EMISSION FACTOR DOCUMENTATION FOR AP-42 SECTION 11.16
Calcination occurs at approximately 120° to 150°C (250° to 300°F) and 0.908 megagrams (Mg) (1 ton) of gypsum drying, grinding, and calcining are performed in heated impact mills. In these mills hot gas contacts gypsum as it is ground. The gas dries and calcines the ore and then conveys the stucco to a product cyclone for collection

pdf gypsum powder calcining plant
gypsum calcining mill is about 2-4 minutes. This is short in comparison to the time it takes in the gypsum kettle which may range between 60 and 200 minutes. Due to the kettle being heated indir-ectly the specific thermal energy requirement is about 20 % higher than when the gypsum is cal-cined directly in the gypsum calcining mill ( Tab 1).
