Abstract
Method to produce a polymeric product starting from a primary heterogeneous mixture comprising polymeric material, comprising fragmentation into desired sizing, mechanical primary selection of the fragmented material and plastification, obtaining a densified material which is then subjected to quenching.
Claims15
Method to produce a polymeric product, said method comprising:
- fragmentation into desired sizing of a primary heterogeneous mixture comprising polymeric material, obtaining a fragmented material of the desired sizing;
- mechanical primary selection, waterless, of said fragmented material to remove metallic material, non-polyolefin polymers and non-polymeric foreign fraction;
- subjecting said fragmented material to plastification, obtaining a densified material;
- subjecting said densified material to quenching at least by air cooling carried out with pneumatic transport, thus obtaining a densified and cooled material which constitutes said polymeric product.
