Description

Die Erfindung betrifft einen Prallzerkleinerer mit gegen Prallflächen gerichteten Mischdüsen für Luft und Gut. Die Prallflächen sind der Erfindung gemäß zwischen zwei Mischdüsen angeordnet, deren eine der Vorzerkleinerung dient und von oben nach unten gerichtet ist, während die andere Mischdüse der Nachzerkleinerung des herabfallenden Gutes dient und von unten nach obenThe invention relates to an impact crusher with directed against impact surfaces Mixing nozzles for air and goods. According to the invention, the baffles are between two mixing nozzles arranged, one of which is used for pre-shredding and from top to bottom is directed downwards, while the other mixing nozzle is re-shredding the falling Good serves and from the bottom up

to verläuft. Das ergibt eine besonders einfache und wirksame Gesamteinrichtung für Vor- und Nachzerkleinerung.to runs. This results in a particularly simple and effective overall device for and re-shredding.

Eine Ausführungsform ist in der Zeichnung veranschaulicht.One embodiment is illustrated in the drawing.

Das Rohgut gelangt von irgendeinem Bunker mittels der Förderschnecke k zu dem Mischrohr b, in das die Druckluftleitung c mündet, um so von oben gegen die obere Prallfläche eines Körpers α geschleudert zuThe raw material arrives from any bunker by means of the screw conveyor k to the mixing tube b, into which the compressed air line c opens, so as to be thrown from above against the upper impact surface of a body α

so werden. Die hierbei nicht genügend zerkleinerten Gutteilchen fallen auf den Boden des Behälters m, an dessen kegelförmiges Unterteil sich die Druckluftleitung η anschließt. Das hier sich sammelnde Gut wird durch denbe like that. The material particles which are not sufficiently comminuted fall to the bottom of the container m, to the conical lower part of which the compressed air line η is connected. The goods that are collected here are replaced by the

s5 Druckluftstrom in das Mischrohr ο und aus diesem von unten gegen die hier befindliche Prallfläche des Körpers α geschleudert. Die hier immer noch nicht genügend zerkleinerten Gutteilchen werden im Kreislauf wieder durch das Mischrohr α hochgeführt und erneut gegen den' Prallkörper geworfen. Der Feinstaub zieht durch den Auslaß i ab.s5 Compressed air flow into the mixing tube ο and thrown from it from below against the impact surface of the body α located here. The good particles, which are still not sufficiently comminuted here, are circulated back up through the mixing tube α and thrown again against the impact body. The fine dust is drawn off through outlet i .

Der Prallkörper α kann, wie dargestellt, mit vier Prallflächen ausgestattet und um eine Achse j drehbar sein, damit in an sich bekannter Weise nach Abnutzung der jeweils arbeitenden Flächen die beiden anderen Prallflächen durch Drehen des Körpers in die Gebrauchsstellung übergeführt werden können. Natürlich können die jeweils arbeitenden Prallflächen auch getrennt, also nicht an einem gemeinschaftlichen Körper angeordnetThe impact body α can, as shown, be equipped with four impact surfaces and be rotatable about an axis j so that, in a known manner, after the respective working surfaces have worn off, the other two impact surfaces can be moved into the position of use by rotating the body. Of course, the respective working baffles can also be arranged separately, that is, not on a common body
