Large Ball Mill Scale-Up Factors to be Studied Relative to ...

Abstract. Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by ...

Energy Use in Comminution. Grinding activities in general (including coarse, intermediate, and fine grinding) account for 0.5 pct of U.S. primary energy use, 3.8 pct of total U.S. electricity consumption, and 40 pct of total U.S. mining industry energy use. Large energy saving opportunities have been identified in grinding in particular.
