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.
