<p>A process for obtaining metal parts from residues of waste incineration processes, comprising the following steps: a metal-detecting method, in particular an inductive measuring method, is used to separate the residues into metal-free and metal-containing slag and also pure metals, the metal-containing slag and free metals are introduced into the upper inlet of a shaft of a comminution apparatus, in which process rotor elements which are axially spaced apart and preferably consist of chains are driven in rotation about a vertical axis, wherein the material falls through the shaft from top to bottom, wherein mineral constituents of the slag are comminuted to form fine, granular material, free metals are freed from adhering slag, the metal parts remain substantially uncomminuted and the material which falls freely out of the shaft and emerges from a lower outlet of the comminution apparatus is subsequently sorted into metal parts and the remaining material.</p> |
