Gypsum board, drywall or plasterboard is a building product used in modern construction for efficient, cost effective fire protection that can be easily installed and decorated. The process to produce gypsum board generally consists of calcining and or grinding gypsum powder, forming a gypsum panel product and drying off excess water.
As used here, an impact mill is a process unit used to dry, grind, and calcine gypsum simultaneously. q References 4-5,16. Emission factor units = kg/m2. Based on 13-mm board thickness and 1.2 m board width. For other thicknesses, multiply the appropriate emission factor by 0.079 times board thickness in mm. r References 4-5,16.
This invention relates to a process for making gypsum board comprising feeding a paper backing sheet and a fiber-glass or plastic woven or non-woven scrim material in alignment to a board forming station, separating the paper and the scrim, feeding a high density calcium sulfate hemihydrate slurry into the trough formed between the paper and the scrim, and subsequently compressing the paper ...

Gypsum produced as a byproduct of the flue-gas desulfurization process at electric power plants provides an economical, environmentally sound raw material for making high-quality gypsum board. Two types of paper are used in the production of most drywall, and
These gypsum deposits became sedimentary rock beds when they were cemented together. Dissolved particles and decayed matter carried by water were left between gypsum grains, making the natural cement that holds sediment together. Other sand and soil was deposited on top of the gypsum layer and pressed down on it creating the gypsum bed.
