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 ...

How Ball Mills Lifter Bar Affects Charge Motion

The power draw of a mill is often considered as the basis for comparison between the performance of different mills. Here, the power draw of a real mill is estimated from the two-dimensional torque data as calculated in each simulation. The mill is considered as individual slices in which the ball-charge motion is confined to the radial ...

A Review of Advanced Ball Mill Modelling

A major advance in the modeling of ball mills became possible through the development of the discrete element method. DEM provides a numerical procedure for solving Newton's second law with an appropriate contact relationship that can be applied to describe the motion of each grinding medium contained in the mill charge to predict element position, velocity and forces of interaction over time.
