Provided are methods and systems for introducing a wet gypsum accelerator or other high viscosity production additive to an aqueous dispersion of calcined gypsum in a discharge apparatus downstream of a stucco mixer in which the dispersion was prepared. These methods and systems are useful in the production of various gypsum products such as board including wallboard and ceiling tiles.

L~invention concerne des procédés et des systèmes permettant d~introduire un accélérateur de gypse humide, ou tout autre additif produisant une viscosité élevée, dans une dispersion aqueuse de gypse calciné se trouvant dans un appareil de décharge en aval d~un mélangeur de stucco dans lequel la dispersion a été préparée. Ces procédés et systèmes se révèlent utiles lors de la production de produits de gypse variés tels qu~un panneau comprenant un panneau mural et les carreaux de plafond.
