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

Ball milling works on the principle of impact and attrition; size reduction results from impact as the balls drop from near the top of the shell. A ball mill is made up of a hollow cylindrical shell rotating about its axis. The axis may be either horizontal or at an acute angle to the horizontal. The shell is partially filled with balls whose grinding by action of balls, made of steel (chrome

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc., as well as for ore dressing of ferrous and non-ferrous metals. The ball mill can grind ores and other materials, wet or dry. There are two kinds of ball mills according to their ways of
