ball consumption in iron ore ball milling
Ball Mills - 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 ...
