2 ABSTRACT Discrete Element Method simulation of charge motion in ball, SAG and autogenous mills has become a standard for lifter design, power draft evaluation, etc.

An innovative jar shape for the planetary ball mill is proposed and characterized through simulations and experiments. • Increased high velocity collisions along impact axis enhance comminution with respect to the conventional jar.

In this paper, we examine the axial transport in dry ball mills. This requires simulation of the entire mill and the full volume of the charge for significant periods of time (thousands of revolutions). We use a simple model for grate discharge that allows prediction of the time varying axial distribution of different particle sizes within a discharging ball mill…

Development of a 3-Dimensional Version of the Millsoft Simulation Software Today's high capacity semiautogenous grinding (SAG) mills expend vast amounts of energy, and in doing so consume tons of steel balls, as well as shell liners, while processing ore. A considerable amount of this energy is expended on unwanted ball strikes on the mill …

A number of simulations corresponding to differing operating conditions for the test ball mill have been carried out. These are summarized in Table 2. With the predicted results, the effect of the following operating conditions on the mill ...

Many simulation tools exist to obtain the necessary information about media trajectories. Data are used to avoid the risk of liner and ball damage by projecting balls directly on the shell liner. Figure 3b illustrates this issue. Obviously, a good liner design and the right operating conditions such as mill speed or balls filling degree, should limit the risk of …
