Assessing the Effects of Material Properties on Load Behavior in Dry Ball Mills Using DEM

Understanding how the mill load behaves is crucial for enhancing ball effectiveness. This study aimed to create a discrete element method (DEM) model simulate motion charge in mills and analyze simulation material properties affected behavior. The steel balls were modelled as collection of distinct particles, each which was subject Newton’s laws tracked Lagrangian manner. Hertzian contact law used describe inter-particle collisions. Then, this numerical coded using open-source C++ program LAMMPS Improved General Granular Heat Transfer Simulation (LIGGGHTS) mimic laboratory pilot-scale mills. positions measured from DEM simulations compared published experimental data empirical models comparable experiments validate findings. angular shoulder position ranged between 137° 154° range Young’s modulus 0.5 1000 MN/mm2. Angular toe had variation less than 10% data. outcomes demonstrated significant relationship characteristics such Young's simulation. preliminary can be choosing appropriate parameters both with coupled CFD–DEM multiphase simulations. assessment concluded that affect behavior computer
