Applications
Thickening and Filtration Screen-Worm Centrifuge: industrial applications
Applications include crystalline and granular products and fibrous and agricultural materials. Confirm material properties and process conditions before selecting the equipment configuration.
Fibrous and agricultural materials
Fibrous solids, crop hulls and similar materials with suitable filtration behavior.
Polymer products
Plastic particles and related process solids requiring continuous separation and dewatering.
Low-solids and fines-bearing feeds
Mother liquors with low solids concentration, a proportion of fine particles or a limited amount of viscous material.
Industrial sectors
Chemical, food, salt, mining and pharmaceutical processing.
Working Principle
From feed preparation to finished product.
The process route is selected around the material and product targets.
Feed and pre-thickening
Feed enters the inner scroll and is distributed into the high-speed sedimentation section, where most of the liquid is separated from the solids.
Clarified-liquid discharge
The substantially clarified liquid exits through an adjustable bowl-overflow arrangement that sets pond depth and thickening conditions.
Secondary filtration
The internal scroll continuously conveys the concentrated suspension into the screen section, where residual liquid passes through the filter medium.
Washing and final dewatering
An optional wash pipe can provide a simple solids wash before centrifugal dewatering is completed.
Continuous solids discharge
The outer scroll transports the dewatered solids continuously into the discharge chamber.
Filtrate management
Filtrate may be discharged separately, recirculated or combined with another liquid stream; an optional gas–liquid separator supports stable drainage.
Performance Highlights
Process performance shaped around the product.
Final performance remains dependent on feed properties and engineering confirmation.
Integrated pre-thickening
Centrifugal sedimentation removes most of the liquid before the solids reach the screen.
Efficient low-solids processing
Pre-concentration improves screen loading and makes the machine suitable for feeds with low initial solids.
Fine-particle recovery
The combined route supports recovery of fines that can be difficult for filtration-only machines.
Low residual moisture
Secondary screen filtration and centrifugal dewatering reduce liquid remaining in the discharged solids.
High continuous capacity
Continuous feed, separation and discharge support high throughput with strong conveying torque and reduced blockage risk.
Closed, energy-efficient operation
An enclosed structure, VFD control, low vibration and low noise support efficient production with reduced emissions.
High automation
PLC control and optional adaptive hydraulic differential compensation respond to changing equipment load and separation conditions.
Flexible corrosion resistance
A broad selection of stainless steels, duplex alloys, titanium and nickel alloys supports corrosive or hygiene-sensitive duties.
Multiple safety protections
Machine-condition monitoring and project-specific interlocks support reliable long-term operation.
System Configuration
Standard process path with project-specific options.
Core equipment and auxiliary systems are selected around the process duty.
Two-stage rotating assembly
A sedimentation pre-thickener removes bulk liquid before the concentrated solids enter the screen-filtration section.
Adjustable liquid overflow
The overflow arrangement sets pond depth and allows the thickening condition to be matched to the feed.
Internal and outer scrolls
The internal scroll transfers concentrated solids to filtration, while the outer scroll conveys the dewatered product to discharge.
Differential-drive options
Multiple differential systems, including an optional hydraulic drive with adaptive compensation, can match scroll speed to process load.
Variable-speed automation
VFD control and PLC automation support stepless speed adjustment, load response and stable continuous operation.
Construction materials
The operating range is selected for the material and confirmed for the quoted configuration.
Process internals
Different filtration media, feed systems and lubrication arrangements are available to suit material and operating requirements.
Bowl cone angles
The operating range is selected for the material and confirmed for the quoted configuration.
Liquid-line options
Filtrate can be routed separately, recirculated or combined, with an optional gas–liquid separator for reliable drainage.
Safety and condition monitoring
Speed, vibration, motor overload and overtemperature, and bearing temperature can be monitored; hazardous-area protection is available where required.
