The effects of grinding temperature on the grindability and quality of cement were discussed mainly from the standpoint of the action of gypsum. A mixture of normal portland cement clinker and natural gypsum (SO 3 =1.7% in the resulting cement) was ground in the test mill at 25-200°C, for 20-100 min. which is provided with a heating device.

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 ...
