  • Simulation of charge motion in ball mills. Part 1

    A numerical tool known as the discrete element method (DEM) is used to study the motion of the ball charge in ball mills. In particular, the motion of individual balls in the ball charge is simulated. An interesting aspect of this simulation is that it yields the frequency distribution of ball collisions as a function of collision energy.

    Many unobservable facts about charge motion are revealed by this simulation approach: It is shown that larger balls segregate to the center at high speeds and to the shell at lower speeds. The frequency of collisions in a 4.75 m diameter mill mostly lie within one joule. The friction between the ball charge and the mill shell can increase the

    Simulation of charge motion can be used to identify such potential problems (Powell et al., 2011), and acoustic monitoring can give indication of where ball impact is occurring (Pax, 2012). At relatively low speeds, or with smooth liners, the medium tends to roll down to the toe of the mill and essentially abrasive comminution occurs.

  • How Ball Mills Lifter Bar Affects Charge Motion

    The action of lifter bars is best understood by following the motion of ball charge inside the mill. There are two well-known modes in which the ball charge moves inside the mill: cascading and cataracting. The cascading motion of ball charge forms a compressive zone inside the mill where particles may break under slow compression.
