Sink-Schwimm-Tank-System für PET-Recycling
The sink-float separation tank is a core purification stage in PET bottle recycling, designed to remove floating PP and PE contaminants from heavier PET flakes through density-based separation in water.
It improves final flake purity, stabilizes downstream hot washing and drying, and supports higher-value rPET output.
- Separates PET from PP, PE, and label residues by density.
- Provides extra soaking and washing time during purification.
- Available in custom lengths and widths for different throughput targets.

Arbeitsprinzip der PET-Flocken-Reinigung
Water acts as the separation medium: heavier PET sinks while lighter caps and label fragments float to the surface for removal.
PET-Flocken Spüle
Because PET is denser than water, the valuable flakes settle to the bottom and are collected by the discharge conveyor.
Verunreinigungen schwimmen
PP and PE bottle caps, label pieces, and other light contaminants remain on the surface for removal.
Hauptvorteile
A critical separation stage for improving rPET flake quality before drying, storage, or pelletizing.
Hohe PET-Reinheit
Removes a significant amount of PP and PE contamination from bottle caps and label fractions.
Doppelfunktionales Verfahren
The system separates by density while also providing an additional wet cleaning stage.
Optimierte Einweichzeit
Tank lengths from 4 to 6 meters allow more complete settling and more stable separation.
Langlebige Konstruktion
Type 304 stainless steel is used on key internal sections for corrosion resistance and long service life.

Häufig gestellte Fragen
Welches sind die Hauptverunreinigungen, die dieser Tank aus PET-Flocken entfernt?
The primary contaminants are plastic bottle caps and label fragments made from PP or PE. These float while the heavier PET flakes sink.
Warum ist ein längerer Tank besser?
A longer tank provides a longer residence time in water, allowing PET flakes to settle more completely and improving separation efficiency.
Kann dieser Tank für meine Einrichtung angepasst werden?
Yes. Tank dimensions and motor configurations can be adjusted to match throughput requirements and facility layout.
