Nowadays computer simulations have been shown to be powerful tools to understand the performance of systems where we have mathematical models that can capture the physics of the problem. In this paper we attempt to simulate the behavior of the particles that move inside a largescale mine mill, specifically through the grates and the discharge ducts of the material, when small changes are made
