The Scraper Bottom Discharge Centrifuge is designed for dense, high-solids crystalline slurry that requires controlled feeding, stable cake formation, centrifugal dewatering, and automatic bottom discharge.
It is particularly suitable when the crystal-to-liquor ratio is high, slurry concentration fluctuates between batches, or upstream crystallization produces intermittent peak loads that require controlled basket filling and reliable cake discharge.
For high-solids slurry, the main challenge is not only liquid removal. The equipment must also handle dense feeding, maintain an even cake layer, avoid basket overload, control cake thickness, and discharge the dewatered crystals reliably. The scraper bottom discharge design is well suited for these requirements.
| Process Condition | Separation Impact | Peony Solution Focus |
|---|---|---|
| High crystal concentration | Thick cake can slow filtrate flow | Controlled feeding and batch loading |
| Fine crystals | Higher liquid retention and product loss risk | Filter medium selection and cake-depth control |
| Hot slurry discharge | Changes viscosity and crystallization behavior | Feed-temperature review and material selection |
| High mother liquor viscosity | Reduces drainage rate | Spin-drying cycle and cake-thickness optimization |
| Impurity accumulation in liquor | Can affect crystal quality | Mother liquor recycle and purge design |
| Crystal breakage | Can increase fines and reduce filtration performance | Controlled feeding and scraper adjustment |
| Washing requirement | Can improve purity but cause product loss | Wash-liquid selection and low-loss washing sequence |
| Continuous crystallizer output | Does not directly match batch centrifuge cycles | Agitated slurry buffer and PLC coordination |
Peony provides the crystal dewatering section between the evaporative crystallizer and downstream drying or screening system.
Evaporative Crystallizer → Agitated Slurry Buffer Tank → Controlled Feed → Scraper Bottom Discharge Centrifuge → Mother Liquor Recycle / Purge → Optional Cake Washing → Dryer / Screen / Storage
Peony can provide:
The final solution is selected according to crystal size, slurry solids concentration, mother liquor properties, target cake moisture, and downstream handling requirements.
Crystallizer slurry is transferred from the slurry buffer tank into the rotating basket through a controlled feed system.
Concentrated mother liquor passes through the filter medium and leaves through the filtrate outlet.
Crystals remain inside the basket and form a layer on the inner basket surface.
As feeding continues, the retained crystals gradually form a stable filter cake.
Compatible wash liquid can be applied to reduce residual mother liquor, soluble impurities, or unwanted salts retained between crystals.
The basket continues rotating at high speed to remove free liquid from the crystal cake before discharge.
After the programmed cycle is complete, the scraper removes the dewatered cake from the basket wall and discharges it automatically through the bottom outlet.

The centrifuge creates a controlled transition between upstream crystallization and downstream drying or finishing. It removes mother liquor before crystals enter the dryer, reducing liquid carryover and improving handling.
The scraper removes the dewatered cake automatically. This reduces manual handling and supports repeatable batch operation in crystallizer-based production lines.
The filtrate can be returned to the crystallizer, evaporation section, recycle tank, or controlled purge stream according to the process design.
The cake can be washed before final spin drying when lower mother liquor carryover or improved product purity is required.
The machine is suitable for concentrated slurry from evaporative crystallizers where crystals can form a stable, permeable, and removable cake.
To recommend a suitable evaporative crystallizer slurry dewatering solution, please provide:
It can receive slurry from an evaporative crystallizer, but an agitated slurry buffer tank is normally recommended between the crystallizer and centrifuge. This helps stabilize feed concentration and match continuous crystallizer output with automatic batch separation.
Yes, provided the slurry remains pumpable and the crystals can form a stable, permeable cake inside the basket.
Yes. The filtrate can be recycled to the crystallizer, evaporator, mother liquor tank, or a controlled purge stream, depending on the process balance and impurity accumulation level.
Yes. Optional cake washing can reduce residual mother liquor and improve product cleanliness. The wash liquid and wash volume should be selected carefully to control product loss.
The centrifuge itself is an automatic batch machine. It is suitable for continuous or semi-continuous crystallization systems when a slurry buffer tank is used to match the two operating modes.
Peony welcomes distributor and agent cooperation with evaporation and crystallization contractors, salt producers, chemical manufacturers, MEE and TVR system suppliers, wastewater salt recovery projects, and industrial separation partners.
Send us your crystallizer type, crystal product, slurry solids concentration, particle size, mother liquor composition, feed temperature, required capacity, target cake moisture, washing requirement, and downstream handling layout. Our engineering team will help recommend a suitable Scraper Bottom Discharge Centrifuge solution for evaporative crystallizer slurry dewatering.
