The authors equipped the laboratory-scale planetary ball mill (Retsch PM400) with a rig that allows moving the camera along the rotation of the mill (Fig. 1), recording the motion of the media inside the grinding chamber. In the system, the high-speed camera Mako G40–250 fps is fixed on the sun wheel rotating with the pot (Fig. 1).

Although the ball-to-powder ratio and ball milling time each have around a 20–25% impact on the grain size reduction rate, ball milling speed has almost a 48% impact. The powders were characterised for grain size using an x-ray diffraction technique, and the powder morphology was studied using a scanning electron microscope.

The major differences between conventional ball milling and high-energy ball milling (HEBM) are: (1) In the HEBM process the impact energy is around 1,000 times higher than in the conventional ball milling process.

The impact energy of the milling balls in the normal direction attains a value of up to 40 times higher than that due to gravitational acceleration. Hence, the planetary ball mill can be used for high-speed milling. Schematic view of motion of the ball and powder mixture.

The working principle of a ball mill is based on the impact and attrition between the balls and the grinding media. As the mill rotates, the grinding media (usually steel or ceramic balls) are lifted to a certain height and then allowed to fall freely, causing the materials to be reduced in size by the impact and abrasive forces generated ...

Milling devices used: (a) knife mill, (b) impact mill (IM), (c) rotary ball mill (RBM), (d) stirred ball mill (SBM), and (e) vibratory ball mill (VBM). Before final comminution in the different ball mills, all samples were re-dried to a moisture content of about 3%, as measured by weight loss after oven-drying for 2 h at 135 °C.

This means that during one rotation of the sun wheel, the grinding jar rotates twice in the opposite direction. This speed ratio is very common for Planetary Ball Mills in general. Planetary ball mills with higher energy input and a speed ratio of 1:-2.5 or even 1:-3 are mainly used for mechanochemical applications.
