    "In the dry grinding of cement clinker to a fine powder in which for example ninety percent or more of the particles are reduced to a fineness below that of a 200 mesh screen, it has been found that further fine grinding is extremely difficult and the energy input is out of all proportion to the further production of fine particles. This seems to be due to the fact that when the bulk of the

    Aug 19, 2021The final product - cement - is obtained by grinding the clinker to a fine powder, in a cement mill together with some 3-5% of gypsum. The gypsum is a necessary additive in order to retard the setting time of cement. Without the addition of gypsum, the cement would harden immediately with the addition of water.
