drilling mud decanter centrifuge
,solid liquid centrifuge
The Industrial Decanter Centrifuge for High-Viscosity Slurry continuously separates suspended solids from thick, slow-flowing process slurries.
It is suitable for chemical, mineral, fermentation, coating, oil-processing, and industrial wastewater applications where high viscosity affects settling, feeding, and solids discharge.
- Thick chemical process slurry
- Resin and polymer wastewater sludge
- High-viscosity mineral slurry
- Fermentation and biomass residue
- Paint, pigment, and coating sludge
- Oil-coated industrial solids
- Concentrated mother liquor sludge
- Heated organic process slurry
Difficult Feeding
Thick slurry may flow unevenly or overload the centrifuge.
A positive-displacement pump and controlled feed system help maintain stable flow.
Slow Solids Sedimentation
High liquid viscosity reduces the settling speed of fine particles.
Heating, dilution, or flocculation may improve separation.
Sticky Solids Buildup
Resins, polymers, oils, and organic solids may adhere to internal surfaces.
Automatic flushing and suitable surface treatment reduce deposits.
High Scroll Torque
Dense, sticky solids require greater conveying torque.
Adjustable differential speed and torque protection support continuous discharge.
Variable Slurry Properties
Viscosity may change with temperature, solids content, and process conditions.
Feed conditioning and automatic parameter adjustment improve stability.

How the Decanter Centrifuge Works
1. Conditioned Feeding
Heated and homogenized slurry enters the rotating bowl.
2. Solids Sedimentation
Dense solids move outward and form a sediment layer.
3. Liquid Clarification
Separated liquid remains closer to the bowl center.
4. Solids Conveying
The scroll transports sticky solids toward the conical end.
5. Continuous Discharge
Clarified liquid and concentrated solids discharge separately.

Main Advantages
Stable Feeding of High-Viscosity Slurry
Agitated tanks, temperature control, and positive-displacement pumps maintain uniform feeding and reduce flow pulsation.
High-Torque Conveying of Sticky Solids
The scroll drive provides sufficient torque to discharge resinous, oily, polymer-rich, or highly concentrated solids continuously.
Improved Separation at Low Settling Velocity
Adjustable bowl speed, pond depth, and residence time help separate particles whose settling is slowed by high liquid viscosity.
Reduced Adhesion and Internal Buildup
Optional heating, polished wetted surfaces, and automatic flushing reduce slurry adhesion inside the bowl and solids-discharge area.
Automatic Response to Viscosity Changes
PLC control adjusts feed rate and differential speed according to torque, temperature, and solids-load changes to prevent overload.
Please provide:
- Operating viscosity and temperature
- Solids concentration and particle size
- Flow rate and density
- Slurry composition and stickiness
- Target solids dryness
- Clarified-liquid requirement
What viscosity can the centrifuge handle?
The limit depends on temperature, solids content, particle properties, and required capacity.
Is heating required before separation?
It is recommended when heating can reduce viscosity without damaging the product.
Which feed pump is suitable?
A screw, progressive-cavity, or other positive-displacement pump is usually preferred.
Can it handle sticky polymer or resin sludge?
Yes, but flushing, torque control, and feed-condition testing are important.
How can separation performance be improved?
Heating, controlled dilution, flocculant dosing, lower throughput, or parameter adjustment may be used.
