Applications
Sedimentation and Filtration Centrifuge: industrial applications
Applications include inorganic salts and chemical and polymer processing. Confirm material properties and process conditions before selecting the equipment configuration.
Chemical and polymer processing
Nitrocellulose, biodegradable plastics and CPE insulation-material production streams.
Crystalline and particulate feeds
Settleable crystals and granular suspensions requiring further filtration after concentration.
Fibrous and complex suspensions
Fibrous feeds and materials containing a limited organic or viscous fraction, including tar-bearing streams, subject to testing.
Industrial sectors
Chemical, pharmaceutical, environmental, food, mining and energy applications.
Working Principle
From feed preparation to finished product.
The process route is selected around the material and product targets.
Continuous feed
Feed enters the high-speed rotating bowl and is distributed into the sedimentation zone.
Centrifugal sedimentation
The density difference causes solids to settle rapidly against the bowl wall while the clarified liquid forms an inner layer.
Scroll conveying
A differential-speed scroll transports the concentrated solids continuously toward the conical end.
Filtration and final dewatering
The solids enter the filtration section, where residual liquid passes through the filter medium for additional dewatering.
Continuous phase discharge
Dewatered solids leave through the conical-end discharge, while clarified liquid exits from the large-diameter end.
Performance Highlights
Process performance shaped around the product.
Final performance remains dependent on feed properties and engineering confirmation.
Combined separation modes
Primary sedimentation concentrates the solids; secondary filtration removes additional liquid before discharge.
Improved dewatering
The filtration section can reduce residual liquid in the solids compared with sedimentation alone.
Broad feed compatibility
Suitable feeds include settleable crystalline, granular and fibrous suspensions, subject to process evaluation.
Large L/D design
The bowl length supports effective settling residence time, high throughput and reduced solids carryover in the clarified liquid.
High product recovery
The operating range is selected for the material and confirmed for the quoted configuration.
Flexible differential control
Dual-motor, dual-VFD control enables adjustment of solids residence time and scroll conveying rate.
Energy-efficient drive option
A common-DC-bus regenerative system can recover usable energy and reduce overall electrical demand.
Long-life wear protection
Replaceable wear components protect the bowl, scroll flights, feed zone and solids outlets in abrasive service.
System Configuration
Standard process path with project-specific options.
Core equipment and auxiliary systems are selected around the process duty.
Combined separation bowl
The rotating assembly integrates a sedimentation zone for primary clarification and a filtration zone for secondary dewatering.
Dual-motor, dual-VFD drive
Separate drives for the bowl and scroll enable responsive differential-speed adjustment as feed conditions change.
Common DC bus
An optional common-DC-bus regenerative drive recovers part of the energy generated during differential or braking operation.
Optimized scroll geometry
The flow path reduces feed impact, buildup, blockage, friction and conveying torque while supporting low solids carryover.
Centrifugally cast rotating parts
Critical bowl and scroll-shaft components use centrifugal casting for material integrity, strength and reliable high-speed operation.
Wear-resistant scroll flights
Depending on abrasiveness, scroll flights can use hardfaced carbide, embedded carbide blocks or wear-resistant ceramic tiles.
High-strength self-cooling bearing housing
The rigid bearing housing supports efficient heat dissipation and stable long-term continuous operation.
Replaceable wear protection
Protected feed and solids-discharge zones, bowl wear features and replaceable outlet liners extend service life and simplify maintenance.
