Abstract (en)

[origin: WO9739829A1] The invention relates to wet grinding and grinders comprising a roller or wheel (4) rolling on a circular track (18) and elastically pressed thereon. To enable the rational utilization of this type of grinder for wet grinding, the materials to be ground are subjected to several layer or bed grinding operations. During the time in the grinder between two successive grinding operations, water or another liquid (nozzles 12) is added to the materials, which are then drained and/or dried (screen 8) so as to reduce their water content to below 20 % in volume.
