ABSTRACT:
An apparatus and method for screening wood pulp and other fibrous fluid suspensions. The apparatus and method relate to rebuildable, modular screen cylinders for screening thick pulp slurry in pulp and paper applications. The screen sections of the modular screen cylinder of the present invention are of a nonwelded construction. A lap joint according to the present invention is provided in each screen section connecting the ends of the individual sections when the screen sections are rolled into cylindrical shape. As a result, the lap joint of the current invention provides for a nonwelded, modular screen cylinder which is less expensive to manufacture and provides for increased wear life and durability as compared to similar screen baskets previously known.
