2019年10月31日 In this study, we investigate the effect of the ball size in a high-energy ball mill on the comminution rate and particle size reduction. High-energy ball milling at 2000 rpm produces ultrafine talc particles with a surface
More2024年9月29日 In a ball mill with constant rotation speed and ball fill rate, the grinding efficiency is primarily influenced by the ball size distribution and placement. As the mill operates, the balls tend to distribute themselves based on a specific pattern, with larger balls focusing on coarse grinding near the feed end and smaller balls towards the discharge end for fine grinding.
