## Large Ball Mill ScaleUp Factors to be Studied Relative to

Ball mills 55 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 another factor The paper will propose possible operating
