[email protected]Once you know the ideal speed of rotation for your mill jars you will need to design your mill around this critical parameter. With most ball mill designs you have two areas of speed reduction to tweak from the motor drive shaft to the drive pulley and from the roller bar to the milling jar.

### Variables in Ball Mill Operation Paul O Abbe174;

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.
