摘要： Method and apparatus for converting wet synthetic gypsum from a flue desulphurization process (FGD) to easily handled and metered briquettes by mixing a hydraulic additive such as by-pass dust from a cement kiln with synthetic gypsum and allowing the heat from the resulting hydraulic reaction to reduce the water content of the mixture to a formable consistency without adding external heat to the mixture as it is formed into briquettes.

摘要： The present invention is directed to a gypsum panel with reduced calcination and a method of making such gypsum panel. For instance, in one embodiment, the gypsum panel comprises a gypsum core and a first facing material and a second facing material sandwiching the gypsum core, wherein the gypsum core includes gypsum and a calcination inhibitor. The methods of the present invention are directed to making the aforementioned gypsum panels.
