The Decanter Centrifuge for Mica Slurry Recovery is designed for continuous solid-liquid separation, mica fines recovery, slurry thickening, and process-water clarification.
It is suitable for mica powder processing, mica washing, mineral beneficiation, grinding and classification slurry, flotation tailings, and mica-containing wastewater. The centrifuge separates fine mica particles from the liquid phase and produces thickened mica solids for further filtration, drying, storage, or reuse. Clarified liquid can be recycled to washing, grinding, classification, or wastewater treatment.
| Process Requirement | Decanter Centrifuge Solution |
|---|---|
| Fine mica particle recovery | Continuous high-force separation |
| Large slurry volume | Continuous automatic operation |
| Variable slurry concentration | Adjustable bowl speed and differential speed |
| Water recycle | Clarified liquid for reuse or further treatment |
| Lower filtration load | Thickened slurry before filter press or dryer |
| Mineral impurity handling | Optional wear-resistant configuration |
| Reduced manual operation | PLC-controlled continuous discharge |
Peony provides continuous solid-liquid separation for mica slurry recovery, thickening, and process-water recycle.
Mica Washing / Grinding / Classification → Slurry Tank → Optional Flocculant Dosing → Decanter Centrifuge → Thickened Mica Solids → Filter Press / Dryer / Storage
Clarified Liquid → Process Water Tank → Recycle to Washing, Grinding, or Further Treatment
Peony can provide:
Mica 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 mica solids from the liquid phase.
Mica particles move outward and form a solids 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 mica 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 mica solids are discharged continuously from the solids outlet.
Recovered mica slurry can be transferred to a filter press, vacuum filter, dryer, storage tank, or further classification process.

The decanter is suitable for fines, suspended plastic particles, sludge, labels, fibers, and mixed contaminants. Large flakes and film pieces should usually be screened or mechanically dewatered before entering the decanter.
Plastic washing slurry may contain sand, glass fines, or mineral particles. Wear protection is recommended when abrasive solids are present.
Polymer can improve recovery of fine suspended solids, but dosage should be tested to avoid excessive chemical use or negative effects on water recycle.
For direct reuse in sensitive washing stages, additional polishing filtration or treatment may be required after decanter separation.
The decanter provides continuous thickening and primary dewatering. A filter press or dryer may be added where lower final moisture is required.
The decanter continuously recovers mica fines from slurry and process water, reducing material loss and improving solids handling.
Bowl speed, differential speed, pond depth, and feed rate can be adjusted according to mica particle size, feed concentration, and required recovery target.
Clarified liquid can be reused in washing, grinding, classification, or slurry preparation, helping reduce fresh-water use and wastewater discharge.
The centrifuge thickens mica slurry before filter pressing or drying, reducing liquid volume and improving downstream handling efficiency.
If the slurry contains quartz, silica, sand, or other abrasive minerals, wear protection can be added to the scroll, feed zone, and solids discharge area.
Please provide the following information for a suitable mica slurry recovery solution:
Yes. It can continuously recover fine mica solids from slurry and process water. For very fine particles, flocculant testing may be recommended.
Yes. Clarified liquid can often be returned to washing, grinding, classification, or process-water storage. Further treatment may be added if higher water quality is required.
It depends on the impurity content. If the mica slurry contains quartz, silica, sand, or hard mineral particles, wear protection is recommended.
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.
For coarse mica flakes, screening or other mechanical separation may be needed first. The decanter is more suitable for fine mica slurry, suspended solids, and process-water clarification.
