The scraper bottom discharge centrifuge is designed for batch solid-liquid separation and dewatering of inorganic salt crystals.
It is suitable for inorganic salt production lines that require efficient crystal recovery, automatic cake discharge, stable moisture control, continuous batch operation, and reduced manual handling.
For inorganic salt separation projects, Peony provides complete centrifuge solutions including process evaluation, equipment selection, filter media matching, crystal washing design, anti-corrosion configuration, automation integration, and production support.
Inorganic salt production often involves crystallization, washing, purification, and dewatering processes. Efficient solid-liquid separation directly affects product quality, drying efficiency, salt recovery rate, energy consumption, and plant productivity.
This solution is suitable for:
| Material Type | Application Purpose |
|---|---|
| Sodium Sulfate | Crystal dewatering and mother liquor separation |
| Sodium Chloride | Salt crystal recovery |
| Potassium Sulfate | Crystal washing and dewatering |
| Potassium Chloride | Product purification and moisture reduction |
| Sodium Carbonate | Solid-liquid separation after crystallization |
| Ammonium Sulfate | Crystal recovery before drying |
| Various Inorganic Salts | Batch crystal separation and dewatering |
The scraper bottom discharge structure is particularly suitable for medium and large-capacity inorganic salt production where frequent unloading, stable operation, and reduced labor requirements are important.
In inorganic salt production, common separation issues include:
| Challenge | Possible Cause | Solution Focus |
|---|---|---|
| High residual moisture | Fine crystal size or insufficient dewatering | Basket speed and cycle optimization |
| Crystal breakage | Excessive centrifugal force | Process parameter optimization |
| Difficult cake discharge | Compact crystal cake formation | Scraper discharge mechanism |
| Salt loss in filtrate | Improper filter media selection | Filter cloth optimization |
| Corrosion problems | Chloride-rich mother liquor | SS316L, duplex steel, or special alloys |
| High labor intensity | Manual unloading requirements | Automatic scraper discharge |
| Product contamination | Inadequate cleaning between batches | Easy-cleaning design |
| Inconsistent product quality | Variable crystal size distribution | Stable operating parameters |
| System Part | Function |
|---|---|
| Slurry Feeding System | Transfers crystal slurry into the centrifuge |
| Scraper Bottom Discharge Centrifuge | Separates crystals from mother liquor |
| Filter Cloth System | Retains crystals and clarifies filtrate |
| Cake Washing System | Improves product purity |
| Mother Liquor Collection | Recovery or recirculation of filtrate |
| Automatic Scraper Discharge | Removes crystal cake efficiently |
| Control System | Manages operating cycles |
| Anti-Corrosion Configuration | Protects equipment from salt corrosion |
| Downstream Connection | Dryer, conveyor, silo, or packaging line |
This allows the centrifuge to become an integrated part of a complete inorganic salt processing line.
The typical process is:
Slurry Feeding → Basket Filtration → Crystal Cake Formation → Optional Cake Washing → Final Dewatering → Scraper Discharge → Bottom Product Collection → Mother Liquor Recovery → Cleaning for Next Batch
During operation, the inorganic salt slurry enters the rotating basket. Under centrifugal force, the liquid phase passes through the filter media while crystals are retained on the basket wall. After washing and dewatering, the scraper mechanism automatically removes the crystal cake and discharges it through the bottom outlet.
This process improves unloading efficiency, reduces labor requirements, and supports stable batch production.

The scraper mechanism removes the crystal cake automatically, reducing manual labor and improving production efficiency.
Compared with top discharge centrifuges, scraper bottom discharge centrifuges are better suited for larger production capacities and more frequent operating cycles.
Proper filtration and discharge design help maximize crystal recovery and minimize product loss.
Automatic cake removal significantly reduces operator involvement during discharge.
Automated discharge improves batch repeatability and production stability.
Material selection can be optimized for chloride-containing salts and other corrosive process conditions.
The centrifuge can be customized according to the process:
| Item | Available Configuration |
|---|---|
| Contact Material | SS304, SS316L, Duplex Stainless Steel |
| Surface Treatment | Anti-corrosion polishing |
| Filter Media | Customized according to crystal size |
| Washing System | Optional crystal cake washing |
| Motor | Standard or explosion-proof |
| Control System | Standard or PLC automation |
| Scraper Mechanism | Pneumatic or hydraulic control |
| Sealing Design | Open, semi-sealed, or enclosed |
| Cleaning Design | Easy maintenance configuration |
| Downstream Integration | Conveyor, dryer, silo, packaging line |
| Downstream connection | Dryer, conveyor, collection bin, or packaging line |
