Description
Kolloidmühle Die Erfindung bezieht sich auf Kolloidmühlen, die so ausgeführt sind, daß ein kegelstumpfförmiger Rotor, der außen mit Nuten versehen ist, innerhalb eines entsprechend kegelig ausgeführten Statorgehäuses, das in seiner inneren Mantelfläche ebenfalls Nuten aufweist, umläuft.Colloid Mill The invention relates to colloid mills which do so are designed that a frustoconical rotor provided with grooves on the outside is, within a correspondingly conical stator housing, which is in his inner circumferential surface also has grooves, rotates.
Das zu verarbeitende Material bewegt sich durch Fliehkraftwirkung zwischen der Statorgehäuse- und Rotorkegelfläche hindurch und wird während des Durchganges bearbeitet. Nach dem Austritt aus dem Arbeitsspalt fließt das Material bei allen bekannten Mühlen aus dein Mahlspalt in eine darunter angeordnete Sammelrinne und von hier aus ab.The material to be processed moves by centrifugal force between the stator housing and rotor cone surfaces and becomes during the passage processed. After exiting the working gap, the material flows in all of them known mills from your grinding gap in a collecting channel arranged below and from here onwards.
Dieser bekannten Ausführung haften bei der Verarbeitung zäher Materialien erhebliche Mängel an, und zwar dadurch, daß das Mahlgut durch den sehr feinen Ringspalt mit geringem Querschnitt und die sich nach dem Austritt hin in der Tiefe verringernden Nuten hindurchgequetscht werden muß, wodurch eine starke Erwärmung bei gleichzeitig geringer Mengenleistung entsteht.This known design adhere when processing tough materials significant defects, namely that the grist through the very fine annular gap with a small cross-section and which decrease in depth after the exit Grooves must be squeezed through, whereby a strong heating at the same time low volume output.
Diese Nachteile werden gemäß der Erfindung dadurch vermieden, daß der untere Teil der Statorwand mit Schlitzen versehen ist, die in die entsprechend hochgezogene Sammelrinne münden.These disadvantages are avoided according to the invention in that the lower part of the stator wall is provided with slots that fit into the corresponding raised collecting gutter open.
Diese Ausbildung ergibt eine wesentliche Verbesserung, da die starke Pressung des Materials im unteren Bereich der Arbeitsteile erheblich verringert und die Men-enleistung der Maschine erhöht wird, ohne daß die Feinheitsleistung in unzulässigem Maße abnimmt.This training results in a substantial improvement since the strong one The pressure of the material in the lower area of the working parts is significantly reduced and the output of the machine is increased without reducing the fineness decreases to an unacceptable degree.
Die Schlitze können axial oder unter einem Winkel zur Achse verlaufen. In weiterer Ausgestaltung der Erfindung können die Schlitze zusätzlich unter einem Winkel ziir Radialen verlaufen. Dadurch ergeben sich an den Kanten. die gegen die Rotorschneidkanten weisen, scharfe Messerkanten, die in Zusammenarbeit mit den Rotorschneidkanten das Material vor dem Eintritt in die Schlitze zerschneiden.The slots can be axial or at an angle to the axis. In a further embodiment of the invention, the slots can additionally under one Angles to radials. This results at the edges. the against the Rotor cutting edges have sharp knife edges that work in conjunction with the rotor cutting edges cut the material before entering the slots.
In der Zeichnung ist eine Kolloidmühle gemäß der Erfindung beispielsweise dargestellt, und zwar zeigt F i g. 1 eine Seitenansicht der zur Hälfte geschnittenen Mühle und F i g. 2 eine Aufsicht mit Schnitt in Höhe der Austrittschlitze.In the drawing a colloid mill according to the invention is for example shown, namely shows F i g. 1 is a side view of the half cut Mill and F i g. 2 a plan view with a section at the level of the outlet slots.
Der konische Rotor 1 ist in einem entsprechenden Stator 2 angeordnet, der in ein Lagergehäuse 3 eingeschraubt ist, das eine Sammelrinne 4 aufweist. Der Stator ist in seinem unteren Bereich mit Schlitzen 5 versehen, wodurch am Innenkegel des Statormantels Schneidkanten 6 entstehen.The conical rotor 1 is arranged in a corresponding stator 2, which is screwed into a bearing housing 3 which has a collecting channel 4. Of the The stator is provided with slots 5 in its lower area, whereby the inner cone of the stator casing cutting edges 6 arise.
