Abstract
In a method for sorting shredder residues of metal-containing wastes, e.g., vehicle bodies, the shredder residues are separated into a shredder light fraction and a non-ferromagnetic fraction (shredder heavy fraction). A system is arranged for sorting shredder residues of metal-containing wastes, e.g., vehicle bodies. At least parts of the primary material streams produced during the sorting of the shredder light fraction and the shredder heavy fraction in preliminary processes are fed to a common, main process for final processing, at least a ferromagnetic fraction, a fraction containing non-ferromagnetic metals, a granulate fraction, a fiber fraction, and a sand fraction being produced as end products.
Claims18
A method for treating shredder residues of metal-containing waste, comprising:
- separating the shredder residues into a shredder light fraction and a non-ferromagnetic fraction;
- separating each of the shredder light fraction and the non-ferromagnetic fraction into additional material streams in separate preliminary processes;
- feeding at least a part of one of the material streams of a first one of the preliminary processes and at least a part of the material stream of a second one of the preliminary processes to a joint main process for further processing;
- and
- producing from the main process an iron-containing fraction, a fraction containing nonferrous metals, a granulate fraction, a fiber fraction and a sand fraction.
A system for sorting shredder residues of metal-containing waste, the shredder residues including a light shredder fraction and a non-ferromagnetic fraction, comprising:
- an arrangement configured to supply to a joint, main process for final processing at least parts of primary material streams formed during sorting of the light shredder fraction and the non-ferromagnetic fraction in preliminary processes, to produce at least a ferromagnetic fraction, a fraction containing nonferrous metals, a granulate fraction, a lint fraction and a sand fraction as end products.
