Gypsum is a non-metallic mineral, found in rock form. It is composed of 79.1% calcium sulphate and 20.9% water, by weight. Chemists call it Hydrous Calcium Sulphate, and as there is one molecule of calcium sulphate combined with two molecules of water. It has the chemical formula CaSO 4 2H 2 0. By volume this works out to nearly 50% water in

Cement milling and gypsum dehydration Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4 .H 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4 )

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)

Gypsum stone is crushed into particles of less than 30mm in diameter, and the particles are grinded in the mill. After grinding, the powder which passes the classifier would be transformed into the furnace for calcinations, while the rest which doesn't meet the fineness requirements would return to the miller for a

Pfeiffer MPS mill where the material is dried and simultaneously ground to the required fineness for plaster. Subsequently, the ground and dried gyp-sum is delivered to the gypsum kettle (Fig. 3).The kettle filled with finely ground gypsum is heated from outside. To improve the heat input, hot gas pipes lead the hot gas straight through the kettle (Fig. 4). The escaping crystal water causes the gypsum to start fluidizing as soon as
