The hammer mill, being a short-time calcining system, grinds, dries, calcines and classifies the raw gypsum in a single step. The resulting stucco is suitable for the production of plasterboard, gypsum fiberboard and gypsum wall blocks. A hammer mill can process moist FGD gypsum, pre-crushed natural gypsum, or a mixture of both.

Rotary kilns, for gypsum calcination, are similar to cement kilns, but the main difference is that gypsum kilns are counter-flow compared to cement kilns. In gypsum kilns, the gypsum encounters a temperature of 600-650 °C when it is fed into the kiln and this temperature is decreases to around 150-160 °C at the kiln exit.
When gypsum is heated at about 150–160 °C, it loses approximately three-quarters of its water in a partial dehydration process and becomes hemihydrate gypsum (CaSO 4 •½H 2 O) or calcined gypsum; it is also known as beta gypsum (alpha gypsum is made by processing batches of gypsum under elevated pressure). Calcined gypsum or …

Most gypsum is calcined in gypsum kettles or in rotary kilns. According to Lippard (1949), a gypsum kettle consists of a cylindrical steel shell with a rounded bottom, which contains some kind of mechanically operated stirring device on the inside, and is heated from the bottom. Diameters range from 8 to 15 feet, and depths from 6 to 14 feet.
