The Decanter Centrifuge for Quartz Powder Slurry Dewatering is designed for continuous quartz solids recovery, slurry thickening, filter-feed preparation, and process-water clarification.

It is suitable for quartz powder washing, wet grinding, classification overflow, silica sand processing, engineered-stone wastewater, and high-purity quartz production.

• Quartz powder washing slurry dewatering
• Wet grinding slurry treatment
• Classification overflow recovery
• Fine quartz particle recovery
• Silica sand washing-water clarification
• High-purity quartz slurry thickening
• Engineered stone polishing wastewater treatment
• Filter press feed preparation
• Process-water recycling
• Quartz tailings slurry treatment

Severe Abrasive Wear

Quartz particles can quickly wear the feed accelerator, scroll flights, bowl beach, and solids-discharge ports.

Recommended protection may include:

• Tungsten carbide scroll tiles
• Ceramic feed-zone liners
• Replaceable discharge inserts
• Hard-faced conveyor surfaces
• Protected solids outlets

The final protection material should match the required product-purity standard.

Fine and Slow-Settling Particles

Ultrafine quartz and clay particles may remain suspended in the liquid.

Higher centrifugal force, stable feeding, and suitable slurry conditioning may improve recovery. When very clear water is required, polishing filtration may still be needed.

High Slurry Density

Quartz slurry can produce high conveyor torque, especially when the feed concentration changes suddenly.

An agitated buffer tank, flow-controlled pump, and automatic torque adjustment help prevent overload and unstable solids discharge.

Product Contamination

For high-purity quartz, the internal material and wear-protection system must be selected carefully.

Metallic hard-facing may provide strong wear resistance but may not suit applications with strict contamination limits. Ceramic or customized protection can be considered.

Clay and Mica Content

Clay, mica, and other plate-like fines can affect slurry viscosity, liquid clarity, and discharged-solids handling.

Upstream desliming or laboratory testing is recommended when the fine impurity content is high.

Peony provides continuous separation solutions for quartz powder recovery, slurry thickening, filter press feed preparation, and process-water recycling.

Abrasion-Resistant Quartz Handling

Protected feed, conveying, and discharge areas help extend service life under high-silica conditions.

Fine Quartz Powder Recovery

The centrifuge recovers suspended quartz solids from washing water, grinding slurry, and classification overflow.

Stable Filter Press Feed

Continuous thickening provides a more consistent feed concentration and reduces hydraulic fluctuations.

Reduced Process-Water Consumption

Clarified liquid can be returned to quartz washing, grinding, or slurry preparation when its quality is acceptable.

Flexible Purity Configuration

Wetted materials and wear components can be selected according to standard industrial quartz or high-purity quartz requirements.

Please provide:

• Quartz product type and purity grade
• Slurry source and process stage
• Particle-size distribution
• Percentage of particles below 10 μm
