The effect of ball size distribution on power draw, charge ...

The grinding process within a tumbling ball mill includes coarse and fine grinding, which are mainly provided by big balls and small balls separately. A suitably chosen ball size distribution could affect not only the output, but also the quality of product (Zhang et al., 2014). Many researchers have

The Evolution of Grinding Mill Power Models | SpringerLink

In the discrete element simulation of tumbling mills, the energy expended in the collisions between ball to ball and ball to mill shell is summed over one or two full revolutions of the mill to predict net power draw. Correspondingly, in the case of SAG mills, the collision pair between balls, ore particles, mill shell, and liner is summed.
