Description

Die Erfindung betrifft eine Vorrichtung zum Mahlen-von Masseiigütern mit einem mit S&lagleisten besetzten schnell umlaufenden Rotor und einer diesen umgebenden, auf ihrer Innenfläche mit als Prallplatten wirkenden# Hubleisten besetzten langsam umlaufenden Trommel, und das -Neue besteht darin, daß- die Trommel wenige, beispielsweise zwei oder vier Hubleisten aufweist. Vorteilhaft erhält bei einer Trommel mit vier Hubleisten auch der Umläufer vier Schlagleisten, und zweckmäßig ist es, wenn der innere Rand der Hubleisten umgebogen ist.The invention relates to a device for grinding bulk goods with a fast rotating rotor fitted with S & lag strips and one of these surrounding, occupied on their inner surface with acting as baffle plates # lifting strips slowly rotating drum, and the -new is that- the drum few, for example, has two or four lifting strips. Advantageously received at a Drum with four lifting bars, the rotor also has four beating bars, and useful it is when the inner edge of the lift bars is bent.

Bei den bekannten Anlagen ähnlicher Art hat man eine sehr große Anzahl von Hubleisten und Schlagleisten vorgesehen, wodurch zwischen ihnen verhältnismäßig kleine Taschen - gebildet wurden und die von den Leisten gebildeten radialen Wandungen dieser Taschen nur - in geringem Maße gegeneinander schräg standen. Diese Taschen setzensich schnell zu, und die Mahlwirkung wiird dadurch beträchtlich herabgesetzt. Durch die Beschränkung der Leistenzahl erstrecken sich die Taschen in der Umfangsrichtung über erheblichgrößere Bögen, und die Leisten der einzelnen Taschen bilden miteinander Winkel von etwa gd'. Hierdurch ist ein Festsetzen mit Mahlgut mit Sicherheit verhütet.In the known systems of a similar type, a very large number of lift bars and blow bars have been provided, whereby relatively small pockets were formed between them - and the radial walls of these pockets formed by the bars only - were slightly inclined to one another. These pockets clog up quickly and the grinding efficiency is thereby considerably reduced. By limiting the number of strips, the pockets extend in the circumferential direction over considerably larger arcs, and the strips of the individual pockets form angles of approximately gd 'with one another. As a result, a clogging with grist is definitely prevented.

Die Zei : chnung stellt ein - Ausführungsbeispiel der Erfindung dar und zeigt schematisch in Abb. i eine Mahlvorrichtung, in . The Zei: tatements represents a - represents embodiment of the invention, showing schematically in Figure i is a grinding apparatus, in..

Abb. 2 einen Schnitt nach Linie II-II der Abb. i. In dem von Lagerrollen i in Umlauf versetzten Gehäuse:2 läuft das Schleuderwerk 3 mit Schlagleisten 4 mit hoher Geschwindigkeit um. Das mit Mahlkörpern gemischte Gut wird durch die Rohrleitung 5 eingeführt und durch die im Gehäuse:2 angeordneten vier Hubleisten 6, deren nach der Achse hin gerichtete Enden 7 umgebogen sind, dem Schleuderwerk 3 fortlaufend zugeführt. Die umgebogenen Enden-7 dienen als Angähleudeiflächen, auf welche das von dem Schleuderwerk 3 abgeschleuderte Gut aufprallt. Die Austragung des -gefeinten Gutes erfolgt-durchdie Leitung 8. Fig. 2 is a section along line II-II of Fig. I. In the housing set in circulation by bearing rollers i: 2, the centrifugal mechanism 3 with beater bars 4 rotates at high speed. The mixed with grinding media material is introduced through conduit 5 and through the housing: the ejection mechanism 3 continuously fed 2 arranged four lifting bars 6, which according to the axis directed towards the ends are bent. 7 The bent-over ends 7 serve as contact surfaces on which the material thrown off by the centrifugal mechanism 3 impacts. The discharge of the refined material takes place through the line 8.

Die Mühle'gem,äß är Erfindung ist besonders geeignet für ein Mahlen mit eingeführten Mahlkörpern, da sie an keiner Stelle tote Ecken enthält, in denen sich diese festklemmen k8nnen.The mill according to the invention is particularly suitable for grinding with introduced grinding media, as it does not contain any dead corners in which these can get stuck.
