Effect of Ball Diameter, or Rod Diameter Variation The first relationship to be considered is the effect of the variation of the ball diameter, or rod diameter, upon the size distribution obtained. In Fig. 6.1 are shown typical size frequency curves obtained by ball milling these curves being deduced from the data of Coghill and Devaney.

A ball mill, a type of grinder, is a cylindrical device used in grinding or mixing materials like ores, chemicals, ceramic raw materials and 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.

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency a Mill Geometry and Speed Bond 1954 observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different

Effect of mill type on the size reduction and phase transformation of gamma alumina. Shearinduced phase transformation is observed in planetary ball mill. a high impact energy mill has no effect on initiating phase change in Al 2 O 3. It is more favourable as it promotes grain size refinement and an increase in surface area.
