PCT No. PCT/DK86/00095 Sec. 371 Date Apr. 23, 1987 Sec. 102(e) Date Apr. 23, 1987 PCT Filed Aug. 26, 1986 PCT Pub. No. WO87/01304 PCT Pub. Date Mar. 12, 1987.The cutters (9) in a cutting grinder have according to the invention the shape of a rectangular parallelepiped which can be partly inserted into co-operating box-shaped sockets in the surface of the drum (8). The cutters (9) are retained by balls (14) which by means of a pin (13) being screwed in through the outer face of the plate (9) are pressed into a groove (7) arranged in the side of the socket. It is thereby possible to replace or to turn the cutters (9) by simply screwing out the pin (13) and so avoid the hard and difficult process of welding the cutters to the drum. It is thus possible to lower maintenance costs of the cutting grinder substantially just as it is possible according to requirements to mount cutters of different shape and number. The cutting grinder thus becomes universal.
