"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 …
