Abstract: A flow splitter can include an inlet conduit and first and second outlet conduits separated by a junction portion. The inlet conduit can include an inlet end and a junction end. The inlet conduit is disposed along a main flow axis extending between the inlet end and the junction end. The inlet end defines an inlet opening. The junction end defines first and second junction openings. The first junction opening is disposed in spaced relationship to the second junction opening. The junction portion is disposed at the junction end of the inlet conduit between the first and second junction openings. The junction portion includes a substantially planar wall region that is substantially perpendicular to the main flow axis. The flow splitter can be placed in fluid communication with a cementitious slurry mixer and a slurry distributor with the flow splitter disposed therebetween.

Abstract: A multi-piece mold for use in a method for making a slurry distributor includes a plurality of mold segments adapted to be removably secured together. The mold segments are configured such that, when the mold segments are assembled together, the assembled mold segments define a substantially continuous exterior surface adapted to be a negative image of an interior flow region of a slurry distributor molded thereupon. Each mold segment has a maximum cross-sectional area in a plane substantially transverse to a direction of movement of the mold segment along a removal path out of a respective opening of the molded slurry distributor. The maximum cross-sectional area of each mold segment is up to about 150% of the smallest area of the interior flow region of the molded slurry distributor through which the mold segment traverses when moving along the respective removal path.

Abstract: A slurry distributor can include a feed conduit and a distribution conduit in fluid communication therewith. The feed conduit can include a first and second feed inlets disposed in spaced relationship to each other. The distribution conduit can extend generally along a longitudinal axis and include an entry portion and a distribution outlet in fluid communication therewith. The entry portion is in fluid communication with the first and second feed inlets of the feed conduit. The distribution outlet extends a predetermined distance along a transverse axis. The first and second feed inlets each has an opening with a cross-sectional area. The entry portion of the distribution conduit has an opening with a cross-sectional area which is greater than the sum of the cross-sectional areas of the openings of the first and second feed inlets. The slurry distributor can be placed in fluid communication with a gypsum slurry mixer.
