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 .

The ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 1–1.5 times the shell diameter (figure 8.11).the feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
The impact energy of the milling balls in the normal direction attains a value of up to 40 times higher than that due to gravitational acceleration. hence, the planetary ball mill can be used for high-speed milling. schematic view of motion of the ball and powder mixture.
