Abstract
The cutting comprises a drive disc, over whose periphery detachable secured rods 12, preferably having a square cross-section, are distributed at equal spacings and are aligned parallel to the drum axis. Between each pair of adjacent rods a blade box 42 is inserted which bears all replaceable wearing parts 56, 74, 80, these being directed into the drum interior. In operation each blade box rests againt the rods, owing to plane surface contact when these rods have a polygonal or, preferably, square cross-section.
