· Fine grinding is a relatively new area and considers grinding below 30 μm down to around 10 μm. Below 10 μm, the term “very fine grinding” can be used. The energy consumption in ball milling rises sharply for grinding products below 75 μm and below 30 μm grinding using ball mills becomes uneconomical.
