Description

Die Erfindung bezieht sich auf solche Mehrkammermühlen, bei denen die Vormahlkammer an einen Windsichter angeschlossen ist, dessen Rückstand in die Vormahlkammer und dessen Feingut in die Feinmahlkammer der Mühle zurückgeleitet wird. Bei manchen Sorten von Mahlgut, insbesondere bei hochwertigen Farben, erweist es sich als notwendig, 'den Feinheitsgrad des· aus der Feinmahlkammer der Mühle austretenden Gutes einer noch weiteren Steigerung der Feinheit zu unterwerfen, so daß ein Erzeugnis erhalten wird, das unfühlbar fein ist. Hierdurch entsteht z. B. bei Lackfarben ein besonders hoher Glanz. Die Erfindung ist in technischer Beziehung dadurch gegeben, daß an den Auslauf der Feinmahlkammer ein zweiter Sichter angeschlossen ist, dessen Rückstände ebenfalls wieder in die Feinmahlkammer zurück-The invention relates to such multi-chamber mills in which the pre-grinding chamber is connected to an air classifier, the residue in the pre-grinding chamber and whose fine material is returned to the fine grinding chamber of the mill. With some varieties of regrind, especially with high-quality paints, it turns out to be necessary 'the degree of fineness of the material emerging from the fine grinding chamber of the mill to subject it to a further increase in delicacy, so that a product is obtained becomes that is imperceptibly fine. This creates z. B. with paints a special high gloss. The invention is given in technical terms in that to the outlet a second classifier is connected to the grinding chamber, whose residues are also connected back to the grinding chamber-

Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung.The figure shows an embodiment of the invention.

Das Frischgut wird bei diesem Beispiel der Vormahlkammer zugeführt, das vorgemahlene Gut wird auf einen Sichter (Windsichter oder Siebsichter o. dgl.) geführt, der das Grobe in die Vormahlkammer zurückschickt und das Feine der Nachfeinkammer zuführt. Das aus der Nachfeinkammer austretende Gut wird durch einen weiteren Sichter (Windsichter) nachgeprüft, der das fertige Feinmehl aussondert und das gröbere zur Nachfeinung zur Mühle (Nachfein- oder Vormahlkammer) zurückgibt.In this example, the fresh material is fed to the pre-grinding chamber, the pre-ground material Well, a sifter (air sifter or sieve sifter or the like) is performed, which Sends the coarse back to the pre-grinding chamber and the fine feeds to the refining chamber. The material emerging from the refining chamber is passed through another sifter (wind sifter) checked, which separates the finished fine flour and the coarser for refining returns to the mill (refining or pre-grinding chamber).

An Stelle der in der Abbildung angegebenen zwei Fördervorrichtungen (Becherwerke o. dgl.) kann zur Vereinfachung der Anlage auch eine einzige Fördervorrichtung, z. B. ein Becherwerk mit doppelten Becherketten, verwendet werden, das beide Mahlerzeugnisse getrennt fördern kann.Instead of the two conveying devices (bucket elevators o. The like.) To simplify the system, a single conveyor device, for. B. a Bucket elevator with double bucket chains, which can be used for both grinded products can promote separately.
