Applications
Pull-Bag Scraper Bottom-Discharge 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 chemical-seasoning products.
Chemicals and new energy
Ammonium sulfate, gypsum, sodium sulfate, copper sulfate, potassium chloride, borax, dyes, pigments, resins, pesticides and lithium-battery precursor materials.
Minerals and environmental
Mining, metallurgy and environmental suspensions, including viscous, fine-particle, toxic or flammable feeds after review.
Working Principle
From feed preparation to finished product.
The process route is selected around the material and product targets.
Controlled feeding
Suspension enters the rotating basket through the feed pipe until the programmed charge is reached.
Filtration and dewatering
Liquid passes through the filter cloth and exits through the liquid outlet while solids form a cake.
Cake washing
Wash liquid is applied to the retained cake and removed through the filtration path.
Final spin
The basket continues rotating until the cake reaches the required separation target.
Scraper discharge
The centrifuge slows and the automatic scraper directs the cake through the bottom outlet.
Pull-bag regeneration
At lower speed, the pneumatic pull-bag device reciprocates to shake off residual cake and restore the filter cloth.
Performance Highlights
Process performance shaped around the product.
Final performance remains dependent on feed properties and engineering confirmation.
Process-specific construction
Select standard construction for general service, lined construction for product-contact requirements, hygienic full-cover access for cleaning, or insulation for temperature-controlled duty.
Stable foundation-free installation
Hydraulic vibration damping, a low center of gravity and flat-plate or box-base arrangements support stable operation and maintenance.
Smooth, uniform discharge
Adjustable scraper speed and distance, optional layered scraping and a streamlined feed distributor support controlled cake removal and balanced filling.
GMP, containment and safety
Smooth product-contact surfaces, CIP cleaning, nitrogen protection, speed and overload monitoring, interlocks and explosion-protection options support hygienic or hazardous duties.
System Configuration
Standard process path with project-specific options.
Core equipment and auxiliary systems are selected around the process duty.
Cover and base
Large-cover or full-flip-cover construction with flat-plate or box-base arrangements according to the selected pull-bag scraper centrifuge / hygienic pull-bag scraper centrifuge configuration.
Feed and discharge
Inclined-disc, side or center feeding with scraper-plus-pull-bag discharge for residual-cake removal.
Cleaning
CIP online cleaning, atomized spray washing, spray balls or pipes, filter-cloth washing and optional pulse cleaning.
Control and drive
PLC, HMI, variable-frequency control, energy-braking or dynamic-feedback braking with standard, efficient, VFD, explosion-proof or high-altitude motors.
Safety protection
Explosion protection, nitrogen blanketing and oxygen monitoring, vibration and temperature protection, interlocks, speed detection, overload and material-position monitoring.
Configuration options
Choose the construction for your process.
Standard, lined, hygienic and insulated configurations share scraper discharge followed by pull-bag regeneration.
Standard
Automatic batch filtration with scraper discharge and pull-bag regeneration.
Lined
Lined product-contact construction selected for the material and corrosion requirements.
Hygienic
Full-flip-cover access and smooth transitions support thorough chamber cleaning.
Insulated
Insulated construction supports separation at the specified operating temperature.
