High-Capacity Pusher Centrifuge for Sodium Sulfate Dewatering

High-Capacity Pusher Centrifuge for Sodium Sulfate Dewatering is designed for continuous dewatering and mother liquor separation of sodium sulfate crystals in inorganic salt, chemical, evaporation crystallization, and resource recovery systems.

Sodium sulfate slurry usually comes from crystallization, evaporation concentration, salt recovery, or chemical production processes. The slurry contains sodium sulfate crystals, mother liquor, dissolved salts, fine particles, and residual process liquid.

A pusher centrifuge removes free liquid through centrifugal filtration and continuously discharges sodium sulfate crystal cake before drying, cooling, screening, or packaging.

• Sodium sulfate crystal dewatering
• Anhydrous sodium sulfate processing
• Glauber’s salt crystallization product separation
• Sodium sulfate slurry solid-liquid separation
• Mother liquor separation after crystallization
• Sodium sulfate wet cake discharge before drying
• Sodium sulfate cake washing and dewatering
• Evaporation crystallization product dewatering
• Inorganic salt recovery from wastewater or brine
• Continuous sodium sulfate production line integration

The actual separation result depends on crystal size, slurry concentration, mother liquor viscosity, screen opening, washing requirement, and operating parameters.

Sodium sulfate is often produced or recovered in bulk quantities. In large evaporation or crystallization systems, unstable or insufficient dewatering capacity can directly affect the whole production line.

If the centrifuge capacity is not properly matched, the plant may face:

• Bottleneck after crystallization
• Unstable feed to dryer or cooler
• High wet cake moisture
• Higher drying energy consumption
• Larger mother liquor carryover
• Product loss in filtrate
• Frequent screen blockage under high slurry load
• Inconsistent sodium sulfate product quality
• Reduced overall plant throughput

A high-capacity pusher centrifuge helps maintain continuous handling of sodium sulfate crystals from crystallizer discharge to dryer feeding.

Under suitable feed and operating conditions, the system can typically help achieve:

• High-throughput continuous dewatering for bulk sodium sulfate crystal production or recovery lines.
• 4–12% wet cake moisture for many well-formed sodium sulfate crystals
• 95–99.5% sodium sulfate crystal recovery when the screen opening is properly matched with particle size distribution.
• 50–85% reduction in free mother liquor carryover before drying compared with untreated wet slurry.
• 15–40% reduction in downstream dryer load
• More stable wet cake feeding to dryer, cooler, screening machine, or packaging section.
• 8–24 hours/day continuous operation

Final performance depends on sodium sulfate crystal size, particle shape, slurry concentration, mother liquor composition, viscosity, screen opening, centrifugal force, washing condition, and operating parameters.
