Effective sorting of plastics |
摘要 |
<p>In a centrifuging process for separation of plastic mixtures containing heavy materials, e.g., sand or metal residues, according to their density and using a separating fluid, some of the heavy materials are separated off in a hydrocyclone (15) and the remaining solids are separated from the rotating suspension in a following sorting centrifuge (20). Process equipment comprises a mixing vessel (10) for combining the solids (12) and separating fluid (11), connected via a pump (24) to a hydrocyclone (15) and a sorting centrifuge (20) whose feed (14) is connected to the overflow (16) from the hydrocyclone.</p> |
