The Decanter Centrifuge for Gypsum Slurry Dewatering is designed for continuous solid-liquid separation, gypsum recovery, slurry thickening, and process-water clarification.
It is suitable for FGD gypsum, phosphogypsum, chemical gypsum, gypsum washing slurry, neutralization slurry, and other calcium sulfate suspensions. The centrifuge separates gypsum crystals, fine mineral particles, fly ash, unreacted limestone, and suspended impurities from the liquid phase.
| Process Requirement | Decanter Centrifuge Solution |
|---|---|
| Continuous gypsum recovery | Continuous feeding and solids discharge |
| Variable slurry concentration | Adjustable bowl and differential speed |
| Fine gypsum particles | High centrifugal force separation |
| Stable slurry thickening | Controlled feed rate and pond depth |
| Lower filtration load | Pre-thickening before filter or dryer |
| Process-water recycling | Clarified liquid for reuse or treatment |
| Abrasive impurities | Optional wear-resistant configuration |
| Automatic operation | PLC and VFD-controlled continuous running |
Peony provides continuous separation solutions for gypsum slurry dewatering, solids recovery, slurry thickening, and process-water recycling.
FGD / Phosphogypsum / Chemical Gypsum Process
→ Agitated Slurry Tank
→ Optional Flocculant Dosing
→ Decanter Centrifuge
→ Thickened Gypsum Solids
→ Filter Press / Vacuum Belt Filter / Dryer / Storage
Clarified Liquid
→ Process-Water Tank
→ Recycle or Further Treatment
Gypsum slurry enters the rotating bowl through a controlled feed pipe.
An agitated tank is normally used to prevent crystal settling and maintain a stable feed concentration.
High-speed rotation separates gypsum crystals and suspended solids 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.
The internal screw conveyor rotates at a controlled differential speed.
It continuously transports the settled gypsum solids toward the conical end for further dewatering.
The separated liquid leaves through the liquid outlet.
It can be returned to the process-water system or transferred to further clarification and wastewater treatment.
Concentrated gypsum solids are discharged continuously.
The recovered gypsum can be sent to a filter press, vacuum belt filter, dryer, storage system, or further processing stage.

FGD gypsum, phosphogypsum, and chemical gypsum have different particle sizes, impurities, pH values, and corrosion conditions. The exact slurry source should be confirmed before selection.
Coarser gypsum crystals normally settle more easily. Fine crystals or irregular particles may require higher centrifugal force or flocculant dosing.
Feed concentration affects throughput, torque, liquid clarity, and discharged-solids concentration. Stable feeding helps maintain consistent operation.
FGD and phosphogypsum slurry may contain chlorides, fluorides, acids, or other corrosive components. Liquid composition and temperature should be provided for material selection.
Silica, fly ash, sand, unreacted limestone, and mineral impurities may increase wear in the feed zone, scroll, and solids outlet.
Flocculant may improve fine-particle capture and liquid clarity. Laboratory testing is recommended before confirming the dosing system.
The centrifuge continuously separates gypsum crystals from the slurry, reducing product loss and avoiding frequent batch interruptions.
Bowl speed, differential speed, pond depth, and feed rate can be adjusted according to gypsum crystal size and slurry concentration.
The high centrifugal force removes free liquid from gypsum solids and improves the feed condition for further filtration or drying.
Clarified liquid can be recycled to washing, slurry preparation, or other production stages when it meets the process requirement.
Optional wear-resistant and corrosion-resistant components support reliable operation with silica, fly ash, chlorides, fluorides, and other impurities.
Please provide:
Yes. It can continuously separate gypsum crystals from desulfurization slurry and recover clarified process liquid.
Yes. Material selection should consider acidity, fluoride, chloride, and other corrosive components in the slurry.
It depends on the impurity content. Wear protection is recommended when the slurry contains silica, fly ash, sand, or other abrasive solids.
Yes. Clarified liquid can often be returned to the process-water system or sent to further treatment.
Not always. It depends on gypsum particle size, fine-particle content, slurry concentration, and the required liquid clarity.
Peony welcomes cooperation with power plants, phosphoric acid plants, chemical gypsum producers, desulfurization contractors, wastewater treatment companies, distributors, and industrial separation partners.
We support partners with slurry testing, centrifuge selection, corrosion-resistant material selection, wear-resistant configuration, flocculant dosing, process-water recycling, installation guidance, commissioning, spare parts, and after-sales service.
Send us your gypsum slurry information, including slurry type, particle size, solids concentration, required capacity, liquid composition, clarified-liquid target, and downstream arrangement. Our engineering team will recommend a suitable decanter centrifuge solution for your gypsum slurry dewatering process.
