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 ...
