The disc mill comprises a revolving (30) and a stationary (12) grinding disc. The revolving grinding disc (30) is arranged on a shaft. In both grinding discs (12, 30), radial grooves are formed into which webs (67) of a hard material are inserted. Along these radial webs (67), rows of pockets (41-46 and 61-66) separated from one another by transverse fins (51, 52) are located. The width of the grinding gap present between the two grinding discs (30, 12) is determined by the webs (67) together with the transverse fins (51, 52). The webs of the revolving grinding disc (30) are of such a width that, during the revolving motion of the grinding disc, they momentarily cover the pockets (61-66) of the stationary disc (12). In this disc mill, the fibres of the starting material are separated from one another without excessive shortening. <IMAGE> |
