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.

Rules of thumb Raw material: 1016 kWh/t (mill motor) target fineness: passing 200µm>99%, passing 90µm>88% depending upon burnability of raw mix) Cement: For a pure cement (95% clinker) at 3500 cm2/g, the mill motor consumption should be <40 kWh/t. (Clinker grindability: approx 32 kWh/t at 3000 cm2/g (mill motor).

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.
