Grinding and Dispersing Nanoparticles
The average particle size that can be achieved quickly in a bead mill is about 1/1000 the size of the grinding media. Figure 1 illustrates this point. In this experiment we processed limestone using two different media sizes: 0.4-0.6 mm zirconia-silica grinding media (SAZ) and 1.6–2.5 mm SAZ.
