Abstract

The invention relates to a method for grinding materials of different granular size, in which particles of material to be ground, which are thrown off over the edge of a grinding dish (6), are transported upwards in a helical flow close to the housing wall with the aid of a gas-conducting arrangement (19) which generates a twisting or rotating flow. Under the influence of centrifugal force and gravity, a particle flow is formed essentially from external granular material which, as a deaerated dense flow (17), is not involved in the actual grinding and sifting process and is extracted at least in part from the grinding/sifting space. An extraction arrangement (25) is arranged on the housing wall in the radial direction above the grinding path and connected to a mechanical conveying arrangement, in particular for guiding back into the grinding/sifting space. <IMAGE>
