ABSTRACT:
An apparatus is disclosed for separating polyethylene film from paper fibre. The polyethylene film contaminated with paper fibres is subjected to treatment that converts the paper fibres into substantially uniform balls which are separated by gravity by being entrained in a stream of air with the polyethylene film pieces and impacted against a plurality of impact surfaces and the relatively light polyethylene film being separated from the relatively heavier damp paper fibres by means of a plurality of baffle separators relying upon gravity separation of the heavier components. Provision is made to remove the damp paper fibre balls and recover the polyethylene film from the apparatus.
