Discrete element simulation of particle motion in ball ...

Jul 15, 2018 · Discrete element method. The DEM is a numerical method to address the kinematic and mechanical behaviour of complex granular systems involving many discrete units with certain shapes and masses. It has been widely used in ball mills [18,36] to determine the particles behaviour and the torque and energy of ball mills in different working ...

Analysis of Power Draw in Ball Mills by the Discrete ...

Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously simulated with a ...

Furthermore, the discrete element method (DEM) simulation showed that the wear behavior on the upper surface is higher than that on the side surface of the lifter. The DEM simulation with Archard wear model is an effective tool to investigate the wear distribution on the lifter, which is in good consistent with the wear behavior measured by the ...
