Ball milling experiments were done in a high energy planetary ball mill at a rotating speed of 300 rpm. To avoid the occurrence of any undesirable polluted phases, the ballmilling experiments were halted periodically (every ks) and then restarted when the temperature of the vial reached about 300 K.
The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ballmilling energy is not mature. The theoretical model of a ball mill was established for the first time to simulate the motion, collision process, energy transfer, and temperature change of small balls during the ballmilling process.
The milled powder of SPEX ball mill was 1000 times smaller in comparison with planetary for a ball milling period of 2 h. The size of the milled powder was <50 nm and 40 µm for SPEX and planetary ball mill, respectively. The average particle sizes are estimated around 25 nm and 15 µm for SPEX and planetary ball mill, respectively.

The planetary ball mill was operated at 600 rpm under ambient conditions (25 ± 1 °C). Reduction in particle size takes place in planetary ball mill through counter rotation of the sun wheel and the milling jar. This results in rotational motion of the zirconium balls in the milling jar leading to the development of Coriolis forces inside it.
