Kettle 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 ...
Dehydration processes can be conducted in kettle calciners, rotary dryers or roller mills, when grinding and calcining are combined. Kettle calciners are applied extensively in typical gypsum manufacturing processes ( Reichardt and Sander, 2006; Dvorkin and Dvorkin, 2011 ).
A Claudius Peters EM Mill is at the heart of a gypsum processing system, combining the functions of grinding, drying calcining and classifying the gypsum in one unit. For fine raw materials such as synthetic gypsum sources the Horizontal Impact Calciner allows direct calcining without grinding.
