Variables in Ball Mill Operation | Paul O. Abbe®

The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results. In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time.
