Metal part producing method, involves crushing mineral components of slag into fine, granular material, where material falling out freely from chamber and emerging from lower outlet becomes metal parts and remaining material are sorted

摘要

The method involves transmitting metal containing slag and free metals into an upper inlet of a chamber of a crushing device, in which rotor elements having chains are axially spaced at a distance and are rotatably driven around a vertical axis. A material falls from top to down through the chamber. Mineral components of the slag are crushed into a fine, granular material, and free metals are freed from an adhering slag, where the material falling out freely from the chamber and emerging from a lower outlet of the device becomes metal parts and the remaining material are sorted. A mixture of metal required for producing the metal part is separated into ferrous metal and non-ferrous metal. An independent claim is also included for a system for producing a metal part from residual products of waste incineration processes.
