A zigzag air classifier for PET flakes separates material by how it responds to an upward air stream. Light label fragments and film rise with the air. The heavier flakes drop to a lower outlet for collection.
How the air classifier removes light labels
The airflow can be adjusted for the feedstock. The demonstration shows a dry separation step used to remove light contaminants that may remain in the flake stream after washing and drying.
