Ball Millingan overview ScienceDirect Topics
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
