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.

2014-7-31 Mill power draw prediction can be carried out using Morrell’s power model for tumbling mills (Morrell, 1998). Bond method The established technique for determining power requirements for ball mills is the Bond method (Bond, 1961). This method also involves the application of some ‘efficiency factors’ as described by Rowland (1975).
