Cement Kilns: Size Reduction and Grinding

In cement grinding, the tube mill established itself as a complement to the ball mill, and they were installed in pairs, with the ball mill discharging directly into the tube mill inlet. They often worked on a common drive. Tube mills were also used in combination with flat stones, the latter being run "light" so that stone wear was minimised, and greatly increasing their output. During

Cement mill - Wikipedia

These have been used for many years for the less exacting raw-milling process, but recently roller mills, in combination with high-efficiency 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 wid
