Suited mainly for Portland cement and with limitations for composite cement; the ground and dried additive is fed to the tube mill or mill outlet. In the first stage (press with separator) the cement is ground 1'000 1'500 [cm2/g] below desired product fineness and in the tube mill to the end fineness.

In the value stream map of cement manufacturing the raw mill feeding is an intermediate activity between Prehomogenization and raw milling, and has not been discussed separately by most of the authors. However, in my opinion it remains and must remain as of pivotal importance, so far as the quality assurance is considered.

Changing the separator to high efficiency type bringa about better residue value (on 45 s micron) for the same Blaine. Alternatively, the cement can be ground to a lower Blaine with the same residue, which determines the strength of cement. In most cases the layout permits replacing the separator to a high efficiency type.

In 1904, Krupp produced a selfcontained cement mill using a ball mill and their version of the Askham separator in closed circuit, but I think this was never used in Britain. However, from the mid 1890s, ball mills were used in combination with tube mills (see below) and this setup became the normal cement milling installation until 1920.
