Description

Kolloidmühle mit kegelstumpfförmigem Rotor Die Erfindung bezieht sich auf eine Kalloidmühle mit kegelstumpfförmigem Rotor, der mit geringem Spiel in einem entsprechend geformten Gehäuse umläuft, und bei der die Mahlflächen in mindestens drei in der Durchtrittsrichtung des Mahlgutes hintereinanderliegende Mahlzone. unterteilt sind, deren Oberflächenprofilierung in dieser Richtung immer feiner wird. Bei einer bekannten Mühle dieser Art sind sämtliche Mahlzonen mit Systemen, paralleler und in der Durchtrittsrichtung verlaufender Nuten versehen. Die Nuten sind dabei von Zone zu Zone feiner und entsprechend dichter nebeneinanderliegend.Frustoconical Rotor Colloid Mill The invention relates to on a calloid mill with a frustoconical rotor with little play in one correspondingly shaped housing revolves, and in which the grinding surfaces in at least three grinding zones lying one behind the other in the direction in which the material to be ground passes. divided whose surface profiling is getting finer and finer in this direction. At a known mill of this type are all grinding zones with systems, parallel and Provided grooves extending in the direction of passage. The grooves are from Zone to zone finer and accordingly closer to one another.

Es hat sich jedoch gezeigt, daß auch durch die feinsten Nuten der letzten, Zone immer noch nicht genügend zerkleinerte Teilchen hindurchgelangen können, so daß das fertige Mahlgut nicht den höchsten Anforderungen an die Mahlfeinheit entspricht.However, it has been shown that even through the finest grooves last, zone still not enough crushed particles can get through, so that the finished grist does not meet the highest demands on the fineness of the grind is equivalent to.

Man hat in der letzten Zone von, Kolloidmühlen dieser Art schon vollkommen ungenutete, geschliffene Flächen am Rotor und Stator vorgesehen,, in die die Uten der vorhergehenden Janen auslaufen. Hierbei hat sich aber ergeben, daß sich das Mahlgut vor diesen Flächen staut und daher stark erwärmt oder sogar verbrennt.In the last zone of, colloid mills of this type are already perfect Ungrooved, ground surfaces are provided on the rotor and stator, in which the Uten of the previous Janen expire. But it turned out that the Regrind accumulates in front of these surfaces and is therefore strongly heated or even burned.

Diese Mängel werden erfindungsgemäß dadurch vermieden, daß die Mahlflächen der ersten Zonen Nuten, die der letzten Zone jedoch eine durchgehende Nuten vermeidende Aufrauhung. aufweisen. Bei einer solchen Mühle kann in den mit Nuten versehenen, immer feiner werdenden Zonen eine allmähliche gute Vorzerkleinerung erzielt werden, ohne daß dabei Stauungen. auftreten, die ein Erhitzen des Mahlgutes zur Folge haben, während die letzte Zone, deren Mahlflächen eine grundsätzlich andere Beschaffenheit aufweisen, dem Mahlgut die letzte Feinheit vermittelt.These deficiencies are avoided according to the invention in that the grinding surfaces grooves in the first zone, but the last zone avoids continuous grooves Roughening. exhibit. With such a mill, the grooved, A gradual good pre-shredding can be achieved in areas that are becoming finer and finer, without congestion. occur that result in the ground material being heated, while the last zone, whose grinding surfaces are fundamentally different in nature show the final fineness of the grist.

Die Aufrauhungen können auf mechanischem, chemischem oder elektrischem Wege erzielt werden.The roughening can be mechanical, chemical or electrical Ways can be achieved.

Es sind allerdings auch bereits Kolloidmühlen mit mehreren immer feiner werdenden Mahlzonen bekannt, bei denen. die Mahlflächen sämtlicher Zonen infolge Verwendung keramischer Mahlleörper durchgehende Nuten vermeidendeAufrauhungen aufweisen. Diesen Mühlen ermangelt jedoch, die günstige kühl mahlende Wirkung der mit Nuten versehenen Mahlflächen, so daß sie im ganzen, wesentlich wärmer mahlen, was in vielen Anwendungsfällen die Verwendbarkeit einer Kolloidmühle ausschließt.However, colloid mills with several are already finer and finer known grinding zones where. the grinding surfaces of all zones as a result Use of ceramic grinding bodies to have roughening that avoids through grooves. However, these mills lack the beneficial cool grinding effect of those with grooves provided grinding surfaces, so that they grind on the whole, much warmer, which in many Applications excludes the usability of a colloid mill.

PATENTANSPRUCH: Kollo-idmühle mit kegelstumpfförmigem Rotor, der mit geringem Spiel in einem entsprechend geformten Gehäuse umläuft, und bei der die Mahlflächen in mindestens drei in der Durchtrittsrichtung des Mahlgutes hintereinanderlieggende Mahlzonen unterteilt sind, deren; Oberflächenprofilierung in dieser Richtung immer feiner wird, dadurch gekennzeichnet, daß die Mahlflächen, der ersten Zonen Nuten und die der letztem. Zone eine Aufrauhung aufweisen, die durchgehende Nuten vermeidet. In Betracht gezogene Druckschriften: Deutsche Patentschrift Nr. 436 368; französische Patentschrift Nr. 1070 360; USA.-Patentschrift Nr. 2 402 170. PATENT CLAIM: Colloid mill with a truncated cone-shaped rotor which rotates with little play in a correspondingly shaped housing, and in which the grinding surfaces are divided into at least three grinding zones lying one behind the other in the direction in which the material to be ground passes. Surface profiling is getting finer and finer in this direction, characterized in that the grinding surfaces, the first zones grooves and those of the last. Zone have a roughening that avoids through grooves. Documents considered: German Patent No. 436 368; French Patent No. 1070 360; U.S. Patent No. 2,402,170.
