A blocking slab for a pulp grinder, which blocking slab comprises a striplike frame to be mounted between a wall of a grinding chamber in the grinder and a grindstone, said frame being parallel to the axle of the grindstone. In order to prevent splinters and chips from getting out of the grinding chamber, the frame is provided with a longitudinal retaining edge facing to the peripherical surface of the grindstone. The retaining edge has at least one longitudinal recess, which is limited by two longitudinal retaining ribs, to prevent splinters and chips from getting out of the gap between the grindstone and the blocking slab. |
