Abstract
A blocking slab is used in a grinding chamber of a pulpwood grinder having a rotatable grindstone. The pulpwood grinder is suitable for reducing wood into pulp and objectionable shims and shives. The blocking slab includes a retaining side extending the length of the grindstone for permitting the passage of pulp. The blocking slab also includes a plurality of ribs forming a collecting channel proximate the retaining side and extending the length of the grindstone for collecting shims and shives therein. The plurality of ribs are angled for directing the shims and shives collected in the collecting channel toward the ends of the grindstone thus providing further reduction of the shims and shives.
