    Highefficiency SeparatorClassifier for Coal Grinding

    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.
