Study on the Performance of Ball Mill with Liner

The breaking performance of the hemispherical lifter and the ladder lifter was poor, because the main pattern of motion was grinding rather than impact breakage. Secondly, the effects of the height–width ratio of the rectangular lifter, the height of the lifter and the number of lifters on the working efficiency of the ball mill were studied.

Study on the Performance of Ball Mill with Liner Structure

A performance evaluation was conducted on the breakage process in a ball mill along with DEM modeling in Ref. [13]. Using a representative non-round ore, simulation of particle breakage was conducted to study different concave profiles and mantles with DEM in Ref. [8]. DEM simulations were proven to be an effective way to solve ball mill
