Materials
The Critical Separation Stage in PVC Processing
PVC (white/pale-yellow thermoplastic powder). In suspension process, the post-polymerization PVC-and-water slurry is separated to recover resin and cut moisture for drying — the centrifuge drives yield, moisture, and drying energy.
Why Separation
Performance Matters？
In PVC production, the centrifuge does more than “separate the particles” — it also affects particle moisture, liquid entrainment, PVC recovery, drying load, and equipment corrosion life.
High Moisture
Wet PVC particles increase downstream drying load and energy use.
Fine Particle Loss
Fine powder lost with the liquid phase lowers product recovery.
Corrosion Risk
PVC mother liquor is corrosive — ordinary stainless steel can’t sustain long-term operation.
Continuous Production
Scaled production needs continuous feed, separation, and discharge — equipment stability directly sets capacity.
One Process. Two Separation Solutions.
For varying slurry concentrations and process fluctuations after PVC polymerization, two continuous separation options are offered: LWL and LWLZ.
LWL
Continuous Screen Filtration
Screw Conveying
Deliquoring
Continuous solid-liquid separation of PVC particles from the liquid
phase — suited to conventional solids-bearing slurries.
Which one
fits your
process?
LWLZ
Sedimentation Thickening
Screen Filtration
PVC slurries with low solids or high fines — thicken first, then filter.
LWL Horizontal Screen Scroll Centrifuge
Continuous solid-liquid separation equipment for PVC particles and liquid phase.
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
Multi-stage filtering centrifuge: continuous feed, wash/dewater. LWLZ’s two-stage thicken-then-filter handles low-solids/fines PVC slurry efficiently.
Handles Varying Slurry Concentrations
Low-solids feed is pre-thickened before the filtration stage.
Suited to Fine-particle Materials
Solid-liquid separation in two stages: sedimentation and filtration.
Combines Thickening And Filtration
Front stage handles liquid-solid separation; rear stage further filters and deliquors.
Continuous Production
Suited to continuous production.
Washing Can Be Added
A washing device can be added during filtration according to product purity requirements.
LWLZ Series
LWL or LWLZ?
How to choose the right PVC centrifuge for you?
| Comparison Criteria | LWL | LWLZ |
|---|---|---|
| Feed Concentration | Conventional Solid-bearing Crystal Slurry | Low Solids, High Mother Liquor Volume, Fluctuating Concentration |
| Separation Method | Screen Filtration + Screw Deliquoring | Sedimentation Thickening + Screen Filtration |
| Fine-particle Adaptability | Depends On Screen Matching | Sedimentation Stage Enhances Fine-particle Capture |
| Product Integrity | Relatively Good | The Sedimentation Stage May Cause Slight Crystal Breakage |
| Typical Applications | PVC Conventional Particle Separation | Dilute, Fine-powder PVC Slurries Needing Pre-thickening |
