Sink/Swim Tank

Sink/Swim Tank

Swim-sink tanks use the different specific weights of the various kinds of plastics to separate them. Typical applications are the separation of PET or PVC (both sink) from polyolefines, such as PE or PP (both of them swim). The light fraction is transported along the surface of the water by means of paddle drums to a discharge conveyor; the heavy fraction are extracted - depending on its amount - either by a pair of pneumatic valves at the bottom of the tank or by a scrape conveyor mounted below the tank.
