Description

Verfahren zur Verfeinerung von Ton und Kaolin Zusatz zum Patent 816 216 Das Hauptpatent 816 216 bezieht sich auf die Be#haridlung von Tonsuspensionen, insbesondere Kaolinsuspensionen, und besteht darin, daß diese Suspensionen zum Zwecke der Verfeinerung und der Befreiung von qualitativmindernden Begleitmineralien unter Einwirkung von Ultraschall gesetzt werden. Dabei wird in Anlehnung an die bisherigen Verfeinerungsverfahren das Material im Schlärtimprozeß,hehandelt, der besonders bei Kaolin erhebliche Wasserrnengen beansprucht.Process for the refinement of clay and kaolin Addition to patent 816 216 The main patent 816 216 relates to the treatment of clay suspensions, in particular kaolin suspensions, and consists in using these suspensions for the purpose of refinement and the removal of qualitative accompanying minerals under the action of ultrasound be set. Based on the previous refinement processes, the material is treated in the slaughtering process, which, especially with kaolin, requires considerable amounts of water.

Die Erfindung zeigt hier nun ein Verfahren, das die Veredelung des Rohstoffes beziehungsweise seine Verfeinerung in der Kornzusammensetzung nicht mehr wie in der Kaolinindustrie bisher üblich innerhalb der Naßaufbereitung vornimmt, sondern den Kaolin oder Ton in seiner ursprünglichen Form als Roherde vor der Reinigung von den übrigen Begleitmaterialien oder nach dem Ausschlämm- und Entwässerungsprozeß in trockenem Zustand dem Veredelungsverfahren unterwirft.The invention now shows a method that the refinement of the Raw material or its refinement in the grain composition no longer as has been customary in the kaolin industry up to now within the wet processing, but the kaolin or clay in its original form as raw earth before cleaning from the remaining accompanying materials or after the elutriation and drainage process subjected to the finishing process in a dry state.

Mit dieser Behandlung des Rohstoffes in trockenem Zustand ' ohne jede Wasserbeimischung oder gegebenenfalls mit nur geringen Flüssigkeitszugaben beschreitet die Erfindung einen ganz neuen Weg in der Aufbereitung des Kaolins, bei dein die großen Schlämmwassermengen an Fortfall kommen und der Kaolin in fester Form oder wenigstens in nicht flüssigem Zustand den Verfeinerungs- und Reinigungswirkungen ausgesetzt wird. Dabei kann der Kaolin sowohl roh als auch jeder beliebigen Schlämnistufe entnommen, getrocknet der Beschallung unterworfen werden.With this treatment of the raw material in the dry state , without any admixture of water or, if necessary, with only a small amount of liquid added, the invention takes a completely new approach in the treatment of kaolin, in which the large amounts of waste water are wasted and the kaolin in solid form or at least in non-liquid form Condition is exposed to the refining and cleaning effects. The kaolin can be taken raw or any slurry level, dried and subjected to sonication.

Die Behandlung kann ferner in stückigem oder gemahlenem Zustand des Kaolins bzw. des Tons vorgenommen werden und erfolgt erfindungsgemäß durch Einwirkung von Ultraschallwellen verschiedener Intensität auf diesen. Abgesehen von der stückigen Form, welche große Leistungen beim Beschallen erfordern würde, wird man in der Regel den gemahlenen Zustand vorziehen und das Material in feinst verteilter Form einem Beschallungsraum zuführen. Die Zuführung erfolgt dabei zweckmäßig unter Druck, welcher das Material in staubförmiger Form durch den U ' Itraschallerzeuger zwingt und im Verein mit den dort erzeugten Schallwellen die Aufspaltung der Teilchen bewirkt, wobei die Einwirkung auf die größeren Teilchen intensiver als auf die kleineren sein kann, so daß auch eine Vergleichmäßigung der Korngrößenzusammensetzung erzielt wird.The treatment can also be carried out in the lumpy or ground state of the kaolin or the clay and is carried out according to the invention by the action of ultrasound waves of different intensities on them. Apart from the lumpy form, which would require a high level of sonication performance, the ground state is usually preferred and the material is supplied to a sonication room in a finely divided form. The feed is expediently under pressure which forces the material in atomized form through the U 'Itraschallerzeuger and causes in conjunction with the generated there soundwaves the splitting of the particles, the effect on the larger particles more intense than can be on the smaller, so that a homogenization of the grain size composition is achieved.

Dieser Durchblasevorgang ermöglicht es ferner, das Durchgangsmaterial nach erfolgter Beschallung nach verschiedenen Korngrößen abzusetzen, indem an der Ablaufstelle ein genügend weiter Raum für die Spezifizierung der abfallenden Teilchen zur Verfügung gestellt wird.This blow-through process also enables the passage material after the sonication has been carried out according to different grain sizes by adding to the Drainage point a sufficiently wide space for the specification of the falling particles is made available.

Neben diesem ausgesprochenen Trockenverfahren lassen sich die Beschallungen auch an feuchten oder angefeuchteten Materialien durchführen, die als Roherde oder auch als bereits ausgeschlämmtes Fertigprodukt (Fertigkaoliii) angeliefert werden. Die Beschallung kann somit unabhängig von den verschiedenen Vorreinigungsgraden z. B. vor den mechanischen oder chemischen Schläminvorgängen erfolgen.In addition to this pronounced dry process, the sonication can be used also perform on damp or moistened materials that are called raw earth or can also be delivered as a finished product (ready-made kaoliii) that has already been washed out. The sonication can thus be independent of the various pre-cleaning levels z. B. take place before the mechanical or chemical Schläminvorgänge.
