perforated basket centrifuge
,bag lifting centrifuge
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.
- 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
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.
Peony provides not only centrifuge equipment but also complete separation support:
- Crystal characteristics analysis
- Particle size assessment
- Moisture target evaluation
- Washing requirement analysis
- Basket size selection
- Filter media selection
- Material configuration
- Explosion-proof design
- Installation guidance
- Commissioning service
- Spare parts support
- Operator training
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.
Peony provides not only centrifuge equipment but also complete sodium sulfate crystal separation solutions for inorganic salt plants, crystallization systems, evaporation projects, and salt recovery applications.
