Zig Zag Multi-Stage Air Separation
Energycle Zig Zag Air Classifier
Airflow-based separation equipment for removing labels, paper, film fragments, dust, and fines from plastic flakes, granules, and regrind.
Why It Fits Plastic Recycling Lines
Boost PET flake purity and protect downstream equipment by removing light contaminants before extrusion or washing.
Cleaner Flake Output
The zig-zag column creates repeated air crossflow so light contaminants separate from heavier plastic fractions efficiently, improving purity before washing, extrusion, or pelletizing.
Precise Removal
Separates paper, labels, and dust from heavier flakes with stable airflow control.
High Throughput
Suitable for bottle flakes and regrind in continuous-duty production lines without interrupting downstream flow.
Flexible for Different Feedstock
Air volume and suction can be tuned around flake size, bulk density, and contamination level for PET, rigid plastics, and film scrap.
Dust Control and Cyclone Collection
Closed-loop airflow and cyclone collection help reduce dust spread around the line while handling the light fraction independently for cleaner heavy-product output.
Low Maintenance
No internal rotating parts inside the separation chamber reduces wear and keeps maintenance simpler over long production runs.
How it works
How the Zig Zag Classifier Works
A multi-stage airflow column efficiently separates light contaminants from plastic flakes through gravity and suction.
Feed Entry
Plastic flakes or regrind enter the zig-zag chamber in an even flow.
Air Separation
Crossflow air lifts light contamination while heavier plastic drops through.
Capture
Dust and labels move with the air stream into cyclone collection.
Discharge
Heavier and cleaner plastic exits for the next processing stage.
Applications
Essential separation for high-purity plastic recycling lines.
PET Bottle Flakes
Removes residual labels, paper, and light film from washed flakes.
HDPE and PP Regrind
Removes dust and light foreign matter before extrusion or pelletizing.
Film and Flexible Scrap
Improves removal of low-density contamination from shredded film.

Frequently Asked Questions
It removes light impurities such as paper, labels, film fragments, dust, and fines from plastic flakes or regrind.
Typical applications include PET flakes, HDPE and PP regrind, mixed rigid plastics, film scrap, and WEEE plastics.
Yes. Depending on the configuration, the system can run with recirculated air to reduce dust and improve stability.
