Description

1fehrkammermühle zum Mahlen von Thomasschlacke Bisher wurde Thomasschlacke in Kugelfallmühlen geschrotet, in denen sich das in der Schlacke enthaltene Eisen ansammelte. Die Kugelmühle mußte von Zeit zu Zeit angehalten werden, damit das Eisen herausgelassen werden konnte. Die vorliegende Erfindung will den hierin liegenden Nachteil beseitigen, und zwar soll in der folgenden Weise gearbeitet werden.1 multi-chamber mill for grinding Thomas slag Up until now, Thomas slag was used crushed in ball mills, in which the iron contained in the slag is accumulated. The ball mill had to be stopped from time to time to keep the iron could be let out. The present invention seeks to provide those herein Eliminate disadvantage, namely should be worked in the following manner.

Es wird mit einer langen Vorschrotmühle gearbeitet, die am Ende Austrittsroste hat, deren Weite so groß ist, daß die Stahlkugeln in der Mühle gehalten werden, während das Eisen mit dem geschroteten Schlackengrieß aus der Mühle austreten kann. Da die Schlacke auf dem langen Weg durch die Mühle genügend geschrotet wird, während das Eisen seine Form beibehält, wird man an den Auslauf der Mühle eine Trennvorrichtung des Eisens von der Schlacke iri Form entsprechender Siebzylinder anbringen können. Die geschrotete Schlacke tritt durch die Siebe hindurch und wird zur Feinmühle weitergeleitet. Das Eisen wird nach dem Durchgang durch den Siebzylinder abgeleitet. Falls man Schrotmühle und Feinmühle in einem Rohr ausführt, kann die Ausscheidungseinrichtung auch in einer besonderen Kammer zwischen den beiden Mahlräumen untergebracht werden.A long pre-grist mill is used with an exit grate at the end whose width is so large that the steel balls are held in the mill, while the iron can emerge from the mill with the crushed slag. Because the slag is crushed enough on the long way through the mill while the iron maintains its shape, one becomes a separator at the outlet of the mill of the iron from the slag in the form of corresponding sieve cylinders. The crushed slag passes through the sieves and is passed on to the fine mill. The iron is diverted after passing through the screen cylinder. If you have a gristmill and fine mill in a tube, the separation device can also be in a special chamber between the two grinding chambers.

Eine beispielsweise Ausführungsform der Erfindung wird in der beiliegenden Zeichnung veranschaulicht. Abb. i stellt einen Längsschnitt durch die Mühle dar, Abb.2 einen Querschnitt nach A-B der Abb. i.An exemplary embodiment of the invention is shown in the enclosed Drawing illustrates. Fig. I shows a longitudinal section through the mill, Fig.2 a cross-section according to A-B of Fig. I.

In dem vorliegenden Beispiel ist die Mühle als eine Dreikammermühle dargestellt, mit den Kammern a, b und c. Aus der ersten Kammer, der Vorschrotkammer a, gelangt das vorgeschrotete Gut durch die Rostplatte d und wird durch Schaufeln f in die Mitte der zweiten Kammer eingeführt. Diese zweite Kammer ist als Siebkammer ausgebildet und trägt ein Sieb g, durch welches das Gut selbst, die Schlacke, hindurchfällt und mittels entsprechender Schaufeln i in die zweite Kammer c befördert wird. Am Ende dieser Siebkammer bzw. der Siebplatten g sind kleine Zylinder A angeordnet, welche das nicht durch das Sieb hindurchfallende Eisen aus der Mühle befördern. Um diese Zylinder A zum Auswerfen des Eisens ist ein Ring k angeordnet.In the present example, the mill is shown as a three-chamber mill, with chambers a, b and c. From the first chamber, the pre-shredded chamber a, the pre-shredded material passes through the grate plate d and is introduced into the center of the second chamber by shovels f. This second chamber is designed as a sieve chamber and carries a sieve g through which the material itself, the slag, falls and is conveyed into the second chamber c by means of corresponding blades i. At the end of this sieve chamber or the sieve plates g, small cylinders A are arranged which convey the iron that does not fall through the sieve out of the mill. A ring k is arranged around these cylinders A for ejecting the iron.
