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. The paper will propose …

factor of 1.25 that accounts for the difference in grinding efficiency of a SAG mill versus a ball mill. The original Barratt papers do not specify values to use for PC and PR, but we can use the same values as Table 1 of 10 000 µm and 2100 µm, respectively. The value T80 is the "synthetic" transfer size between the SAG mill and ball mill ...

Balls which do not bounce high are less efficient as they have lost energy. If theoretically a ball could not lose any energy during a bounce, it would bounce back to of the height it was dropped from. Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few.
