Abstract
Apparatus for separating snakeskins and fines from pellets in a collection of polymeric material wherein a first nozzle impinges the collection of polymeric material in a stream of air on a moving screen having a mesh size such that the screen will allow the air and fines to pass but will retain the pellets and snakeskins, the air stream carrying the fines through the screen into a closed compartment. A second nozzle is positioned to allow air from the closed compartment to move upwardly through the screen at a different location from the first nozzle to lift and remove snakeskins from the screen.
