Foamed gypsum board having voids distributed throughout the gypsum core
A system and method for introducing a slurry mixture for making gypsum board is disclosed. The system includes a mixer for mixing slurry and directing it to an exit gate, a foam injector for injecting foam into the slurry, and a canister connected to the mixer for inducing swirl to the slurry. The system also includes an elongated hose and an optional adapter for depositing the slurry onto paper to form the board. Ends of the elongated hose are coupled to the canister and to the inlet of the adapter. Slurry is directed from the canister, through the hose, and into the adapter for exiting its outlet. Optionally, a mixing boot and/or elbow joints may be included. Use of the hose and adapter enhances the flexibility of the system, including moving the mixer offline or adjacent to the paper or belt, and improves foam blending in the slurry mixture.
