Optimization of mill performance by using

liner design purposes. Many simulation tools exist to obtain the necessary information about media trajectories. Data are used to avoid the risk of liner and ball damage by projecting balls directly on the shell liner. Figure 3b illustrates this issue. Obviously, a good liner design and the right operating

The typical piece of the magnetic liner is about 11.81 inches (300 mm) long and weighs 37.48 lbs (17 kg) and can be easily moved by hand, making installation much easier and safer than conventional The ball chips are attracted to the liner and form

Research on Non-Uniform Wear of Liner in SAG Mill

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].
