The Critical Separation Stage in Sodium Bicarbonate Processing
Baking soda (NaHCO₃): white, weakly alkaline; metathesis/carbonation slurry; centrifuges separate crystals/mother liquor, affecting yield, moisture, drying.
Why Separation
Performance Matters？
In sodium bicarbonate production, centrifuges do more than separate crystals; separation also affects moisture, mother liquor entrainment, recovery, drying 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.
Weak Alkali Corrosion
Weakly alkaline NaHCO₃ corrodes standard stainless steel over time, cutting 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 variable crystal slurry concentrations and fluctuating conditions after sodium bicarbonate crystallization, two continuous centrifugal separation options—LWL and LWLZ—are available.
LWL
Centrifugal Filtration
Screen Separation
Screw Differential Conveying
Conventional crystal slurry: continuous separation, crystals retained by screen.
Which one
fits your
process?
LWLZ
Sedimentation Thickening
Screen Filtration
Low solids, fine particles, variable concentration: pre-concentrate before filtration.
LWL Horizontal Screen Scroll Centrifuge
Continuous solid–liquid separation equipment for sodium bicarbonate crystals and mother liquor.
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 filter centrifuge: continuous feed/wash/dewater; 0.1–10 mm (0.3–5 mm) + fibrous/sedimentary solids. For dilute/fine NaHCO₃, LWLZ pre-thickens then filters.
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 Bicarbonate (Baking Soda) 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 |
