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 another factor.
Ball Mill 5 5 Rt 5 5 Ft
Large mill (D>5.0 m (16.5 ft)) performance has been successfully predicted from small scale batch experiment for grinding kinetics and an RTD correlation for transport using population balance models.The effect of ball size must be properly taken into account in the scale-up. A design method that combined the kinetic scale-up findings and the transport of material through the mill has been ...
