Description

Die Erfindung betrifft eine Schleudermühle, bei der von dem aus dem Schleuderrad frei niederfallenden Mahlgut nach Emporheben mittels eines Becherwerkes oder ähnlichen Hubmittels das Grobe ausgesichtet und zur nochmaligen Mahlung in den oberhalb des Schleuderwerkes liegenden Einlauf zurückgebracht wird, und das Neue besteht darin, daB die Mühle in Federn gehalten wird und mit Einrichtungen versehen ist, die die Mühle in Schwingungen versetzen.The invention relates to a centrifugal mill in which from the Centrifugal wheel freely falling grist after being lifted up by means of a bucket elevator or similar lifting means sifted out the coarse and regrind in the inlet located above the centrifugal mechanism is brought back, and that What is new is that the mill is held in springs and with facilities is provided that make the mill vibrate.

Die Erfindung bietet die Möglichkeit, zu der normalen Zerkleinerung eine solche durch Schwingung hinzuzufügen, die durch die Aufhängung des Mahlgehäuses in Federn und die Einrichtungen, die die Mühle in Schwingungen versetzen, gegeben ist.The invention offers the possibility of normal comminution to add one by vibration, which is caused by the suspension of the grinder housing in springs and the devices that make the mill vibrate is.

Die Zeichnung stellt schematisch ein Ausführungsbeispiel der Erfindung dar und zeigt eine solche Zerkleinerungsanlage im Schnitt.The drawing shows schematically an embodiment of the invention and shows such a crushing plant in section.

Das Mahlgehäuse r ist mit den Federn 2 gehalten und wird beispielsweise von dem Wechselmagneten 3 in Schwingungen versetzt. Durch den Einlauf 4 gelangt das Aufgabegut in die Mühle und in den Bereich des Schlagrotors 5, welcher das Gut vorzerkleinert. Das Gut erfährt im Zusammenhang mit den ebenfalls in Schwingung versetzten Prallplatten 6 eine zweifach wirkende Zerkleinerung, zu der die schräge Austragsfläche 7 ebenfalls beiträgt. Durch den Stutzen 8 gelangt das Brechgut in das schöpfende Becherwerk 9, welches das Gut auf ein Schwingsieb zo oder einen Sichter leitet, um Feines vom Groben zu trennen. Der Überlauf wird der vorstehend beschriebenen Zerkleinerung erneut zugeleitet, während das genügend gefeinte Gut durch die Schnecke 1r ausgetragen wird.The grinding housing r is held with the springs 2 and is for example set in vibration by the alternating magnet 3. Passed through the inlet 4 the feed material in the mill and in the area of the beater rotor 5, which the material pre-shredded. The good experiences in connection with the likewise in vibration offset baffle plates 6 a double-acting crushing to which the inclined Discharge area 7 also contributes. The material to be crushed passes through the nozzle 8 the scooping bucket elevator 9, which zo the material on a vibrating screen or a sifter conducts to separate fine from coarse. The overflow becomes that described above Comminution is fed back in, while the sufficiently refined material is passed through the auger 1r is carried out.
