摘要：

Liner ripple height and rotational rate are two important parameters which will influence the grinding efficiency of ball mill. In order to choose them reasonably, the dynamics equation of grinding media is established. Then the discrete element model of ball mill with waveform liner is built. The correctness of the established model was verified by comparing it with the experimental data in the literature [16]. The influences of liner ripple height and rotational rate on the collisions number and useful power as well as impact force are analyzed. The results show that with the increase of rotation rate and corrugation height, the number of collisions between steel balls and ores, impact force and useful power all show a trend of first increasing and then decreasing, while the number of collisions between steel balls shows a trend of first decreasing and then increasing, the best rotational rate is between 70% and 90%, and the best corrugation height is between 100mm and 140mm. The results of this paper can provide some reference for the optimization of ball mill parameters. © 2023, Politechnica University of Bucharest. All rights reserved.
