The Critical Separation Stage in Cellulose Ether Processing
Cellulose ethers (HPMC, HEC, CMC) from natural cellulose via alkalization and etherification. Their etherification or washing slurry needs solid-liquid separation to recover product, reduce residual liquor, and prep for drying.
Why Separation
Performance Matters？
In cellulose ether production, the centrifuge does more than “separate solids” — separation performance also affects product moisture, mother liquor entrainment, recovery rate, drying load, and equipment stability.
High Liquid Ratio
High liquid content after etherification/washing — pure-filtration units overload the screen, drain slowly.
Fine Particles
Cellulose ether particles are fine — wrong screen choice lets product escape with the liquor, lowering recovery.
High Viscosity
HEC, CMC and other high-viscosity slurries dewatered poorly — high moisture raises drying energy.
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 in cellulose ether production, two continuous separation options are offered: LWL and LWLZ.
LWL
Continuous Screen Filtration
Screw Conveying
Deliquoring
Continuous solid-liquid separation of cellulose ether solids from liquidmedium — suited to conventional solids-bearing slurries.
Which one
fits your
process?
LWLZ
Sedimentation Thickening
Screen Filtration
High-liquid, low-solids slurries needing pre-thickening before filtration.
LWL Horizontal Screen Scroll Centrifuge
Continuous solid-liquid separation equipment for cellulose ether solids and liquid medium.
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; 0.3–5 mm particles, fibrous & settled solids.
Handles Low-concentration Feed
Sedimentation pre-thickens — far less liquid reaches the filtration stage.
Higher Separation Efficiency
Most mother liquor is discharged before the filtration stage — more thorough removal and lower crystal moisture.
Screen Load Significantly Reduced
Far less liquid enters the filtration stage with the solids — less screen wear, longer service life.
Continuous Production
Continuous feed, continuous separation, continuous discharge.
Adjustable Differential Speed And Materials
Key parts in corrosion-resistant materials: 2205 duplex, 316L stainless.
LWLZ Series
LWL or LWLZ?
How to choose the right cellulose ether 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 | HPMC, HEC, CMC — Conventional Separation | Dilute, Fine-particle Slurries Needing Pre-thickening |
