Moisture-Control Pusher Centrifuge for Calcium Chloride Dewatering

Moisture-Control Pusher Centrifuge for Calcium Chloride Crystal Dewatering is designed for continuous dewatering and brine separation of calcium chloride crystals in inorganic chemical and salt processing lines.

Calcium chloride is highly hygroscopic. After crystallization or brine concentration, calcium chloride crystals may carry concentrated mother liquor, residual brine, and surface moisture. If this liquid is not removed effectively, downstream drying, cooling, screening, storage, and packaging may become unstable.

A moisture-control pusher centrifuge removes free liquid through centrifugal filtration and continuously discharges calcium chloride crystal cake before drying or further handling.

• Calcium chloride crystal dewatering
• Calcium chloride brine separation
• Calcium chloride slurry solid-liquid separation
• Mother liquor separation after crystallization
• Calcium chloride wet cake discharge before drying
• Hygroscopic crystal moisture control
• Inorganic salt crystal dewatering
• Evaporation crystallization product separation
• Calcium chloride recovery from brine or process liquor
• Continuous calcium chloride production line integration

The actual separation result depends on calcium chloride crystal form, crystal size, slurry concentration, brine concentration, viscosity, temperature, screen opening, and operating parameters.

Calcium chloride is more moisture-sensitive than many common inorganic salts. If excess mother liquor remains on the crystal surface, the plant may face:

• Higher dryer energy consumption
• Sticky or wet crystal cake before drying
• Product caking during storage or packaging
• Unstable feeding to dryer, cooler, or screening machine
• Higher risk of moisture reabsorption
• More dust or agglomeration problems after drying
• Lower product flowability
• Product loss through unsuitable screen opening
• Frequent cleaning caused by crystal build-up

A moisture-control pusher centrifuge helps remove free brine from calcium chloride crystals before drying, making downstream handling more stable.

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.

It is used for continuous dewatering and brine separation of calcium chloride crystals before drying or further processing.

Calcium chloride is highly hygroscopic. Excess surface liquid can cause sticky handling, unstable drying, caking, and packaging problems.

Yes. By removing free brine before drying, the centrifuge can reduce the liquid load entering the dryer.

Yes. Cake washing nozzles can be added if the process requires reduced residual mother liquor or soluble impurities.

Final moisture depends on crystal size, cake permeability, slurry concentration, brine viscosity, temperature, screen opening, centrifugal force, and operating settings.
