The Decanter Centrifuge for Pigment Slurry Dewatering is designed for continuous pigment recovery, slurry thickening, wash-water clarification, and filter-press feed preparation.
It is suitable for titanium dioxide, iron oxide, carbon black, inorganic pigments, mineral pigments, and compatible organic pigment slurries.
Many pigment particles are fine and remain suspended for long periods.
Higher centrifugal force, stable feeding, and optional coagulation or flocculation may improve recovery.
Dispersants, wetting agents, and surfactants can reduce particle settling.
The slurry chemistry should be tested before confirming the separation process.
Different pigment colors should normally be collected and treated separately when recovered solids will be reused.
Dedicated pipelines, flushing connections, and cleaning procedures help reduce cross-contamination.
Titanium dioxide, iron oxide, carbon black, and organic pigments have different densities and settling behavior.
Bowl speed, differential speed, pond depth, and feed rate should be adjusted for each material.
Mineral pigments and fillers may cause wear, while acidic or alkaline liquids may require corrosion-resistant wetted parts.
Carbide, ceramic, SS316L, duplex steel, or customized materials can be selected where required.
Peony provides continuous separation solutions for pigment recovery, slurry thickening, process-water clarification, and downstream filtration preparation.
Pigment Production / Washing / Classification
→ Separate Collection by Pigment Type
→ Agitated Slurry Tank
→ Optional pH Adjustment / Flocculation
→ Decanter Centrifuge
→ Thickened Pigment Solids
→ Filter Press / Dryer / Reprocessing / Storage
Clarified Liquid
→ Process-Water Tank
→ Recycle / Polishing Filtration / Further Treatment
Pigment slurry enters the rotating bowl through a controlled feed pipe.
An agitated tank prevents pigment settling and maintains a stable feed concentration.
High-speed rotation separates pigment particles and suspended solids from the liquid phase.
The denser solids move outward and form a layer against the bowl wall.
The internal screw conveyor rotates at a controlled differential speed.
It transports settled pigment solids toward the conical end for further thickening.
The separated liquid leaves through the liquid outlet.
It can be recycled, sent to polishing filtration, or transferred to further wastewater treatment.
Concentrated pigment solids are discharged continuously.
The recovered material can be sent to filter pressing, drying, reprocessing, storage, or controlled disposal.

Recovers suspended pigment solids and reduces valuable material loss.
Produces a more consistent feed concentration for filter presses or dryers.
Removes pigment solids before downstream water treatment.
Wear-resistant, corrosion-resistant, and low-contamination options are available.
PLC and VFD control support continuous and stable separation.
Please provide:
Yes, but separate collection and thorough flushing are recommended to reduce color cross-contamination.
Yes. It can thicken and recover titanium dioxide solids from washing or production slurry.
Yes, but low-density carbon black may require slurry testing and chemical conditioning.
No. It depends on particle size, slurry stability, dispersant content, and required liquid clarity.
Not always. Color strength, purity, particle size, contamination, and product quality should be tested before reuse.
Peony welcomes distributor and agent cooperation with pigment manufacturers, coating and ink producers, titanium dioxide plants, mineral-processing companies, wastewater contractors, and industrial separation partners.
We support partners with slurry testing, centrifuge selection, chemical-conditioning design, wear and corrosion protection, process-water recycling, filter press integration, commissioning, spare parts, and after-sales service.
Send us your pigment slurry information, including pigment type, particle size, solids concentration, required capacity, recovery target, purity requirement, and downstream arrangement. Our engineering team will recommend a suitable decanter centrifuge solution for your pigment slurry dewatering process.
