Description

Die Erfindung betrifft eine Prallmühle mit einem zum Schleudern dienenden Umläufer hoher Drehzahl, bei :der Druckluft durch im Mahlkammer-Boden vorgesehene Öffnungen in die Mahlkammer eingeführt und das Gemahlene durch die abziehende Luft einem Sichter zugeführt wird, aus dem das Grobe wieder in die Mahlkammer gelangt, und das Neue besteht darin, daß .der Teil des Mahlkammerbodt:ns, auf dem sieh Mahlgut absetzt, durch eine luftdurchlässige Platte .gebildet wird. Damit wird ein Exnporwirbeln dieses abgesetzten. Gutes erreicht, so 4aß es wieder in die Mahlzone gerät und dann von dem abziehenden Luftstrom wird. Um dries zu erreichen, hat man bereits Druckluftleitungen für Form von Düsen in den Mahlkammer-Boden einmünden lassen. Aber damit wird keine gleichmäßig über den ganzen Boden verteilte Wirkung hervorgebracht, vielmehr wird an einzelnen Stellen das Gut überhaupt vor einem Absetzen gehindert, an anderen Stellen aber werden sich bi.l-.dendre Niedersetzungen ,gar nicht beeinflußt.The invention relates to an impact mill with one used for centrifugation High-speed rotor, with: the compressed air through provided in the grinding chamber floor Openings are introduced into the grinding chamber and the ground material through the extracting air is fed to a sifter from which the coarse is returned to the grinding chamber, and what is new is that the part of the bottom of the grinding chamber on which you can see grist settles, is formed by an air-permeable plate. This creates an export vortex this deposed. A good thing is achieved, so it gets back into the grinding zone and then from the withdrawing air stream. To achieve three, you already have compressed air lines for the form of nozzles open into the bottom of the grinding chamber. But that won't do effect evenly distributed over the whole floor is produced, rather is In some places the property is prevented from settling at all, in others However, there are two or three lowering positions that are not influenced at all.

Luftdurchlässige Kammerböden sind .nun an sich zwar bei derartigen Mühlen bekannt, aber sie .haben stets dazu gedient, das Gefeinte abzusieben. Es tritt also kein Luftstrom durch sie in den Mahlrau. ein.Air-permeable chamber floors are .well in themselves with such Mills are known, but they have always served to sift through the finer things. It so there is no air flow through them into the Mahlrau. a.

Damit die Luft störungsfrei einströmen kann, kann man die Durchlässe in der Platte in an sieh bekannter Weise dierart gestalten, daß sie kein Gut von oben mach unten; hindurchfallen oder -rieseln lassen. Damit wird eine weit bessere Verteilung und Einleitung der Luft erzielt, als wenn man diese durch Einzelöffnungen größerer Weite ' hindurch gehen läßt,- durch die außer Fremdkörpern gegebenenfalls auch noch gröbete Gutsteile entgegen dem Luftstrom ausfallen, wag die Luftzuführung stört und beeinträchtigt.The passages can be used so that the air can flow in without interference in the plate in a manner known per se in such a way that it is no good of above do below; let fall or trickle through. That makes a far better one Distribution and introduction of the air is achieved as if one had it through individual openings larger width 'can go through, - through the other than foreign bodies if necessary Even coarse good parts fall out against the air flow, dare the air supply bothers and affects.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Durch den Einlauf I wird der Prall.mühle das zu zerkleinernde Gut zugeführt, .gelangt in den Wirkungskreis der Schlagwerlazeuge 2 und wird von diesen an die Prallplatte 3 geschleudert. Zur Verringerung des Verschleißes können derartige Platten Aushöhlungen haben. Das Grobe gelangt durch das Rohr 4 in den Mahlraum zurück, das Feine geht über den Sichter 5 zur B.unkerung o:d.,dgl. über den Druckstutzen 7 wird durch eine mit Öffnungen versehene Platte B der Mahlkammner von unten Druckluft zugeführt.Through inlet I, the impact mill becomes the material to be shredded supplied,. gets into the sphere of action of the impact tools 2 and is from these hurled against the baffle plate 3. To reduce wear, such Plates have cavities. The coarse comes back through the pipe 4 into the grinding chamber, the fine goes through the classifier 5 to B.unkerung o: d., like. via the pressure port 7 is compressed air from below through a plate B provided with openings of the grinding chamber fed.

Durch Beschickung der Mahlkammer mit Heizgasen kann die Prallmühle gleichzeitig zum Trocknen verwendet werden.By charging the grinding chamber with heating gases, the impact mill can can be used for drying at the same time.
