Stirred Milling Technology – A New Concept in Fine

2019-5-8  High power intensity and energy efficiency In stirred media grinding, the energy intensity (kW/m³) is very high versus tumbling mills. In the HIGmill the power intensity (installed) is typically 180 to330 kW/m³. This means a very “packed” process: i.e., high throughput and/or high SGE in a small unit.
