The Decanter Centrifuge for Stone Cutting Slurry Dewatering is designed for continuous stone-powder separation, sludge thickening, filter press feed preparation, and cutting-water clarification.

It is suitable for granite, marble, quartz stone, engineered stone, ceramic slab, and artificial stone processing wastewater generated during sawing, cutting, grinding, and polishing.

• Granite cutting slurry dewatering
• Marble sawing wastewater treatment
• Engineered quartz stone slurry treatment
• CNC stone-processing wastewater
• Bridge saw cooling-water clarification
• Grinding and polishing slurry thickening
• Ceramic and sintered-stone wastewater
• Settling pond sludge treatment
• Filter press feed preparation
• Stone powder recovery
• Cutting-water recycling
• Stone-processing wastewater pretreatment

Coarse Stone Chips

Stone-processing wastewater may contain coarse chips, broken fragments, wire-saw pieces, and other foreign objects.

Screening, grit removal, or desanding is recommended before centrifugation to protect the feed pipe, scroll, and solids outlets.

High Abrasive Wear

Granite and engineered quartz slurry may contain hard quartz, feldspar, silica, and polishing abrasives.

Recommended protection may include:

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

Changing Slurry Concentration

Slurry concentration can change significantly when several cutting or polishing machines discharge into the same collection tank.

An agitated buffer tank, regulated feed pump, and automatic torque control help maintain stable operation.

Fine Marble and Polishing Powder

Fine calcium carbonate, silica, and polishing particles may remain suspended and reduce clarified-water quality.

Flocculant dosing or downstream polishing filtration may be required when cleaner recycled water is needed.

Resin and Processing Additives

Engineered-stone slurry may contain resin, pigments, coolants, waxes, surfactants, and polishing chemicals.

The slurry composition should be checked before selecting seals, wetted materials, and cleaning arrangements.

Peony provides continuous separation solutions for stone-powder recovery, sludge thickening, filter press feed preparation, and cutting-water recycling.

Abrasion-Resistant Stone Slurry Handling

Protected feed, conveying, and discharge areas support continuous operation with granite, quartz, silica, and polishing abrasives.

Continuous Cutting-Water Recovery

Clarified water can be returned to cutting, grinding, or polishing equipment when it meets the required quality.

Stable Filter Press Feed

Continuous pre-thickening provides a more consistent sludge concentration and reduces hydraulic fluctuations.

Reduced Settling Pond Load

The centrifuge separates stone powder continuously, reducing sludge accumulation and dependence on large settling ponds.

Easier Sludge Handling

Thickened stone sludge occupies less volume and is easier to pump, transport, filter, dry, or dispose of.

Please provide:

• Stone type and processing stage
• Particle size and solids concentration
• Slurry density and viscosity
• Required capacity and water clarity
• Abrasive content and chemical additives
• Pretreatment and downstream filter press arrangement

Peony welcomes distributor and agent cooperation with granite and marble factories, engineered-stone manufacturers, ceramic slab plants, stone fabrication workshops, stone-water-treatment contractors, and industrial separation partners.

We support partners with stone slurry testing, centrifuge selection, coarse-particle pretreatment, wear-resistant configuration, cutting-water recycling, filter press integration, installation guidance, commissioning, spare parts, and after-sales service.

Send us your stone slurry information, including stone type, particle size, solids concentration, required capacity, abrasive content, water-reuse requirement, and downstream sludge-handling arrangement. Our engineering team will recommend a suitable decanter centrifuge solution for your stone cutting slurry dewatering process.
