Research on Non-Uniform Wear of Liner in SAG Mill

2020-11-27  movement of rocks and media in a dry ball mill based on the DEM [12]. Xu Lei used the DEM method to predict the wear and impact of each part of the liner’s lifter bar [13]. Zhen Xu used the DEM-FEM (Finite Element Method) coupling method to study the wear of the liner of the ball mill and analyzed the wear of four di erent surface liners [14].
