Process and apparatus for separating heterogeneous plastic material into homogeneous fractions. |
摘要 |
<p>A process for separating heterogeneous plastic material into homogeneous fractions, which comprises a) feeding the plastic material in a triturated form to a first water-containing separation tank (1) in order to separate the high specific weight products from the low specific weight products; b) recovering the mixture of high specific weight products from the bottom of said first separation tank and drying them in a first drier (2); c) treating the resulting mixture with a chemical agent capable of swelling/modifying at least part of the plastic materials; d) feeding the treated plastics material to a second separation tank (5), in which the non-swollen/non-modified plastic material precipitates while the remaining material, maintained on the surface, is discharged. <IMAGE></p> |
