<p>The invention refers to a procedure and an installation for the pure, according to sort, processing of recoverable material refuse, with a selection of heavy disruptive materials, with a crushing process for the remaining raw refuse, with segregating processes for recoverable materials from the crushed raw refuse up to a mixture of plastic chips and with separating processes for the extraction of pure, according to sort, plastics.The following procedural steps are proposed with the object of reducing the procedural steps, the reduction of the expenditure of energy with simultaneous enhancement of the sorting quality:a) soaking of the singled raw refuse in a fluid with the object of dissolving, parting and peeling of soluble components,b) selecting of heavy disruptive materials in a horizontal fluid flow dependent upon the sinking speed,c) conveying of the moist raw refuse liberated from hearty disruptive materials to the crushing installation,d) crushing of the moist raw refuse to a chip size of less than 55 mm with simultaneous drying by the crushing heat,e) separation of recoverable materials up to the mixture of different types of plastic,in at least one process step for the separation of minimum-size and light substances, especially fibre substances, silicon compounds and organic contaminations, and/orin at least one procedural step for the segregation of metals, andf) separation of the mixture of different types of plastic according to the float-and-sink method dependent upon the density.</p> |
