ball mill operation is often regarded as something of a mystery for several reasons. ball milling is not an art its just physics. 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.
usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. figure shows that there is no linear relation between
