Currently the mining sector worldwide faces adverse conditions such as the decrease in the number of discovered deposits, the high cost of energy and an unstable world economy, which affect its operations economically. For this reason, technological innovation is the solution to optimize production and guarantee the sustainability of mining operations. Therefore, High Pressure Grinding Rolls (HPGR) are a currently preferred alternative due to their energy savings. electrical. However, the reduction of the useful life time in the coating of the rollers generates cost overruns to the annual maintenance budget recommended for the HPGR equipment, for this reason, the present investigation seeks to optimize the useful life time of the coating of the HPGR equipment, by applying the discrete element method (DEM) and the theory of abrasive wear of the coating with the Rocky DEM software. The application of the concepts of solution of the geometries and the sensitivity analysis of the height and diameter that was carried out, resulted in a wear of 16.4 g on the surface of the roller and 21.6 g on the studs for the variation of 3.6 mm diameter and 0.8 mm in stud height, determining a coating life time of 392.63 hours for the base case variant and increasing the useful life to 863.79 hours for the optimal design proposed.
