The Critical Separation Stage in Sodium Carbonate Processing
Soda ash (Na₂CO₃): white, soluble, alkaline; produced as crystal slurry via ammonia/combined/natural soda routes, crystals separated for calcination. Centrifuges split crystals/mother liquor, driving yield, moisture, and calcination energy.
Why Separation
Performance Matters？
In soda ash production, centrifuges do more than separate crystals; separation also affects moisture, mother liquor entrainment, recovery, calcination load, and corrosion/maintenance.
High Moisture
Wet crystals increase downstream drying load and energy use.
Fine Crystal Loss
Fines lost with mother liquor reduce product recovery.
Alkali Corrosion
Alkaline Na₂CO₃ corrodes stainless steel, reducing equipment life and purity.
Continuous Production
Scaled production needs continuous feed, separation, and discharge — equipment stability directly sets capacity.
One Process. Two Separation Solutions.
For varying crystal slurry concentrations and fluctuating conditions after sodium carbonate crystallization, two continuous centrifugal separation solutions—LWL and LWLZ—are available.
LWL
Centrifugal Filtration
Screen Separation
Screw Differential Conveying
Conventional solids-containing crystal slurry: continuous separation with screen retention of crystals.
Which one
fits your
process?
LWLZ
Sedimentation Thickening
Screen Filtration
Low solids, fine particles, fluctuating concentration; pre-concentration before filtration required.
LWL Horizontal Screen Scroll Centrifuge
Continuous crystal/mother-liquor separation; proven for soda ash, sodium sulfate, oxalic acid, Glauber’s salt, citric acid, crystalline soda, thiosulfate.
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
Continuous feed, washing/dewatering; 0.1–10 mm (mainly 0.3–2 mm). Low-solids/fine
Na₂CO₃: LWLZ pre-concentration + filtration; also Na₂SO₄, crystalline soda.
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 Select the Right Centrifuge for Your Sodium Carbonate (Soda Ash) Application?
| Comparison Criteria | LWL | LWLZ |
|---|---|---|
| Feed Concentration | Conventional Solid-bearing Crystal Slurry | Low Solids, Highly Variable Concentration |
| Separation Method | Screen Filtration + Screw Deliquoring | Sedimentation Thickening + Screen Filtration |
| Fine-particle Adaptability | Dependent on Proper Screen Matching | Enhanced fine-particle capture in the sedimentation zone |
| Crystal Integrity | Relatively Good | Slight crystal breakage possible in the sedimentation zone |
| Typical Applications | Continuous Crystallized-salt Separation | Dilute slurry, fine crystals, pre-concentration required |
