The Decanter Centrifuge for Fluorite Slurry Dewatering is designed for continuous solid-liquid separation, fluorite recovery, slurry thickening, and process-water clarification.
It is suitable for fluorite beneficiation, flotation concentrate treatment, tailings slurry thickening, washing-water clarification, and mineral-processing wastewater treatment.
The centrifuge separates fluorite particles, quartz, silica, clay, carbonate minerals, and other suspended solids from the liquid phase.

How the Decanter Centrifuge Works
1. Fluorite Slurry Feeding
Fluorite slurry enters the rotating bowl through a controlled feed pipe.
An agitated tank helps prevent mineral settling and maintains a stable feed concentration.
2. Centrifugal Sedimentation
High-speed rotation separates fluorite and other mineral particles from the liquid phase.
The denser solids move outward and form a layer against the bowl wall, while clarified liquid remains closer to the center.
3. Continuous Solids Conveying
The screw conveyor rotates at a controlled differential speed.
It continuously transports settled solids toward the conical end for further dewatering.
4. Clarified Liquid Discharge
The separated liquid leaves through the liquid outlet.
It can be returned to grinding, washing, flotation, or transferred to further wastewater treatment.
5. Thickened Fluorite Solids Discharge
Concentrated solids are discharged continuously.
The recovered fluorite slurry can be sent to a filter press, dryer, storage tank, regrinding system, or further beneficiation.

Fluorite Particle Size
Fine fluorite particles may settle slowly. Particle-size distribution and settling tests should be checked before selection.
Slurry Concentration
Feed concentration affects throughput, bowl torque, solids discharge, and clarified-liquid quality.
Mineral Impurities
Quartz, silica, sand, clay, and carbonate minerals can affect separation efficiency and equipment wear.
Flotation Reagents
Collectors, depressants, frothers, dispersants, and pH regulators may influence slurry stability and particle settling.
Process-Liquid Chemistry
The pH, temperature, dissolved salts, fluoride content, and other chemical components should be provided for material selection.
Improved Fluorite Recovery
Continuous centrifugal separation recovers fine fluorite solids and reduces valuable mineral loss.
Stable Tailings Thickening
Adjustable operating parameters maintain stable solids concentration under changing feed conditions.
Reduced Filtration Load
Pre-thickening reduces the liquid volume entering filter presses or dryers.
Process-Water Recycling
Clarified liquid can be reused in washing, grinding, flotation, or slurry preparation.
Wear-Resistant Design
Carbide, ceramic, or hard-faced components can protect high-wear areas from quartz and silica particles.
Please provide:
- Fluorite process stage
- Particle-size distribution
- Feed solids concentration
- Slurry density and viscosity
- Feed temperature and pH
- Required processing capacity
- Required fluorite recovery rate
- Target solids concentration
- Clarified-liquid quality requirement
- Quartz, silica, clay, and sand content
- Flotation reagents currently used
- Downstream filtration or drying equipment
- Required material of construction
- Wear-protection requirement
Can the centrifuge process both fluorite concentrate and flotation tailings?
Yes. Concentrate recovery and tailings thickening require different bowl speed, pond depth, and differential-speed settings.
Will flotation reagents affect separation performance?
Yes. Frothers, collectors, depressants, and dispersants may keep fine particles suspended. Slurry testing is recommended before model selection.
Can it reduce fluorite loss in process water?
Yes. The centrifuge captures suspended fluorite fines from washing water and classification overflow, helping improve overall material recovery.
How are quartz and silica impurities handled?
They are discharged with the solids, but their hardness can increase equipment wear. Carbide tiles or ceramic protection may be required.
Can the clarified water return directly to the flotation circuit?
Possibly. Residual reagents, suspended solids, and water chemistry should be checked before recycling to avoid affecting flotation performance.
