Zig-Zag Air Classifier for Plastic Recycling
Introducing our cutting-edge solution for sorting materials with unparalleled precision. This advanced system offers a systematic approach to separating lighter contaminants (like labels, dust, and film fines) from heavier plastic flakes, making it an invaluable asset in any high-purity recycling application.
Working Principle
The Zig-Zag Air Classifier operates on a simple yet effective principle, using air as the medium for separation. A column of rising air mixes with the material, offering a reliable way to sort materials based on their weight and aerodynamics.
- Lighter Contaminants Rise
Lighter objects like paper labels, film fines, and dust are blown upwards by the air column and exit through the top for collection.
- Heavier Plastics Descend
The heavier, clean plastic flakes are unaffected by the air and descend through the chamber, exiting through the bottom.

Frequently Asked Questions
The Zig-Zag Air Classifier is most commonly used as a final cleaning step in a PET or HDPE bottle recycling line. After the plastic flakes have been washed and dried, this machine removes the last traces of lightweight contaminants like paper/plastic label fragments and fines.
Yes, while it's ideal for plastic recycling, its principle of separating light from heavy materials makes it suitable for other industries, such as paper recycling (removing plastic films) or compost processing (removing light plastic contamination).
The machine has a simple design with minimal moving parts (primarily the blower and rotary valve), which results in very low maintenance requirements. Regular checks of the motors and ensuring the cyclone separator is clear are the main tasks.
