The Decanter Centrifuge for Talc Slurry Recovery is designed for continuous solid-liquid separation, talc powder recovery, slurry thickening, and process-water clarification.
It is suitable for talc powder processing, talc washing, grinding slurry, classification overflow, mineral beneficiation wastewater, and fine talc recovery from process water. The centrifuge separates talc solids, fine mineral particles, clay, and suspended impurities from the liquid phase.

|---|---|
| Fine talc recovery | Continuous high-force separation |
| Process-water recycle | Clarified liquid for reuse or treatment |
| Variable slurry concentration | Adjustable bowl speed and differential speed |
| Flake-like particles | Stable thickening with controlled feed |
| Lower filtration load | Thickened slurry before filter press or dryer |

| Automatic operation | PLC-controlled continuous running |
Peony provides continuous solid-liquid separation for talc slurry recovery, slurry thickening, and process-water recycle.
Talc Grinding / Washing / Classification → Slurry Tank → Optional Flocculant Dosing → Decanter Centrifuge → Thickened Talc Solids → Filter Press / Dryer / Storage / Regrinding
Clarified Liquid → Process Water Tank → Recycle to Washing, Grinding, or Further Treatment
Peony can provide:
Talc slurry enters the rotating bowl through a controlled feed pipe.
An agitated slurry tank is normally recommended upstream to prevent settling and maintain stable feed concentration.
Inside the high-speed rotating bowl, centrifugal force separates talc solids and fine mineral particles from the liquid phase.
The 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 relative to the bowl.
This movement transports settled talc solids toward the conical end for continuous discharge.
The separated liquid leaves through the liquid outlet.
It can be returned to washing, grinding, classification, process-water recycle, or further wastewater treatment.
The concentrated talc solids are discharged continuously from the solids outlet.
Recovered talc slurry can be transferred to a filter press, dryer, storage tank, regrinding system, or further classification process.

Fine talc particles may settle slowly, especially when the slurry contains clay or ultrafine mineral solids. Particle-size distribution should be checked before selection.
Talc particles often have a plate-like or flaky structure. This may affect slurry flowability, cake formation, and solids discharge behavior.
High solids concentration or high viscosity may reduce throughput. Stable feeding helps maintain consistent separation performance.
Quartz, silica, sand, carbonate minerals, and clay content can affect wear, separation efficiency, and clarified-water quality.
Flocculant may improve fine-particle capture and liquid clarity. Slurry testing is recommended before confirming the dosing system.
The decanter continuously recovers fine talc solids from washing water, grinding slurry, and classification overflow, helping reduce product loss.
Bowl speed, differential speed, pond depth, and feed rate can be adjusted according to slurry concentration, particle size, viscosity, and required recovery rate.
Clarified liquid can be reused in washing, grinding, classification, or slurry preparation, helping reduce fresh-water consumption and wastewater discharge.
The centrifuge thickens talc slurry before filter pressing or drying, reducing liquid volume and improving downstream handling efficiency.
Talc itself is relatively soft, but the slurry may contain quartz, silica, sand, or other hard mineral impurities. Wear protection can be added where required.
Please provide the following information for a suitable talc slurry recovery solution:
Yes. It can continuously recover fine talc solids from washing water, grinding slurry, and classification overflow.
It depends on the impurity content. If the talc slurry contains quartz, silica, sand, or other abrasive minerals, wear protection is recommended.
Yes. Clarified liquid can often be returned to washing, grinding, classification, or slurry preparation.
Not always. It depends on particle size, fine content, slurry concentration, and clarified-water target.
The decanter is mainly used for continuous thickening and primary dewatering. A filter press or dryer may still be needed when lower final moisture is required.
