| Abstract: |
| Semi-autogenous grinding mill(SAG) is one of the important equipment in the field of grinding. In this paper, a SAG mill model of semi-industrial scale is established, because of the high frequency of existing SAG mill Based on the existing theory of abrasive wear and the wear pattern of Hertz-Mindlin with Archard Wear, the particles with different particle diameters under complex shape were established in EDEM software. DEM-FEM coupling analysis was carried out by using EDEM software and ANSYS software. The liner’s improvement is based on the test of foreign scholars and the stress distribution and wear of this simulation. The simulation results shows that the Stress concentration phenomenon decreased and the wear resistance of the liner is improved obviously by adopting the type of split Trapezoidal liner. The maximum average wear loss of the new liner is 30% lower than that of the original liner. |
