Separators and classifiers send larger particles so that they can be sent back to mill for further grinding. Separators or classifiers with higher efficiency separate larger particles more accurately and thereby reduce over-grinding and decrease mill energy consumption. By replacing the external separator to ball mills with higher efficiency external separators, energy consumption in the mill

Changing the separator to a high efficiency type brings about better residue value (on 45 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.
