Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4#189;H2O), commonly called stucco.

To produce gypsum board, crushed natural gypsum or synthetic gypsum is heated or calcined to dehydrate the feedstock. Next the calcined gypsum is mixed with water and additives to form a slurry which is fed between continuous layers of recycled paper on a long board machine.
Gypsum plaster is a white cementing material made by partial or complete dehydration of the mineral gypsum, commonly with special retarders or hardeners added. Applied in a plastic state (with water), it sets and hardens by chemical recombination of the gypsum with water.
#0183;#32;Introduction Gypsum is a naturally occurring, white powdery mineral with the chemical name calcium sulphate Dihydrate (CaSQ4#183;2H2O). Gypsum products used in dentistry are based on calcium sulphate hemihydrate (CaSO42)2#183;H2O. Their main uses are for casts or models, dies . 4.

GYPSUM PRODUCTION PROCESS. Gypsum production plant is a calcination unit for production of powdered gypsum (calcined). Gypsum which is coming from pit is brought to the appropriate size with gypsum jaw crusher. The hammer crusher then moves to the kiln feed size. As a result of crushing process, the gypsum size is 010 mm and the crushed

#0183;#32;If plaster or gypsum is heated to between 130 #176;C, (266 #176;F) and 180 #176;C (350#176;F), hemihydrate is formed, which will also reform as gypsum if mixed with water. [21] [22] On heating to 180 #176;C (350#176;F), the nearly waterfree form, called anhydrite (CaSO 4 #183; n H 2 O where n = 0 to ) is produced. Anhydrite reacts slowly with water to return to the dihydrate state, a property exploited in some
