Embodiment Construction

[0053] The present invention provides various embodiments of cementitious slurry mixing and dispensing assemblies that can be used in the manufacture of products, including cementitious products such as gypsum wallboard. Embodiments of a cementitious slurry mixing and distributing assembly constructed in accordance with the principles of the present invention may be used in a manufacturing process and include a flow divider in the discharge conduit mounted to the mixer to effectively divide the flow of the multiphase slurry A single stream - such as an aqueous foamed gypsum slurry comprising a gas phase and a liquid phase - enters the splitter from the mixer such that at least two separate streams of the multiphase slurry exit the splitter.

[0054] Embodiments of cementitious slurry mixing and distributing assemblies constructed in accordance with the principles of the present invention may be used to mix and distribute a slurry, such as an aqueous calcined gypsum slurry, onto...

Abstract

A flow splitter (200) can include an inlet conduit (202) and first and second outlet conduits (204, 206) separated by a junction portion (210). The inlet conduit (202) can include an inlet end (203) and a junction end (205). The inlet conduit (202) is disposed along a main flow axis (75) extending between the inlet end (202) and the junction end (205). The inlet end (203) defines an inlet opening (207). The junction end (205) defines first and second junction openings (209, 211). The first junction opening (209) is disposed in spaced relationship to the second junction opening (211). The junction portion (210) is disposed at the junction end (205) of the inlet conduit (202) between the first and second junction openings (209, 211). The junction portion (210) includes a substantially planar wall region (219) that is substantially perpendicular to the main flow axis (75). The flow splitter (200) can be placed in fluid communication with a cementitious slurry mixer (102) and a slurry distributor (104) with the flow splitter (200) disposed therebetween.
