Abstract
An additive injection system can be a part of a cementitious slurry mixing and dispensing assembly. The additive injection system can be used to inject an additive into an auxiliary slurry discharge conduit carrying a secondary flow of cementitious slurry produced in the assembly such that the secondary slurry stream is different from a main slurry stream discharged from a main slurry discharge conduit.
Claims20
A system for manufacturing a gypsum board, the system comprising:
- a mixer, the mixer including a housing and an agitator disposed within the housing, the housing has a first outlet and a second outlet, the agitator being configured to agitate water and calcined gypsum to form an aqueous gypsum slurry;
- a main discharge conduit, the main discharge conduit is in fluid communication with the first outlet of the mixer;
- a secondary discharge conduit, the secondary discharge conduit is in fluid communication with the second outlet of the mixer;
- and
- an additive injection system having an injection body and a port member, the injection body defining a slurry passageway and a port passageway, the slurry passageway comprising a portion of the secondary discharge conduit such that the slurry passageway is in fluid communication with the second outlet of the mixer, the port passageway in fluid communication with the slurry passageway, the port member defining an additive passageway, the port member removably connected to the injection body such that the additive passageway is in fluid communication with the port passageway.
An additive injection system for use in preparing a cementitious product via a mixer, the mixer including a housing and an agitator disposed within the housing, the housing has a first outlet and a second outlet, the agitator being configured to agitate water and a cementitious material to form an aqueous cementitious slurry, the additive injection system comprising:
- an injection body, the injection body defining a slurry passageway and a port passageway, the slurry passageway adapted to comprise a portion of a mixer secondary discharge conduit adapted to be in fluid communication with the second outlet of the mixer such that the slurry passageway is in fluid communication with the second outlet of the mixer, the port passageway in fluid communication with the slurry passageway;
- and
- a port member, the port member defining an additive passageway, the port member removably connected to the injection body such that the additive passageway is in fluid communication with the port passageway.
