The Scraper Bottom Discharge Centrifuge is designed for batch solid-liquid separation and dewatering of chloride crystals after crystallization.
It is suitable for chloride salt production, chemical crystallization, salt recovery, and evaporation systems where automatic cake discharge, stable moisture control, and corrosion-resistant configuration are required.
For chloride crystal separation, Peony provides not only centrifuge equipment, but also process evaluation, model selection, filter media matching, anti-corrosion material selection, washing design, automation support, and long-term technical service.
Chloride crystal separation is commonly used in inorganic salt, chemical, fertilizer, brine treatment, and salt recovery processes. The separation result directly affects final moisture, crystal purity, drying load, mother liquor recovery, and downstream production stability.
This solution is suitable for:
| Chloride Crystal Type | Application Purpose |
|---|---|
| Sodium chloride crystals | Salt crystal separation and dewatering |
| Potassium chloride crystals | Fertilizer-grade crystal recovery |
| Calcium chloride crystals | Mother liquor removal and moisture reduction |
| Magnesium chloride crystals | Crystal separation after crystallization |
| Ammonium chloride crystals | Cake washing and dewatering |
| Mixed chloride crystals | Salt recovery and solid-liquid separation |
| Brine crystallization salts | Chloride crystal recovery |
| ZLD chloride salts | Waste salt separation and dewatering |
The scraper bottom discharge structure is especially suitable for chloride crystals with medium to large batch capacity, high solids content, corrosive mother liquor, and frequent industrial production cycles.
| Challenge | Possible Cause | Solution Focus |
|---|---|---|
| High cake moisture | Fine crystals or short dewatering time | Basket speed and cycle optimization |
| Corrosion risk | Chloride-rich mother liquor | SS316L, duplex steel, titanium, or lining options |
| Difficult discharge | Compact or sticky crystal cake | Automatic scraper bottom discharge |
| Salt loss in filtrate | Unsuitable filter media | Filter cloth or screen matching |
| Poor washing result | Uneven cake washing | Washing pipe and cake thickness control |
| Scaling and blockage | High salt concentration | Cleaning access and process control |
| High labor intensity | Manual unloading | Automatic scraper discharge |
| Unstable batch quality | Variable crystal size or feed concentration | Process evaluation before model selection |
| System Part | Function |
|---|---|
| Slurry feeding system | Transfers chloride crystal slurry into the centrifuge |
| Scraper bottom discharge centrifuge | Separates mother liquor and dewaters crystal cake |
| Filter media system | Retains crystals and improves filtrate clarity |
| Cake washing system | Removes residual mother liquor and improves purity |
| Mother liquor outlet | Collects filtrate for recovery or treatment |
| Automatic scraper discharge | Discharges crystal cake from the bottom outlet |
| PLC control system | Controls feeding, filtration, washing, spinning, and discharge |
| Anti-corrosion configuration | Protects equipment in chloride-rich environments |
| Downstream connection | Dryer, conveyor, silo, packaging, or further processing |
This allows the centrifuge to work as part of a complete chloride crystal production or salt recovery line.
The typical process is:
Slurry Feeding → Basket Filtration → Crystal Cake Formation → Optional Cake Washing → Final Dewatering → Scraper Bottom Discharge → Chloride Crystal Collection → Mother Liquor Recovery → Cleaning for Next Batch
During operation, chloride crystal slurry enters the rotating basket. Under centrifugal force, the mother liquor passes through the filter media while chloride crystals are retained on the basket wall. After optional washing and final dewatering, the scraper automatically removes the cake and discharges it through the bottom outlet.
This process reduces manual operation, improves discharge efficiency, and supports stable batch production.

Chloride systems can be highly corrosive, especially at high concentration or elevated temperature. Contact materials can be selected according to process conditions, including SS316L, duplex stainless steel, titanium, or lined structures.
The scraper removes the crystal cake automatically from the basket wall, reducing manual unloading and improving batch efficiency.
The centrifuge is suitable for chloride crystal slurry with high solids concentration and heavier crystal cake formation.
A washing system can be added to reduce residual mother liquor and improve crystal purity.
Adjustable spinning time, cake thickness, and operating cycle help achieve consistent final cake moisture.
Bottom discharge can be connected with dryers, conveyors, collection bins, silos, or packaging systems.
To recommend a suitable centrifuge solution, please provide:
Yes. It is suitable for sodium chloride, potassium chloride, calcium chloride, magnesium chloride, ammonium chloride, and mixed chloride crystal separation after crystallization.
Chloride-rich mother liquor may cause corrosion, especially under high temperature or acidic conditions. Material selection should be based on chloride concentration, pH, temperature, and process environment.
Yes. A cake washing system can be added to remove residual mother liquor and improve crystal purity.
It uses automatic scraper bottom discharge. The scraper removes the crystal cake from the basket wall and discharges it through the bottom outlet.
Yes. It can be used for chloride salt recovery and dewatering in evaporation, crystallization, and ZLD systems.
Peony welcomes distributors, agents, EPC contractors, chemical process integrators, and industrial solution providers involved in chloride salt production, inorganic salt processing, brine treatment, evaporation crystallization, and ZLD salt recovery projects.
We support partners with centrifuge selection, process evaluation, anti-corrosion configuration, filter media matching, cake washing design, technical documents, spare parts supply, marketing materials, and global after-sales service.
Send us your customer’s chloride crystal type, capacity, particle size, mother liquor composition, corrosion condition, and target moisture. Our engineering team will recommend a suitable Scraper Bottom Discharge Centrifuge solution and provide long-term technical support for your market.
