Calcining processes for natural and synthetic gypsum ...

Calcination in a rotary kiln is a direct, long-time calcining process. During the process, the phases of the CaSO 4 x H 2 O system can be optimally adjusted. Rotary kilns are used for the calcining natural gypsum. In this process, pre-crushed natural gypsum is calcined in parallel flow with the flue gas.

Calcination Process Development Calcining Equipment

Equipment Used. Rotary kilns are used to carry out the calcination process. Depending on the process goals and the material to be processed, the kiln may be of the direct-fired, or indirect-fired type. It is also common to follow the calcination process with a rotary cooler. This efficiently cools the material after it has been calcined, so it ...

Gypsum boards from waste material: a cost effective

2018-2-15  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.
