Der Hohlraum des Zylinders wird genützt, um die Antriebswelle, hier speziell die für das perforierte Gehäuse, zu schützen, wobei gleichzeitig eine einfache Verbindungsmöglichkeit zwischen Antriebswelle und Ge­ häuse geschaffen wird.The construction, in which the Mixing tool sits at the end of a hollow cylinder. The cavity of the Cylinder is used to drive the drive shaft, especially the for the perforated housing, while protecting a simple connection possibility between drive shaft and Ge housing is created.

Im folgenden wird ein Ausführungsbeispiel an Hand der Zeichnung näher erläutert. Es zeigt:The following is an embodiment with reference to the drawing explained in more detail. It shows:

Fig. 1 vertikaler Teilschnitt Fig. 1 vertical partial section

Die in Fig. 1 dargestellte Vorrichtung zeigt ein käfigartiges zy­ lindrisches Gehäuse 2, dessen Seitenwände 4, 6, 8 aus perforier­ ten Blechteilen bestehen. Diese Blechteile sind an ihren Kanten von Stützteilen 10, 12, 14 gehalten und stabilisiert. An den oberen und unteren Seitenwänden 6, 8 sind Elemente 16, 18 ange­ ordnet, die die Mahlkörper 20 und das Mahlgut 22 aktivieren. Zum Nachfüllen von Mahlkörpern 20 oder zum Austausch der gegebenen­ falls abgearbeiteten geschraubten Elemente 16, 18, 24 oder beim Wechsel des gesamten Gehäuses, der beim Austausch der Mahlkörper 20 hinsichtlich ihres Durchmessers notwendig werden kann, ist die obere Seitenwand 6 mit Schrauben 26 an den Stützteilen 12 befestigt. Hierzu ist zusätzlich zu den Schrauben 26 nur die Schraube 30 zu lösen, die das gesamte Gehäuse 2 fest mit der Antriebswelle 28 verspannt. Die Schraube 30 zieht den Zapfen 32, der etwas kürzer ist als das Stützteil 10 dick, in die Bohrung 34 und zentriert damit das Gehäuse 2 zur Antriebswelle 28. Die An­ triebswelle 28, die im Endbereich des Hohlzylinders 36 mit einem Lager 38 versehen ist, steht mit einem nicht dargestellten An­ trieb in Verbindung. Durch die Rotation des Gehäuses 2, dem Pfeilverlauf entsprechend, entsteht eine Zirkulationsströmung, wobei das Mahlgut 22 von oben und unten durch die Seitenwände 6, 8 in den Innenraum 40 des Gehäuses gelangt, hier unter dem Ein­ fluß der von den Mahlkörpern erzeugten Scherkräfte bearbeitet wird und durch die Seitenwände 4 zurück in den dargestellten Be­ hälter strömt. Zwischen den Seitenwänden 6 und dem Hohlzylinder 36 ist ein Spalt 42, durch den Mahlgut 22 in den Innenraum 40 fließt. Der scheibenförmige Ansatz 44 mit den Elementen 24 stellt insgesamt das Mischwerkzeug 46 dar.The device shown in Fig. 1 shows a cage-like cylindrical housing 2 , the side walls 4 , 6 , 8 consist of perforated sheet metal parts. These sheet metal parts are held and stabilized at their edges by support parts 10 , 12 , 14 . On the upper and lower side walls 6 , 8 elements 16 , 18 are arranged, which activate the grinding media 20 and the grinding stock 22 . To refill grinding media 20 or to replace the screwed elements 16 , 18 , 24 , if worked, or when changing the entire housing, which may be necessary in terms of their diameter when exchanging the grinding media 20 , the upper side wall 6 is provided with screws 26 on the support parts 12 attached. For this purpose, in addition to the screws 26, only the screw 30 has to be loosened, which firmly clamps the entire housing 2 to the drive shaft 28 . The screw 30 pulls the pin 32 , which is somewhat shorter than the support part 10 thick, into the bore 34 and thus centers the housing 2 to the drive shaft 28 . At the drive shaft 28 , which is provided in the end region of the hollow cylinder 36 with a bearing 38 , is connected to a drive, not shown, in connection. The rotation of the housing 2 , corresponding to the direction of the arrow, creates a circulation flow, with the regrind 22 coming from above and below through the side walls 6 , 8 into the interior 40 of the housing, here under the influence of the shear forces generated by the grinding media and flows through the side walls 4 back into the container shown Be. Between the side walls 6 and the hollow cylinder 36 there is a gap 42 through which ground material 22 flows into the interior 40 . The disk-shaped extension 44 with the elements 24 represents the mixing tool 46 overall.

In besonderen Fällen kann das Mischwerkzeug 46 auch am Ende eines Hohlzylinders sitzen, der mit einem Antrieb verbunden ist. Durch das Rotieren des Hohlzylinders wird dessen äußere Oberfläche weitgehend von Ablagerungen freigehalten. Auf Grund unterschied­ licher Drehzahlen bzw. entgegengesetzter Drehrichtung von Ge­ häuse 2 und Mischwerkzeug 46 läßt sich der Energieeintrag in die Vorrichtung erhöhen.In special cases, the mixing tool 46 can also sit at the end of a hollow cylinder which is connected to a drive. By rotating the hollow cylinder, its outer surface is largely kept free of deposits. Due to differing speeds or opposite direction of rotation of housing 2 and mixing tool 46 , the energy input into the device can be increased.
