<p>Basic and recycling basic thermoplastics are recovered by utilising a centrifuge to separate the materials into segments. In the centrifuge the materials are fused into a granular state by a stream of hot gas; they are then completely fused on rotating segments, disintegrated over the surface of the segments and formed into a foam with the gas, also being stretched by a gas or liq. medium. ADVANTAGE - The centrifuge recovers unsorted thermoplastic materials for further renewed use as flock, fibres or fibres which can be beaten and made into paper.</p> |
