The first problem will ball mills is that we cannot see what is occurring in the millThe other problem is that many of the independent variables are non-linear or have paradoxical effects on the end resultsIn ball milling of dry solids the main independent variables are mill diameter mill speed media size solids loading and residence time.
The ratio of rotational speed to revolutional speed is for example from about 2 to about 8In the planetary ball mills in the related art for example the revolutional speed is 2000 rpm and the rotational speed is 60 rpm; thus the rotational speed has been by far lower than the revolutional speed.
