Static separator model. Grinding efficiency in ball mills depends on the classifying performance of air separators as explained in the study of (Klumpar and Slavsky, 1989) and (Kolacz, 1999). Their findings indicated that, energy consumption in ball milling can be reduced if the classification efficiency is sufficiently high.
The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative to the ball mill system and has increased its share of the market for cement mills over

For fine grinding lime hydrate lumps, grinding circuits comprising ball mills and separators are provided. Instead of separators, screening machines are used in case of coarse grinding. The fineness of the products can be set within wide limits (0.01 to 5 mm). The ground products are used in every sector of the lime industry.
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.
