Early Experience with Large Balls Mills at Mount Lyell
Some twelve months of operation at Mount Lyell, using two large diameter ball mills as a two-stage grinding circuit indicated a short- fall in the grinding capability compared with design criteria. Breakage, particularly at coarser sizes, was less efficient than with the previously used grinding circuit comprising a large number of smaller diameter mills. This paper describes both old and new equipment, puts forward the facts as they are presently known, and lists the attempts made to overcome the problem.
