Effect of Grinding Media Shapes on Breakage …

In the present study, the effect of grinding media shape on breakage parameters was investigated. Balls and cylpebs were used as the grinding media. It was observed that the grinding of quartz obeyed first‐order breakage kinetics in the case of balls and cylpebs. Higher breakage rates were noted with cylpebs than with balls. Furthermore, it was found that the primary breakage distribution ...

Waterfall mode motion of grinding media

Waterfall mode motion of grinding media — the mode motion of grinding balls carried out at a drum rotation frequency of 78-88% of the critical drum rotation speed. Waterfall mode motion provides the grinding balls transition from circular to parabolic trajectory. Material crushing occurs mainly due to the falling grinding balls impact and partially due to crushing and abrasion.
