for resource recovery.

Slurry Dispersion

Dispersants and surfactants can keep ceria particles stable in the liquid phase.

pH adjustment or chemical conditioning may be needed before centrifugation.

Abrasive Wear

Cerium oxide and glass fines can wear the feed zone, scroll conveyor, conical section, and solids outlets.

Carbide or ceramic protection can be installed in high-wear areas.

Product Contamination

For high-value ceria recovery, internal materials and wear components should be selected according to the allowable metal and mineral contamination level.

Peony provides continuous solutions for ceria recovery, slurry thickening, and polishing-water clarification.

Ceria Particle Recovery

The centrifuge recovers suspended cerium oxide particles from polishing slurry and reduces valuable material loss.

Continuous Slurry Thickening

Stable continuous operation reduces the slurry volume sent to filter presses, dryers, or recovery systems.

Polishing-Water Clarification

Separated liquid can be transferred to polishing filtration or further treatment for possible reuse.

Wear-Resistant Configuration

Carbide and ceramic protection reduce wear caused by ceria abrasives and glass fines.

Low-Contamination Design

Wetted materials and wear components can be selected according to ceria purity and downstream reuse requirements.

Please provide:

• Slurry source and process stage
• Ceria particle size and solids concentration
• Slurry density, viscosity, pH, and flow rate
• Dispersant, surfactant, and impurity content
• Required recovery rate and liquid clarity
• Downstream filtration, drying, or reuse process

Peony welcomes distributor and agent cooperation with optical glass plants, lens manufacturers, display-glass processors, precision polishing companies, cerium oxide producers, semiconductor wastewater contractors, and material-recovery partners.

We support partners with ceria slurry testing, centrifuge selection, chemical-conditioning design, low-contamination configuration, wear protection, polishing-water recovery, filter press integration, installation guidance, commissioning, spare parts, and after-sales service.
