Gypsum (C 0 G 100) is the softest material among the studied; however, it has a sharp feed PSD and low size, which can increase the resistance to grinding. This is seen by gypsum's initial fineness (n = 1.42), which has a narrower PSD than limestone (n = 0.70). The uniformities of the materials were very similar after being ground by the ball ...The center groove allowed air to escape from the material. Grinding pressure was concentrated under the outer zone of the roller, allowing for most efficient operation. Cement with gypsum and limestone, referred as CGL, were prepared as shown in Table 2. The surface area obtained was in the range 2751−2885 cm 2 /g.

Ground Calcium Carbonate(GCC) Grinding Mill; Gypsum Powder Solution . Gypsum, after being calcined and finely ground, becomes building gypsum, also known as plaster, stucco.
