Decanter Centrifuge for Talc Slurry Recovery

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.

• Talc slurry recovery
• Talc powder washing-water clarification
• Fine talc particle recovery
• Grinding and classification slurry treatment
• Talc beneficiation wastewater treatment
• Filter press feed thickening
• Process-water recycle in talc plants
• Clay and mineral impurity removal
• Fine mineral slurry thickening

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:

• Decanter centrifuge selected according to talc slurry condition
• Agitated slurry buffer tank for stable feeding
• Controlled feed pump and flow regulation system
• Optional flocculant dosing and mixing system
• Adjustable differential speed and pond depth control
• Wear-resistant scroll and solids-discharge configuration when required
• Clarified liquid collection and recycle connection
• PLC and VFD automatic control system
• Connection to filter press, dryer, storage tank, or wastewater treatment system

Particle Size and Fine Content

Fine talc particles may settle slowly, especially when the slurry contains clay or ultrafine mineral solids. Particle-size distribution should be checked before selection.

Flake-Like Particle Shape

Talc particles often have a plate-like or flaky structure. This may affect slurry flowability, cake formation, and solids discharge behavior.

Slurry Concentration and Viscosity

High solids concentration or high viscosity may reduce throughput. Stable feeding helps maintain consistent separation performance.

Impurity Content

Quartz, silica, sand, carbonate minerals, and clay content can affect wear, separation efficiency, and clarified-water quality.

Flocculant Compatibility

Flocculant may improve fine-particle capture and liquid clarity. Slurry testing is recommended before confirming the dosing system.

Continuous Talc Powder Recovery

The decanter continuously recovers fine talc solids from washing water, grinding slurry, and classification overflow, helping reduce product loss.

Stable Slurry Thickening

Bowl speed, differential speed, pond depth, and feed rate can be adjusted according to slurry concentration, particle size, viscosity, and required recovery rate.

Process-Water Recycle

Clarified liquid can be reused in washing, grinding, classification, or slurry preparation, helping reduce fresh-water consumption and wastewater discharge.

Lower Downstream Load

The centrifuge thickens talc slurry before filter pressing or drying, reducing liquid volume and improving downstream handling efficiency.

Optional Wear Protection

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:

• Talc process stage
• Particle-size distribution
• Fine-particle and clay content
• Slurry solids concentration
• Slurry density and viscosity
• Required processing capacity
• Required talc recovery rate
• Target solids concentration after centrifugation
• Clarified-water quality requirement
• Process-water recycle requirement
• Quartz, silica, sand, or abrasive impurity content
• Flocculant or polymer currently used
• Downstream filter press, dryer, storage, or regrinding arrangement
• Required material of construction
• Electrical and control standard

Peony welcomes distributor and agent cooperation with talc processing plants, talc powder manufacturers, mineral beneficiation companies, grinding-system contractors, wastewater treatment companies, and industrial separation partners.
