BEDPLATES HAVING GRADUATED OPENINGS FOR PULP PROCESSING UNITS
A bedplate for a pulp processing unit includes a plate having an upper axial surface, a lower axial surface, and plurality of openings extending through the plate from the upper axial surface to the lower axial surface. Each of the plurality of openings has a shape, a size, and an angle. The shape is the cross-sectional shape, the size is equal to the largest cross-sectional dimension, and the angle is an angle formed between a centerline of each of the plurality of openings and an axial line parallel to a center axis of the bedplate. The shape, the size, the orientation of the shape, the angle, or combinations thereof of the plurality of openings varies depending on a location of the opening on the bedplate. A pulp processing unit comprising the bedplate is also disclosed.
