milling in a planetary ball mill on its parameters. Kakuk et al. (2009) modelled the milling process in a planetary ball mill and found a relationship between the angular velocity of the sundisk and the vials, and the geometrical parameters of the mill. Farahbakhsh et al. (2011) investigated the mechanical alloying of

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

Awasthi et al[98] reported the formation of carbon in different nanoparticle forms by ball-milling of graphitic carbon. Ball-milling of graphite was carried out in attritor ball mill at room temperature in hexane medium for different times i.e. 24, 48 and. The self-coagulated carbon agglomerates were obtained in the case of 24 and BMC samples.

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
