    These have been used for many years for the less exacting rawmilling process, but recently roller mills, in combination with highefficiency separators, have been used for cement grinding The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient Energy consumption is typically half that of a ball mill However, the narrowness of the particle size distribution of the cement is problematic, and the process has yet to receive wide acceptance
