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.

How the Decanter Centrifuge Works
1. Stone Cutting Slurry Feeding
Screened stone slurry enters the rotating bowl through a controlled feed pipe.
An agitated tank prevents stone powder from settling and maintains a stable feed concentration.
2. Centrifugal Sedimentation
High-speed rotation separates stone powder and mineral particles from the water phase.
The denser solids move outward and form a layer against the bowl wall, while clarified water remains closer to the center.
3. Continuous Solids Conveying
The internal screw conveyor rotates at a controlled differential speed.
It continuously transports settled stone sludge toward the conical end for further dewatering.
4. Clarified Water Discharge
The separated water leaves through the liquid outlet.
It can be returned to cutting or polishing machines, sent to polishing filtration, or transferred to further wastewater treatment.
5. Thickened Stone Sludge Discharge
Concentrated stone sludge is discharged continuously.
The solids can be sent to a filter press, sludge container, drying system, disposal area, or suitable reuse process.

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
Can the same centrifuge process granite and marble slurry?
Yes, but the operating settings may differ. Granite slurry is usually more abrasive, while marble slurry often contains finer calcium carbonate particles.
Must stone chips be removed before feeding?
Yes. Coarse fragments, wire pieces, and foreign objects should be removed by screening or desanding before the slurry enters the centrifuge.
Can clarified water be reused by cutting machines?
Yes, when its suspended-solids level and particle size meet the machine requirements. Additional polishing filtration may be needed for cleaner water.
Can the recovered stone powder be reused?
It depends on the stone type, particle size, purity, color, and chemical additives. Separate slurry collection is recommended when powder reuse is planned.
Does engineered-stone slurry require special configuration?
It may. Resin, pigments, surfactants, and polishing chemicals can affect separation, cleaning, and seal compatibility. Slurry testing is recommended.
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.
