Applications
Continuous Horizontal Decanter Centrifuge with Scroll Discharge: industrial applications
Applications include environmental and wastewater and chemical and mineral processing. Confirm material properties and process conditions before selecting the equipment configuration.
Chemical and mineral processing
Dye and pigment classification, flotation-cleaned coal and coal-slurry dewatering, ore-slurry classification, kaolin and graphite sizing, and coal-tar separation.
Food and fermentation
Starch washing and dewatering, soybean and wheat protein dewatering, juice clarification, pulp-fiber dewatering, fish meal and fish processing, distillers-grain dewatering, and animal or vegetable oil clarification.
Pharmaceutical and biotechnology
Separation of mycelial solids from antibiotic fermentation broth and similar bioprocess suspensions.
Working Principle
From feed preparation to finished product.
The process route is selected around the material and product targets.
Feed distribution
Suspension enters through the feed pipe and is distributed into the central region of the rotating bowl.
Centrifugal sedimentation
The density difference between phases causes heavier solids to settle rapidly against the bowl wall while the liquid forms an inner layer.
Continuous solids conveying
A differential-speed scroll transports the settled solids from the cylindrical clarification zone toward the conical dewatering zone.
Conical-zone dewatering
As the solids travel up the cone, additional liquid drains from the sediment before continuous discharge through the small-end solids ports.
Clarified-liquid discharge
Clarified liquid flows toward the large end and leaves through adjustable overflow weirs or, where specified, a paring-disc pump.
Optional three-phase duty
With the appropriate bowl and liquid-discharge configuration, the same density-separation principle can be applied to solid-liquid-liquid separation.
Performance Highlights
Process performance shaped around the product.
Final performance remains dependent on feed properties and engineering confirmation.
Continuous automatic operation
Continuous feeding, separation and solids discharge eliminate routine batch unloading and suit industrial production lines.
Multiple separation functions
One platform can perform solid-liquid separation, dewatering, clarification, concentration and particle classification.
Continuous scroll discharge
The scroll transports sediment from the cylindrical section through the conical dewatering zone for uninterrupted solids removal.
Adjustable differential speed
Changing bowl-to-scroll differential speed controls conveying rate, solids residence time, throughput and cake dryness.
Broad feed compatibility
The series covers wastewater, sludge, mineral slurry, starch, protein, fermentation broth and oil-processing duties after material evaluation.
Two-phase separation
This page covers solid–liquid separation. Three-phase duties require a separately specified machine.
Compact integrated processing
Sedimentation, conveying and dewatering occur in one enclosed continuous machine.
Process-responsive control
Speed, differential, pond depth and discharge arrangements can be optimized for changing feed and product requirements.
System Configuration
Standard process path with project-specific options.
Core equipment and auxiliary systems are selected around the process duty.
Cylindrical-conical bowl
The cylindrical section provides clarification and sedimentation area, while the conical section lifts and dewaters the conveyed solids.
Differential-speed scroll
A controlled speed difference between bowl and scroll determines solids residence time, conveying rate, torque and discharge consistency.
Hydraulic differential option
The hydraulic differential housing rotates with the bowl while its splined rotor drives the scroll. A connected hydraulic power unit varies oil flow to adjust differential speed during operation.
Adjustable process performance
Differential-speed control can optimize solids residence time, discharge rate, throughput and final cake dryness as feed conditions change.
Liquid discharge options
Clarified liquid can leave through large-end overflow ports or an optional paring-disc pump; specialized configurations can support three-phase separation.
Wear and monitoring package
Feed-zone, scroll and solids-outlet protection, together with vibration, temperature, speed and torque monitoring, are selected for the actual duty.
