Calcining processes for natural and synthetic gypsum | Grenzebach
The hammer mill, being a shorttime 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, precrushed natural gypsum, or a mixture of both.
