worden, um an dem anderen Ende in geröstetem, gedarrtem oder getrocknetem Zustande die Trommel wieder zu verlassen, die Erteilung der veränderlichen Tourenzahl während des Betriebes. Bei aoichcn Apparaten wurde bisher der Transport des Gutes durch die von aussen oder innen geheizte Trommel mittels einer an der Rotation der letzteren teilnehmenden Schnecke oder einer sonstigen mit der Trommel zusammenhängenden inneren Einrichtung bewirkt.
Da nun die Tourenzahl der Trommel sich nach der Art des zu behandelnde Materiales richtet, während die Gesamtdauer des Prozesses, d. i. die Zeit, welcho ein Teilchen des Gutes braucht, um von einem Ende der Trommel zum anderen zu gelangen, entsprechend der jeweiligen Wärmezufuhr gewählt werden solt, so ergab sich bei den bisherigen Vorrichtungen mit feststehendem unveränderlichen Verhältnis zwischen der Tourenzahl der Trommel und der Geschwindigkeit der fortschreitenden Bewegung des Gutes der Übelstand, dass während der Perioden stärkerer Wärmeentwicklung das Gut verbrannt wurde, während der Perioden geringerer Wärmeentwicklung hingegen in unfertigem Zustande die Tronunel vorliess.
Dieser Übelstand wird der vorliegenden Erfindung gemäss dadurch beseitigt, dass die Tourenzahl der Fördervorrichtung unabhängig von der mit einer gewissen, der Art des Gutes angepassten Geschwindigkeit rotierenden Trommel vermittels einer Vorrichtung bekannter Art während des Betriebes innerhalb weiter Grenzen gehindert und demgemäss der jeweiligen Wärmeentwicklung der Feuerung angepasst werden kann.

to leave the drum at the other end in a roasted, parched or dried state, the issuing of the variable number of revolutions during operation. In other apparatuses, the transport of the goods through the externally or internally heated drum has been effected by means of a screw participating in the rotation of the latter or some other internal device connected to the drum.
Since the number of revolutions of the drum depends on the type of material to be treated, while the total duration of the process, i. i. the time it takes a particle of the good to get from one end of the drum to the other should be selected according to the respective heat input, was the result of previous devices with a fixed invariable relationship between the number of revolutions of the drum and the speed of the advancing one Movement of the property the disadvantage that during periods of greater heat development the property was burned, while during periods of less heat development, on the other hand, the Tronunel let in unfinished condition.
This drawback is eliminated according to the present invention in that the number of revolutions of the conveying device is prevented within wide limits by means of a device of a known type during operation, regardless of the speed of the drum rotating at a certain speed adapted to the type of goods, and accordingly adapted to the respective heat development of the furnace can be.
