Large Ball Mill Scale Up Factors to be Studied Relative to

Large Ball Mill Scale Up Factors to be Studied Relative to

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 Scale Up Paul O. Abbe 174

Ball Mill Scale Up Paul O. Abbe 174

The rule of thumb for mill scale up is approximately 1-(√D/√d) where d is the diameter of the smaller mill and D the diameter of the larger mill. So going from a 12 lab scale mill to a 24 mill, 1-(√24/√12) = 0.4, so the larger mill may perform as much as 40% more efficiently.
