  Verfahren zur Gewinnung zerkleinerter Schlacke aus Müllschlacken für die Herstellung von Kunststeinen. 



   Das Zerkleinern von Müllschlacken, welche sich aus der Verbrennung von Müll in den bekannten   () fen   ergeben, geschieht bisher durch Brechen der Schlacken in   Schlackenbrechern.   



  Diese so gewonnene gebrochene Schlacke wird zur Herstellung von Kunststeinen zu Bauzwecken verwandt. 



   Zu dem Brechen der Schlacke ist ein erheblicher Kraftaufwand notwendig ; ausserdem entsteht bei dem Brechen unangenehmer Staub. Die gebrochene Schlacke ist von sehr verschiedener Korngrösse und muss vor der Verwendung sortiert werden. Man hat nun das Brechen der Schlacken dadurch zu vermeiden versucht, dass man das Müll, wie z. B. in der deutschen Patentschrift Nr. 75322 beschrieben ist, in einem Flammenofen geschmolzen und dann die flüssige Schlacke granuliert hat. Dieses Verfahren hat sich als unwirtschaftlich erwiesen, weil es einen zu hohen Brennstoffzusatz verlangt. Es ist dann versucht worden, das Müll in Schachtofen zu schmelzen, jedoch ist auch dieses unvorteilhaft, da die mechanischen Eigenschaften des Mülls, nämlich das Zusammensinken desselben zu einer für die Verbrennungsluft undurchdringlichen Masse.

  Process for the extraction of crushed slag from waste slag for the production of artificial stones.



   The crushing of waste slag, which results from the incineration of waste in the well-known () fen, has so far been done by breaking the slag in slag breakers.



  The broken slag obtained in this way is used to manufacture artificial stones for building purposes.



   Considerable effort is required to break the slag; in addition, unpleasant dust is produced when breaking. The crushed slag has very different grain sizes and has to be sorted before use. You have now tried to avoid breaking the slag by removing the garbage, such as. B. is described in German Patent No. 75322, melted in a flame furnace and then granulated the liquid slag. This process has proven to be uneconomical because it requires too much fuel to be added. Attempts have then been made to melt the garbage in a shaft furnace, but this is also disadvantageous since the mechanical properties of the garbage, namely the collapse of the same to a mass which is impenetrable for the combustion air.

   Causes malfunctions in the furnace.

   The aforementioned German patent also states that artificial melts can be treated using the method described. Compared to this well-known
