derselben angeordneten Fallöffnung 22, von wo das Gut auf die Platte 4 fällt und auf diese Weise von Platte zu Platte durch die öffnungen 23, 24, 25, 26,27 und 28.
Die Gase gehen den umgekehrten Weg durch dieselben Öffnungen bis zur Austrittsöffnung.
Die Verbindung zwischen den verschiedenen Platten, die wie erwähnt, voneinander voll- kommen unabhängig sind, wird durch einen vom Profil der Einfassungsringe 19 gebildeten Ringkanal 29 hergestellt, in welchen ein Zylinder 30 eintaucht, der durch den nach unten verlängerten Rand der oberen Platte gebildet wird. Der Ringkanal wird mit Erzklein, Sand oder anderem - pulverförmigen Material oder auch mit einer Flüssigkeit angefüllt, zu dem Zweck, eine möglichst vollkommene Abdichtung gegen das Austreten von Gasen oder Eintreten von Luft herzustellen.
Der Betrieb des Ofens kann je nach Belieben kontinuierlich oder intermittierend sein. Die Rotationsgeschwindigkeit aller oder der einzelnen Platten wird nach Bedarf eingestellt.
Die Heizung kann für jede Vorrichtung besonders vorgesehen sein, es kann aber auch für eine Reihe von Apparaten eine gemeinschaftliche Heizung vorgesehen werden.
EMI2.2
ermöglicht es, im Innern des Ofens Metallteile vollkommen fortzulassen, welche in einer schwefligen Atmosphäre bei einer Temperatur, die das Rösten sulfidischer Erze erfordert, nur geringe Lebensdauer besitzen, selbst wenn man besondere Reguliermassnahmen trifft.
Eine Abkühlung erübrigt sich im vorliegenden Fall vollkommen. wodurch Heizmaterial gespart wird. Die Ofenkonstruktion erleichtert Reparaturen, da ein Auf-und Abmontieren schnell vorgenommen werden kann. Schliesslich bewirkt die Vorrichtung nach vorliegender Erfindung

EMI2.1
The same arranged drop opening 22, from where the material falls onto the plate 4 and in this way from plate to plate through the openings 23, 24, 25, 26, 27 and 28.
The gases go the opposite way through the same openings to the outlet opening.
The connection between the various plates, which, as mentioned, are completely independent of one another, is established by an annular channel 29 formed by the profile of the mounting rings 19, into which a cylinder 30 is immersed, which is formed by the edge of the upper plate extended downwards . The ring channel is filled with ore, sand or other - powdery material or with a liquid, for the purpose of creating as perfect a seal as possible against the escape of gases or the entry of air.
The operation of the furnace can be continuous or intermittent, as desired. The rotation speed of all or the individual plates is adjusted as required.
The heater can be specially provided for each device, but a common heater can also be provided for a number of devices.
EMI2.2
makes it possible to completely leave out metal parts inside the furnace which, in a sulphurous atmosphere at a temperature that requires the roasting of sulphidic ores, have a short lifespan, even if special regulating measures are taken.
A cooling is completely unnecessary in the present case. which saves heating material. The furnace construction makes repairs easier, since assembly and disassembly can be carried out quickly. Finally, the device according to the present invention works
