- LCD glass processing wastewater
- Crystal and quartz polishing slurry
- Precision ceramic polishing wastewater
- Spent ceria slurry thickening
- Fine ceria particle recovery
- Filter press feed preparation
- Polishing-water clarification
- 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.

How the Decanter Centrifuge Works
1. Cerium Oxide Slurry Feeding
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.
2. Centrifugal Sedimentation
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.
3. Continuous Solids Conveying
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.
4. Clarified Liquid 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.
5. Thickened Ceria Solids Discharge
Concentrated cerium oxide solids are discharged continuously.
The recovered material can be sent to filtration, drying, purification, cerium recovery, reuse evaluation, or controlled disposal.

Main Advantages
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
Can the centrifuge recover ultrafine cerium oxide particles?
It depends on particle size and slurry stability. Ultrafine or highly dispersed ceria may require pH adjustment, coagulation, or flocculation before centrifugation.
Can recovered ceria be reused directly for polishing?
Not usually without testing. Particle size, purity, agglomeration, polishing performance, and contamination must first be verified.
Can it treat glass polishing slurry?
Yes. It can separate cerium oxide, glass fines, silica particles, and suspended polishing residues from the liquid phase.
Can clarified water return directly to polishing equipment?
It may require polishing filtration or membrane treatment before reuse. The final suspended-solids and contamination limits should be confirmed.
Is ceramic wear protection recommended?
It is recommended when abrasion and metallic contamination are both important concerns. The final material should match the required ceria purity.
