Abstract

Bei einem Verfahren zur Feinstzerkleinerung von minerali­ schen Stoffen, insbesondere von mineralischen Roh­ stoffen, im trockenen Zustand, unter Verwendung einer Planetenmühle, deren mindestens zwei jeweils mit sich in axialer Richtung erstreckenden Hub­ leisten versehene Mahlrohre gegenüber ihrer Umlauf­ bahn jeweils einen 1,5- bis 4-fach kleineren Durch­ messer aufweisen und mit einer solchen Umlauffrequenz betrieben werden, daß die auftretenden Fliehkräfte zwischen 2,5 und 15 g betragen, wird eine größere Wirtschaftlichkeit der Zerkleinerung dadurch er­ zielt, daß die Achsen der Mahlrohre der Planetenkugel­ mühle zur Horizontalen geneigt angeordnet werden und das Verhälltnis der Umlauffrequenz Mahlrohrbahn/Mahlrohr 0,4 bei 0,8 eingestellt wird. In a process for the fine grinding of minerali substances, especially mineral raw materials fabrics, when dry, using a planetary mill, at least two of which are each with stroke extending in the axial direction provide provided grinding tubes in relation to their circulation a 1.5 to 4 times smaller passage have knives and with such a rotation frequency be operated that the centrifugal forces that occur be between 2.5 and 15 g, a larger one Economics of shredding through it aims that the axes of the grinding tubes of the planetary ball be arranged inclined to the horizontal and the ratio of the circulation frequency grinding tube track / grinding tube 0.4 is set at 0.8.
