Ball Mill an overview ScienceDirect Topics
The ball milling process is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills.In this experiment, a horizontal stirring 1 L high-energy ball mill (1 L capacity, HCX-1) and a 2 L high-energy ball mill (2 L capacity, HCX-2) produced by Kunming Haichuangxing Company were used for comparative experiments.
