Scraper Bottom Discharge Centrifuge for Sodium Sulfate Dewatering
Description
The Scraper Bottom Discharge Centrifuge is specially designed for the solid-liquid separation of sodium sulfate crystals after crystallization. It is widely used in chemical plants, inorganic salt production, mining chemicals, and wastewater salt recovery systems.
The centrifuge automatically completes feeding, filtration, cake washing, dewatering, scraping, and discharge within one batch cycle. It is particularly suitable for sodium sulfate crystals with high solids content, large crystal size, and high production capacity requirements.
Compared with manual discharge centrifuges, the scraper discharge design significantly reduces labor intensity and improves production efficiency while maintaining stable crystal quality.
Typical Sodium Sulfate Applications
- Natural sodium sulfate production
- Chemical-grade sodium sulfate manufacturing
- Detergent-grade sodium sulfate processing
- Glauber's salt crystal dewatering
- Sodium sulfate recovery from wastewater
- Sodium sulfate crystallization systems
- Inorganic salt production lines
- Salt lake mineral processing
Why Choose Scraper Bottom Discharge Centrifuge for Sodium Sulfate Dewatering
Pharmaceutical intermediate production often faces several separation challenges:
- Strict GMP and hygiene requirements
- High product value and low material loss tolerance
- Fragile crystals requiring gentle handling
- Frequent product changeovers
- Requirement for complete batch recovery
- Toxic or solvent-containing products requiring enclosed operation
The Bag Lifting Centrifuge addresses these challenges through a fully enclosed filtration system and convenient bag lifting discharge design.

How the Scraper Bottom Discharge Centrifuge Works in Sodium Sulfate Dewatering
The sodium sulfate slurry is fed into the rotating basket lined with filter media.
Under centrifugal force:
- Mother liquor passes through the filter medium.
- Sodium sulfate crystals are retained inside the basket.
- Optional washing liquid is sprayed onto the cake.
- High-speed spinning removes residual moisture.
- The scraper automatically discharges the crystal cake through the bottom outlet.
The complete cycle is automatically controlled through PLC operation.

FAQ
Why is a scraper centrifuge suitable for sodium sulfate?
Sodium sulfate crystals are generally coarse and easy to filter. The scraper discharge system can efficiently remove large crystal cakes while reducing manual labor.
Can the centrifuge perform cake washing?
Yes. A washing system can be integrated to improve sodium sulfate purity.
What moisture content can be achieved?
Final moisture typically ranges from 2% to 8%, depending on crystal size and operating conditions.
Can it handle corrosive salt solutions?
Yes. SS316L, Duplex Stainless Steel, Titanium, and other corrosion-resistant materials are available.
Is explosion-proof design available?
Yes. ATEX-compliant and explosion-proof configurations can be provided when required.
