US Patent for Burr for preparing a homogeneous

An improved burr for sharpening the grinding surface of a pulpstone includes a novel tooth configuration for better wear of the burr and enhanced grinding properties of the pulpstone. The profile configuration of the burr teeth has a truncated tip portion in the form of a rounded tip portion, a flat tip portion, or an obtusely angled tip portion to avoid a sharply pointed tip.An investigation into topographic changes in pulpstone,,An investigation into topographic changes in pulpstone grits and their impact on pulp quality during the stabilization process January 2008 Paperi Ja Puu 90(7):38-43Ground wood fiber length distributions :: BioResources,The top log dry solids content was 42%.
