Applications
Flat-Plate Bag-Lifting Filtration Centrifuge: industrial applications
Applications include pharmaceuticals and food and ingredients. Confirm material properties and process conditions before selecting the equipment configuration.
Food and ingredients
Salt, monosodium glutamate, food additives, starch, sugar and formulated seasoning products.
Inorganic salts and chemicals
Gypsum, calcium sulfate, copper sulfate, potassium chloride, borax, dyes, pigments and pesticide products.
Minerals and metal refining
Copper, zinc and aluminum-bearing materials and other mineral or metallurgical suspensions after process review.
Environmental and energy
Sludge, wastewater solids and related process suspensions in environmental and energy applications.
Working Principle
From feed preparation to finished product.
The process route is selected around the material and product targets.
Feed and filtration
Suspension is charged into the rotating basket. Centrifugal force drives the liquid phase through the filter cloth and basket perforations, while solids form a cake on the basket wall.
Cake washing
When required, wash liquid is applied to the retained cake and removed through the same filtration path.
Final dewatering
The basket continues at the selected speed until the cake reaches the specified separation or residual-moisture target.
Controlled stop and access
After the basket has stopped, the cover is opened and the dedicated lifting device is positioned over the filter bag.
Whole-bag discharge
The hydraulic cantilever crane and special lifting tool remove the complete filter bag and transfer it to the discharge station, minimizing manual handling and crystal breakage.
Reset for the next batch
After discharge, the empty filter bag is reinstalled, the quick-release retaining plate is secured, and the cover is closed and interlocked for the next cycle.
Performance Highlights
Process performance shaped around the product.
Final performance remains dependent on feed properties and engineering confirmation.
Low-effort, high-efficiency discharge
The hydraulic cantilever crane lifts the complete filter bag with a dedicated tool, reducing manual effort and cycle time.
Gentle crystal handling
Whole-bag removal and off-machine discharge reduce direct scraping and help limit crystal breakage.
Smooth, adjustable operation
Variable-frequency speed control provides an adjustable separation factor, while hydraulic damping minimizes vibration.
Fast filter-cloth changeover
The quick-release liquid-retaining plate provides convenient access for filter-cloth removal and replacement.
Multiple safety protections
Nitrogen protection, vibration monitoring, cover-open protection, overload protection and electromechanical interlocks are available.
Flexible process options
Cake-layer control, atomized washing, CIP, explosion-proof illumination and hydraulic or assisted cover opening can be specified by project.
System Configuration
Standard process path with project-specific options.
Core equipment and auxiliary systems are selected around the process duty.
Hydraulic lifting system
Cantilever crane with a purpose-designed lifting tool for complete filter-bag removal and transfer.
Drive and vibration control
Variable-frequency drive provides smooth starting and adjustable centrifugal force; hydraulic dampers limit transmitted vibration.
Filter-bag retention
A quick-release liquid-retaining plate simplifies access and filter-cloth replacement.
Cleaning and washing
Optional cake-layer monitoring, atomized cake washing and CIP online cleaning can be integrated into the batch cycle.
Containment options
Nitrogen blanketing and an explosion-proof sight-glass light are available for hazardous or oxygen-sensitive duties.
Safety interlocks
Vibration, cover-open and overload protection are combined with electromechanical interlocks for controlled operation.
Cover operation
Hydraulic cover opening or mechanically assisted cover opening can be selected to suit the installation.
