Methods of and systems for adding a high viscosity gypsum additive to a post-mixer aqueous dispersion of calcined gypsum

摘要

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.
