We see that, although the powder used as input was first calibrated between 0.8 and 1.0 mm, after 1.5 min of milling the particles are already broadly distributed over nearly 3 orders of magnitude. While milling, the main peak of the distribution shift from 100 μm to 2 μm. Fig. 3 shows SEM images of the powder for two values of milling ...

Once the application requirements are clear, a suitable mill can be selected. To facilitate this process, Retsch displays the strength and efficiency of each ball mill model in a spider-net diagram, see Figure 3. A planetary ball mill, for example, offers a big jar volume compared to a mixer mill and shows a high value on this diagonal.

where E ball is the kinetic energy of a generic marble, m ball and v ball its mass and speed. The higher E ball, the finer the ultimate particle dimension [].. Independently of the mill's power, when crushing coarser particles, the reduction rate is nearly linear at first. As size reduction progresses, the rate asymptotically decreases and eventually drops to zero [].

Wet Media Milling. Particles are dispersed in a liquid slurry and media milled to obtain a uniform particle size distribution. The shearing forces (tearing apart), impacting (crushing by outside forces), and attrition (tearing and crushing each other apart) create particle distributions in the nanometer or sub-micron ranges.

The ball milling process is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills.
