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.
Fine cerium oxide particles may remain suspended and settle slowly.
Higher centrifugal force, stable feeding, and optional coagulation or flocculation can improve recovery.
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.
Dispersants and surfactants can keep ceria particles stable in the liquid phase.
pH adjustment or chemical conditioning may be needed before centrifugation.
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.
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.

→ Decanter Centrifuge
→ Thickened Ceria Solids
→ Filter Press / Dryer / Recovery

→ Water Tank
→ Filtration / Membrane Treatment
→ Reuse or Discharge
Conditioned cerium oxide slurry enters the rotating bowl through a controlled feed pipe.
An agitated tank maintains stable solids concentration and prevents ceria particles from settling in the feed tank.
High-speed bowl rotation separates cerium oxide particles, glass fines, and suspended solids from the liquid phase.
The denser particles move outward and form a solids layer against the bowl wall.
The internal screw conveyor rotates at a controlled differential speed.
It transports the settled ceria solids toward the conical end for further thickening and discharge.
The separated liquid leaves through the liquid outlet.
It can be sent to polishing filtration, membrane treatment, process-water recovery, or further wastewater treatment.
Concentrated cerium oxide solids are discharged continuously.
The recovered material can be sent to filtration, drying, purification, cerium recovery, reuse evaluation, or controlled disposal.

The centrifuge recovers suspended cerium oxide particles from polishing slurry and reduces valuable material loss.
Stable continuous operation reduces the slurry volume sent to filter presses, dryers, or recovery systems.
Separated liquid can be transferred to polishing filtration or further treatment for possible reuse.
Carbide and ceramic protection reduce wear caused by ceria abrasives and glass fines.
Wetted materials and wear components can be selected according to ceria purity and downstream reuse requirements.
Please provide:
It depends on particle size and slurry stability. Ultrafine or highly dispersed ceria may require pH adjustment, coagulation, or flocculation before centrifugation.
Not usually without testing. Particle size, purity, agglomeration, polishing performance, and contamination must first be verified.
Yes. It can separate cerium oxide, glass fines, silica particles, and suspended polishing residues from the liquid phase.
It may require polishing filtration or membrane treatment before reuse. The final suspended-solids and contamination limits should be confirmed.
It is recommended when abrasion and metallic contamination are both important concerns. The final material should match the required ceria purity.
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.
Send us your cerium oxide slurry information, including particle size, solids concentration, slurry chemistry, required capacity, recovery target, purity requirement, and downstream treatment arrangement. Our engineering team will recommend a suitable decanter centrifuge solution for your cerium oxide slurry recovery process.
