2011-4-29 · In other words, a balance between the striking force causing fraction of the particles and the material resistance is achieved at particle size around 30 nm. Obtaining nanoparticles of ZnO in this size (30 nm) is a remarkable result, maybe due to the use of the high-energy ball milling technique.

The relations between the milling periods with the iron mill scale particle size have been studied. Iron mill scale has been chosen for this research due to the nature of itself, as a by-product. From this research, the average optimum size for the final iron mill scale particle size intended to produce is at 300 μm. Raw iron mill scale received from the industries was in the form of chip ...

In the planetary ball mill, centrifugal and Coriolis forces permit grindings down to the submicron range. The result of grinding of alumina (Al 2 O 3) at 650 min-1 in the PM 100 is shown in Figure 5. The mean value of the particle size distribution is 200 nm after 1 hour of size reduction in water with 1 mm grinding balls; it is 100 nm after 4 ...
