The Top Discharge Centrifuge is designed for batch washing, solid-liquid separation, and dewatering of filterable polymer beads after polymerization, post-treatment, purification, classification, or recovery.
Polymer bead slurry may contain spherical polymer particles, water or solvent, residual monomer, dispersants, salts, reaction auxiliaries, fine-particle fractions, and soluble impurities. The dewatering stage must remove free liquid efficiently while retaining the beads, limiting unnecessary bead breakage, and supporting clean transfer to downstream drying, screening, storage, or packaging.
This configuration is suitable for batch polymer bead processes where particles are filterable, reasonably free-flowing, and able to form a stable bed inside the basket.
Peony provides the batch separation section between upstream polymerization, washing, slurry storage, or purification equipment and downstream drying, screening, storage, or packaging systems.
Polymerization Reactor / Washing Tank → Slurry Holding Tank → Controlled Feed → Top Discharge Centrifuge → Filtrate Collection / Recycle → Optional Bead Washing → Spin Dewatering → Top Opening → Polymer Bead Discharge → Dryer / Screen / Storage / Packaging
Peony can provide:
Polymer bead slurry enters the rotating basket through a controlled feed system. The feed rate is adjusted to support even loading and avoid excessive bead movement.
Water, solvent, mother liquor, or process liquid passes through the screen or filter medium and basket perforations before leaving through the filtrate outlet.
The polymer beads remain inside the basket while the liquid phase is discharged.
As feeding continues, the retained beads gradually form a stable and permeable bed on the inner basket wall.
Wash liquid can be introduced to reduce residual monomer, salts, dispersants, solvent, reaction liquor, or soluble impurities retained between the polymer beads.
The basket continues rotating to reduce free liquid retained in the polymer bead bed.
After the programmed batch cycle is complete, the centrifuge stops and the top cover is opened.
The dewatered polymer beads are discharged manually through the top opening and transferred to a collection bin, dryer, screen, classifier, storage bin, or packaging process.

The basket filtration system retains polymer beads while allowing water, solvent, or process liquor to pass through the filter medium.
Filtration followed by spin dewatering helps reduce liquid carryover before the polymer beads enter drying, screening, storage, or packaging.
A controlled wash step can reduce residual monomer, salts, dispersants, reaction liquor, or soluble impurities before downstream handling.
Screen opening, mesh size, or filter media rating can be selected according to bead diameter, fines content, filtrate clarity requirements, and acceptable particle loss.
The batch process allows adjustment of feed quantity, wash time, spin-drying time, and discharge timing according to actual polymer bead condition.
| Suitable For | Typical Characteristics |
|---|---|
| Filterable polymer beads | Particles can form a stable and permeable bed |
| Suspension-polymerized beads | Require washing and liquid removal after production |
| Medium-to-coarse polymer particles | Suitable for screen or filter cloth retention |
| Water- or solvent-washed beads | Residual liquid needs removal before drying or storage |
| Batch production processes | Centrifuge cycle can match upstream production rhythm |
| Recoverable polymer media | Beads need transfer for reuse, screening, drying, or packaging |
Please provide:
Yes, provided the polymer beads are filterable and can form a stable, permeable bed inside the basket.
Yes. An optional in-basket washing system can be configured to reduce residual monomer, salts, dispersants, solvent, or process liquor before final spin dewatering.
This depends on bead hardness, particle size, feed method, washing conditions, basket loading, and discharge practice. Controlled feeding and suitable operating parameters help reduce unnecessary breakage.
Yes. Filtrate can be collected for recycle, recovery, further washing, solvent recovery, or wastewater treatment according to the process route.
Yes. Explosion-proof motors and electrical configuration can be provided where required by solvent properties, area classification, and plant safety standards.
