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.

- Continuous calcium chloride production line integration
| Output Phase | Typical Composition | Main Purpose |
|---|---|---|
| Calcium Chloride Crystal Cake | Calcium chloride crystals or granular product | Recover crystal product and reduce surface liquid before drying |
| Mother Liquor / Brine | Concentrated calcium chloride solution, dissolved salts, process liquor | Separate free liquid from crystals for return, reuse, recovery, or treatment |
| Wash Liquor | Washing liquid after cake washing, if used | Reduce residual mother liquor or soluble impurities when required |
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.
Calcium chloride slurry enters the centrifuge through the feed pipe and is evenly distributed onto the rotating screen basket.
Under centrifugal force, concentrated mother liquor or brine passes through the screen openings and is collected as filtrate. Calcium chloride crystals are retained on the screen surface and form a filter cake.
The pusher mechanism moves the calcium chloride crystal cake forward step by step. During this movement, the cake continues to lose free liquid.
If product washing is required, wash liquid can be sprayed onto the crystal cake to reduce residual mother liquor or soluble impurities.
Finally, the dewatered calcium chloride crystal cake is discharged continuously from the basket end and sent to the dryer, cooler, screening machine, packaging section, or next process stage.

The centrifuge removes free brine from calcium chloride crystals, helping reduce wet cake moisture before drying.
Lower liquid carryover can reduce the amount of moisture that must be removed in the dryer.
Moisture-controlled cake discharge helps reduce sticky handling, unstable feeding, and caking risk before drying or packaging.
The machine supports continuous feeding, filtration, washing, dewatering, and discharge in calcium chloride production lines.
The pusher mechanism moves calcium chloride cake forward step by step, supporting continuous and stable solids discharge.
Cake washing nozzles can be added when residual mother liquor or soluble impurities need to be reduced.
The centrifuge can be connected with crystallizers, evaporators, dryers, coolers, screening machines, packaging systems, and brine recovery 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.
