Paper mill sludge ash (PMSA), sewage sludge ash (SSA), and desulfurization gypsum (DG) were mixed and calcined by microwave radiation to acquire a product with higher hydration activity. The resulting mixture was used as a supplementary cementitious material to prepare backfill materials for mining.
calciners may be operated in either batch or continuous mode. In flash calciners, the gypsum is directly contacted with hot gases, and the stucco product is collected at the bottom of the calciner. At some gypsum plants, drying, grinding, and calcining are performed in heated impact mills. In these mills hot gas contacts gypsum as it is ground.

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 second grinding.
Thanks to the relatively high temperature level in the gypsum calcining mill, the gypsum is simultaneously calcined. When gypsum is calcined in an atmosphere sat- urated with water vapour at an overpressure of several bars, a-hemihydrate is formed ( Fig. 1). The outstanding feature of this plaster is a relatively regular crystal form.
Calcination of Gypsum was an accidental discovery as were its rehydration characteristics. Ancient man probably used lumps of Gypsum to enclose his fire. Some degree of calcination and softening occurred and when the fire was extinguished with water he noticed the lumps soon hardened.
