• ### Analysis Of Power Draw In Ball Mills By The Discrete

The motion of the charge is rigorously simulated with a numerical technique known as Discrete Element Method DEM. In this technique, the coordinates and velocities of each individual ball are computed from a knowledge of forces arising when balls collide with each other and with mill shell and lifter walls. First, simulation results on a wide ...

• ### Dem Simulation Of Mill Charge In 3D Via Gpu Computing

Discrete Element Method simulation of charge motion in ball, SAG and autogenous mills has become a standard for lifter design, power draft evaluation, etc. Both two-dimensional and three-dimensional codes are being used. The two-dimensional code dominates the user market since the code completes a simulation in one or two hours.

• ### 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 ...
