Abstract

Das Verfahren zur Aufbereitung von Flugasche aus Verbrennungs anlagen ist dadurch gekennzeichnet, daß die Aschen je nach Herkunft und Zusammensetzung nacheinander in beliebiger Reihenfolge mindestens zwei der folgenden Trennverfahren unterworfen werden:
Flotation (6), Auftrennung im Hydrozyklon (7), nasse und/oder trockene Magnetabscheidung (5), Windsichtung (11), nasse und/oder trockene Siebung (, Sink-Schwimm-Scheidung, worauf gewünschtenfalls eine Entwässerung, Eindickung und Trocknung (9) erfolgt, wobei die trockene Magnetabscheidung, trockene Siebung und Windsichtung entweder vor dem nassen Trennverfahren oder nach der Trocknung erfolgen, worauf gewünschtenfalls eine Mahlung erfolgt. Die Vorrichtung zur Durchführung des Verfahrens besteht aus der in beliebiger Reihenfolge nacheinander schaltbaren Kombination von verschiedenen Trennvorrichtungen. The process for processing fly ash from incineration plants is characterized in that the ashes are subjected to at least two of the following separation processes in succession in any order, depending on their origin and composition:
Flotation (6), separation in the hydrocyclone (7), wet and / or dry magnetic separation (5), wind sifting (11), wet and / or dry sieving (, sink-swim separation, followed by drainage, thickening and drying if desired ( 9) is carried out, the dry magnetic separation, dry sieving and air separation either before the wet separation process or after the drying, whereupon, if desired, grinding is carried out.The device for carrying out the process consists of the combination of different separation devices which can be switched in any order.
