Polymer - Air Classifier Brochure

Plastic regrind can be effectively cleaned by air classification. In the unique Polymer Recovery Systems air classification system, plastic flake, dominated by gravitational force, falls against a vertical air stream into a box filling station. Lighter materials, such as paper and fines, are carried with the air because of the influence of drag force. Cut point is controlled by a slide gate, which adjusts the vertical air velocity.Feed stock typically enters the system from a pneumatic conveying system via a pneumatic receiver. It then gravity-flows into the vertical air column through a rotary air lock. If desired, the system can be fed mechanically with a belt or screw conveyor.
