noch glühend ist, wenn auch nicht mehr so heiss, dass die niederrutschenden Schlacken weich bleiben. Diese erhärten also und kleben an jener Stelle an. Der Ansatz vermehrt sich in dem Masse, als von oben Schlacken nachrutschen, so dass sich nach kurzer Zeit ein Schlackenpfropfen i gebildet hat, durch den die untere Mündung der Muffel derart verengt wird, dass die Rückstände nicht mehr durchgehen. Der Reduktionsprozess erleidet infolgedessen eine Störung, denn die Beschickung kann nicht nachrutschen. Soweit lässt man es aber nicht kommen. Von Zeit zu Zeit hebt man durch Drehung des Ritzels/'die Weie ( und damit auch den Fräser c hoch, wobei Voraussetzung ist, dass sich die Spindel 9 dreht, die die Welle d bei der Drehung mitnimmt.
Der Fräser c arbeitet nun die durch den ursprünglichen Gehalt an Reduktionskohle verhältnismässig bröckeligen Ansätze i weg. Hierauf wird die Welle d wieder gesenkt, so dass der Fräser selbst nur kurze Zeit der hohen Temperatur ausgesetzt ist.
PATENT-ANSPRÜCHE :
1. Vorrichtung zur Beseitigung der an der unteren Mündung von stehenden Retorten bei der Zinkgewinnung erhärteten Schlacken, dadurch gekennzeichnet, dass ein sich drehender Bohrer oder Fräser und eine Transportvorrichtung (Schnecke) an der unteren Mündung der Retorten im Bereiche der sich ansetzenden Schlackenkrusten angeordnet sind.

is still glowing, although not so hot that the slag that slides down remains soft. So these harden and stick to that point. The approach increases to the extent that slag slides down from above, so that after a short time a slag plug i has formed through which the lower mouth of the muffle is narrowed in such a way that the residues no longer pass through. As a result, the reduction process suffers a malfunction because the feed cannot slide down. But you don't let it get that far. From time to time, by turning the pinion / 'the white (and thus also the milling cutter c) is lifted, with the prerequisite that the spindle 9 rotates, which takes the shaft d with it as it rotates.
The cutter c now works away the approaches i, which are relatively crumbly due to the original content of reducing carbon. The shaft d is then lowered again so that the milling cutter itself is only exposed to the high temperature for a short time.
PATENT CLAIMS:
1. Device for removing the slag hardened at the lower mouth of standing retorts during zinc extraction, characterized in that a rotating drill or milling cutter and a transport device (screw) are arranged at the lower mouth of the retorts in the area of the cinder crusts that build up.
