The grinding media are the key factors for effective grinding and thus for successful flotation. In this study, ceramic ball (CB) and cast iron ball (CIB), two representative grinding media, were chosen to investigate the effects and mechanisms of grinding media on the flotation behavior of scheelite.
The flotation behavior of beryl and spodumene (typical silicate minerals) was studied at wet-grinding conditions with different grinding mediums, with dodecylamine or sodium oleate as the collector. The mechanism of potential influence of the grinding medium to the flotation behavior was investigated through measuring zeta potential of pure minerals, micro scanning by X-ray photoelectron ...

Besides, several studies on the effect of wheel speed on the grinding mechanism using a single grain have been reported. Zhao et al. conducted ultra-high speed (i.e. 720 m/s) single grain tests using rifle as the accelerator and charger to study the speed effect on the material removal mechanism. The research indicated that the material flowed ...

The service life of the bearing is greatly reduced. At the same time, it will be difficult to dismantle it from the grinding roller due to over tightening when the bearing is damaged, which will bring further difficulties to the vertical grinding mill. If it is too loose, the gap between the grinding tracks will increase, and the grinding roller & the bearing cannot be closely connected.
Such effect of fluid and grinding speed on radial wear would be justified in accordance with the wheel wear mechanism in the subsequent section. G-ratio has varied from 64 to 637 in the present study, which is quite similar to an earlier study of titanium …
