Heavy-Duty Pusher Centrifuge for Mineral Salt Dewatering

Heavy-Duty Pusher Centrifuge for Mineral Salt Dewatering is designed for continuous solid-liquidseparation of mineral salt crystals, salt lake crystallization products, brine-derived salts, andinorganic salt mixtures.

In mineral salt recovery, salt lake brine processing, mining brine treatment, and evaporationcrystallization systems, the discharged slurry may contain mineral salt crystals, mother liquor, fineparticles, insoluble impurities, and mixed inorganic salts.

A heavy-duty pusher centrifuge removesfree liquid through centrifugal filtration and continuously discharges dewatered mineral salt cakebefore drying, cooling, screening, or packaging.

• Mineral salt crystal dewatering
• Salt lake brine crystallization product separation
• Mining brine salt recovery
• Mixed inorganic salt dewatering
• Mother liquor separation after crystallization
• Mineral salt wet cake discharge before drying
• Brine-derived salt crystal separation
• Evaporation crystallization product dewatering
• Salt recovery from high-salinity wastewater
• Continuous mineral salt processing line integration

The actual separation result depends on salt composition, crystal size, slurry concentration, brine viscosity, impurity content, screen opening, and operating parameters.

Mineral salt slurry is often more complex than single chemical crystal slurry. It may contain mixed salts, abrasive particles, fine impurities, and high-concentration brine. In salt lake, mining, or resource recovery projects, the centrifuge usually needs to operate continuously under variable feed conditions.

If the machine is not designed for heavy-duty operation, the plant may face:

• Unstable cake discharge
• Higher wet cake moisture
• Faster screen segment wear
• More product loss through unsuitable screen openings
• Blockage caused by fine mineral particles
• Higher load on downstream dryers
• Frequent cleaning and maintenance
• Reduced overall crystallization line capacity
• Poor adaptability to changing brine composition

A heavy-duty pusher centrifuge helps maintain stable filtration, continuous cake discharge, and long-term operation in mineral salt dewatering systems.

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

• 4–12% wet cake moisture for many well-formed calcium chloride crystals
• 50–85% reduction in free brine carryover before drying compared with untreated wet slurry.
• 95–99.5% calcium chloride crystal recovery when the screen opening is properly matched with particle size distribution.
• 15–40% reduction in downstream dryer load
• More stable wet cake
• Reduced risk of sticky cake handling, uneven drying, and caking caused by excessive liquid carryover.
• 8–24 hours/day continuous operation

Final performance depends on calcium chloride crystal size, particle shape, slurry concentration, brine concentration, viscosity, temperature, screen opening, centrifugal force, washing condition, and operating parameters.
