Abstract
An arrangement for fastening a grindstone (1) of a pulp grinder to a rotatory shaft (2). In the arrangement, the radial forces acting on the grindstone are transmitted from the fastening flange (3) of the grindstone (1) to the rotatory shaft (2) by means of a support member (12) which transmits the radial forces from the fastening flange (3) through the support member (12) to the rotatory shaft (2) in such way that they do not substantially affect the threads (8), (9) of the nut (7) and the rotatory shaft (2).
