gypsum calcining process
Calcining processes for natural and synthetic gypsum ...
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 100% moist FGD gypsum, 100% pre-crushed natural gypsum, or a mixture of both.
