About Used Density Separators & Air Classifiers
Density separators and air classifiers sort recycled material by density and aerodynamic properties. Float-sink tanks separate polymers by specific gravity (for example PP/PE from PET/PVC), while air classifiers (zig-zag separators and air tables) remove light fractions like film, dust, and fluff from heavier rigid pieces. These systems are critical for producing clean, single-polymer recycling streams.
When buying a used density separator or air classifier, evaluate throughput, the density cut points required, and integration with upstream shredding/granulating and downstream washing. Meadoworks sources separation equipment for recyclers. Contact us at 800-323-0307.

Frequently Asked Questions
How do density separators work in recycling?
Density separators sort material by specific gravity — float-sink tanks separate polymers that float (PP/PE) from those that sink (PET/PVC), while air classifiers use airflow to lift light fractions like film and dust away from heavier rigid pieces.
