Jul 02, 2021 A ball mill is a type of grinder that is typically used to grind materials into extremely fine powders. The cylindrical shell of a ball mill is filled with big cylindrical pellets of some substance. The internal cascading effect of these balls and the material being ground within generates a fine powder when the shell is spun around its axis.

balls, meaning that the ball size distribution had some effect on crushing and grinding Zhang et al., 2014. However, the horizontal planetary ball mill is different than the tumbling ball mill in many aspects. Djordjevic 2005 studied the influence of ball charge size distribution on the net-power draw of tumbling mill based on DEM modeling.
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.
