The holder flanges are positioned parallel to each other and concentrically with a centre lengthwise axis (2). The grinding lamellae (6) protrude outward beyond the holder flanges between which they are each positioned. Several grinding lamellae are assembled into a pack (7) and are spaced out round the periphery of the support (1). The bottom (9) of the grinding lamellae of each pack are compressed at right-angles to their planes by bolts (13), and joined to the support by the bolts. |
