charge motion. It is well known that ball milling efficiency varies during the lifetime of the shell liner. For instance the mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty.
