Method and apparatus for pressurized calcination of

A method for calcining gypsum comprising: injecting gypsum into a pressurized reactor; injecting combustion gases and air into the pressurized reactor to create a fluidized bed of gypsum in the reactor; and heating the fluidized bed of gypsum in the pressurized reactor to sufficiently calcine the gypsum to form a calcined hemihydrate; wherein the heating is accomplished with a heat exchanger and wherein the method further comprises removing the calcined gypsum

Gypsum boards from waste material: a cost effective process

Waste gypsum boards contain up to 10 wt% water, which needs to be removed at the rotating drum dryer. The dry gypsum is led to a ball mill to reduce the particle size to create a d 50 of 0,1 mm. The very fine material is transported to the calciner. In the calciner gypsum dihydrate is converted to gypsum hemihydrate, which is also known as stucco.
