Grinding and calcining of gypsum with Pfeiffer grinding plants

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).
