The Critical Separation Stage In Sodium Metabisulfite Processing
After reaction/absorption and crystallization, sodium metabisulfite forms a crystal-containing slurry that must undergo solid-liquid separation to recover crystals before downstream drying. The centrifuge continuously separates crystals from mother liquor, reducing mother-liquor entrainment and delivering the right feed condition for drying.
Why Separation
Performance Matters？
Centrifuge performance directly drives sodium metabisulfite production efficiency.
High Mother-liquor Entrainment
High crystal moisture, higher drying energy consumption.
Fine Crystals / Low-concentration Slurries
Fine powder lost with the liquid phase lowers product recovery.
Chloride Corrosion
High-Cl mother liquor causes pitting in 316L, shortening equipment life and contaminating product purity.
Continuous Production Downtime
Screen blockage, bearing/seal failure, and wear damage all drive up maintenance costs.

How to Choose the Right Centrifuge for Your Sodium Metabisulfite Process?
| Comparison Criteria | LWL | LWLZ |
|---|---|---|
| Feed Concentration | Conventional Solids-bearing Slurry | Low Solids, Highly Fluctuating Concentration |
| Separation Method | Screen Filtration + Screw Deliquoring | Sedimentation Thickening + Screen Filtration |
| Fine-particle Adaptability | Depends on Proper Screen Matching | Enhanced fine-particle capture in the sedimentation zone |
| Crystal Integrity | Relatively Good | Slight breakage possible in the sedimentation zone |
| Typical Applications | Continuous Crystalline Salt Separation | Dilute slurry with fine crystals, requiring pre-thickening |
