    Large Ball Mill Scale Up Factors to be Studied Relative to

    Ballmills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to themillless efficiently than smaller diameter mills, particularly when the large mills carry 40% by volumeballcharges. This paper will explore factors used in scaling upballmills, showing where the advantages of one factor can possibly be negated by another factor.
