Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls generally Zirconia ZrO 2 or steel balls, acting as grinding media and rotating shell to create centrifugal force. In this process, graphite precursor was breakdown by randomly striking with grinding media in the rotating shell to create shear and compression force
Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by both impact and abrasion.
The ball milling process is carried out for approximately 100150 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 high-energy ball milling, formation of ceramic nano-reinforcement by in situ
