2016-12-19 chines and processes. One option is direct calcining in a Pfeiffer vertical roller mill of the type MPS-GC (Fig. 2). In this process, the gypsum is dried and ground to the required fineness of the plaster in the mill. Thanks to the relatively high temperature level in the gypsum calcining mill, the gypsum is simultaneously calcined.

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 is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water. Typically, free water is removed in an initial process at approximately 45℃ and crystalline bound water is removed in a second process at 120-180℃.

2020-3-3 Use of Gypsum. Gypsum is a widely used industrial material and building material. Gypsum (CaSO 4 2H 2 O) can be calcined and grinded to obtain β-type hemihydrate gypsum (2CaSO 4 H 2 O), that is, building gypsum, also known as cooked gypsum or plaster. The model gypsum can be obtained when the calcination temperature is 190 °C, and its fineness and whiteness are higher than that of ...
