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.

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. When gypsum is calcined in an atmosphere sat-
In the gypsum industry, CentriMils are used to increase the specific surface area (cm2/gram), or Blaine, of calcined gypsum. Blaine levels as high as 12,000 can be achieved using CentriMils. Reduced gypsum and water requirements result in a faster setting board which is stronger and up to 30% lighter, resulting in greatly reduced shipping ...
