Abstract
A grinder for use in wet grinding having a roller or wheel rolling on a circular track and elastically pressed thereon. The materials to be ground are subjected to several layer on bed grinding operations to enable the rational utilization of this type of grinder. During the time between two successive grinding operations in the grinder, water or another liquid is introduced by nozzles to the materials. The materials are drained and/or dried by a screen so as to reduce water content to below 20% in volume.
