Fully Enclosed Continuous Operation
The Critical Separation Stage in Polymer & Biopolymer Processing
After polymerization, modification/ synthesis, or biological fermentation, the slurry typically contains solvents, residual monomers, catalysts, salt impurities, and fine polymer particles. The centrifuge performs continuous solid-liquid separation, impurity washing, deep dewatering, and solvent recovery — directly affecting product purity, moisture content, ash content, and production stability.
Why Separation
Performance Matters？
In polymer and biopolymer production, the centrifuge does more than just “separate the solids.” Separation performance further affects: product yield, ash and impurity content, moisture content, drying energy consumption, molecular chain integrity, and production continuity.
High Moisture
Wet residue raises downstream disposal or resource-recovery cost.
Fine Slag Loss
Fine slag lost with salt liquor reduces solids recovery and contaminates the salt solution.
Chloride Corrosion
High chloride causes pitting corrosion — shortening equipment life.
AlN Hydrolysis
AlN hydrolyzes in water, releasing ammonia — oxygen monitoring or nitrogen purge needed.
One Process. Two Separation Solutions.
Two Models — Matched to Different Polymer & Biopolymer Slurries
LWL
Centrifugal Filtration
Screen Separation
Screw Differential Conveying
Synthetic polymer powder slurries: CPE, PVC, modified plastics, synthetic rubber, and other medium-fine particles
Which one
fits your
process?
LWLZ
Sedimentation Thickening
Screen Filtration
Fine particles, low solids, fragile, high-impurity materials: PLA, PHA, plant polysaccharides, bio-gums, etc.
LWL Horizontal Screen Scroll Centrifuge
Built for continuous synthetic polymer powder slurries — CPE, PVC, modified plastics, synthetic rubber. Fully enclosed, automatic: feed, filter, wash, dewater, discharge.
Corrosion-resistant Materials
Main parts—bowl, screw, etc. can be made of corrosion-resistant stainless steel or titanium alloy.
Filtration Screen
Dedicated filtration screen, 0.5mm thick—longer service life.
Adjustable Differential
Bowl speed is steplessly adjustable; screw differential speed adjustable in steps or steplessly.
Circulating Lubrication
Simple, reliable circulating lubrication — with pressure regulation, oil filtration, and water cooling.
Safety Protection
Speed, over-vibration, motor overload / overheat, and zero-differential protection.
LWL Series
LWLZ Horizontal Screen Decanter Centrifuge
Integrated thickening-filter centrifuge for fine, low-solids, fragile, high-impurity materials — solving tough separation of PLA, PHA, polysaccharides, bio-gums, and ultrafine polymers.
Gravity Discharge
Gravity discharge — minimal crystal breakage.
Deliquoring
Longer residence and deliquoring time — lower discharge moisture.
Fine Particles
Suited to fine-particle ammonium sulfate slurry.
Bowl Cone Angle
Bowl cone angle optimized at 25° for gravity-slide discharge.
Screen Slotting
Optimized screen slots improve fine-crystal retention.
LWLZ Series
LWL or LWLZ?
How to Choose the Right Centrifuge for Your Polymer Process?
| Comparison Criteria | LWL | LWLZ |
