DEM modelling of liner evolution and its influence on grinding
网页2011年2月1日There is an interesting kick-up in wear rate at the rear of the lifter wave for a new liner. This is explained through inspection of Fig. 3, where it can be seen that many balls impact directly on the liner for the t1 period. These high energy impacts (balls dropping about 6 m) will be on the rear of the wave liners.

Semi-autogenous grinding (SAG) mill liner design and development
网页throughout the life of the liner. For fixed-speed mills, a common practice is to design shell lifters with some (slight) overthrow when new such that the liner “wears in” to come “on grind” early in the wear cycle with mill performance falling away towards the end of shell lifter wear life. The aim is to maximize the wear-life of the
