2.2. Grinding Test. In this paper, the wet ball milling process was used in the laboratory ball milling test. Before grinding, the ball mill was kept idle for 10 minutes and then washed together with the grinding media. Three types of ores were crushed and separated by a jaw crusher, and the ground particle size of -2 mm was selected.

Consequently, they have limitations in exploring the behaviour of grinding media and particles inside the mill. Apart from measuring external response signal, instrumented ball has been used to mimic the behavior of grinding ball inside ball mill. Dunn and Martin (1978) used accelerometers to detect the maximum impact force of …
But, the ball mill has reduced to 455 µm at the end of the same grinding period. In addition, the energy consumed by the ball mill for similar fineness (5 µm) was …
As such, the planetary ball mill has been widely used in various areas such as in the preparation of ultrafine powder, mechanochemical process, and mechanical alloying because of its high grinding ability and energy utilization ratio [1], [2].
The minimum achievable grain size and extent of alloying depend on a number of parameters i.e., type of high-energy ball mill, milling container, ball-to-powder weight ratio, milling speed, grinding medium, extent of filling of the vial, milling atmosphere, process controlling agents, milling temperature, type of material being milled etc. …
