Therefore, the ball milling treatment was used to remove sharp corners and smooth the surface of the precursor powder particles. Ball milling process was conducted in a planetary ball milling machine (QM-3SP04, Nanjing University Instrument Factory) equipped with four nylon ball mill tanks with an internal volume of 50 mL.

For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load ratios and circulating load tonnage on tons/day or tons/hour.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

As the mill rotates the ball charge will induce a load on the mill structure that the driving torque has to overcome. To numerically calculate the torque that the mill is exposed to, a numerical interface is created for the rigid structure of the mill. Since the structure is rigid it can be considered as a boundary condition for the ball charge.
