processes inside planetary ball mills are complex and strongly depend on the processed material and synthesis and, thus, the optimum milling conditions have to be assessed for each individual system. the present review focuses on the insight into several parameters like properties of grinding balls, the filling ratio or revolution speed.

ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. with this motion, the particles in between the media and chamber walls are reduced in size by
