Ball mill is the key equipment for grinding iron ore particles after crushing. The purpose is to achieve sufficient dissociation of useful minerals to achieve a better beneficiation effect. It has features like energy efficient, stable operation, long …
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.
