2) Ball milling – a ball mill with a diameter of2.44 meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions, efficiency factors (Rowland and Kjos, 1978) have to be used in conjunction with equation 1.

Theseball millsare often called planetaryball mills. The rotating drums are not usually detachable -- the material is poured into the top and the cap is replaced, like a kitchen blender. Like allball mills, the speed andball sizehave an effect on how the verticalball millworks.

The first problem willball millsis that we cannot see what is occurring in themill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results. Inballmilling of dry solids the main independent variables aremilldiameter,millspeed, mediasize, solids loading and residence time.
