The effect of grinding media J performance on milling and
efficiency of the manufacturing process. Wet grinding and ultrafine wet grinding in stirred media mills are now a possible cost-effective production step for the processing of industrial minerals and precious metals. The generation of smaller particle sizes (down to micrometer scale), adjusted to specific particle size distri-
Stirred Milling Technology – A New Concept in Fine Grinding
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.
Analysis of energy requirements in stirred media mills
Abstract. Vertically stirred media mills represent an important tool for the comminution of a range of industrial minerals. In this work, calcium carbonate is ground to size ranges below 2 μm in an Imerys stirred media mill. The role of grinding media on the efficiency is considered, and with the use of a novel, rod shaped grinding media, significant energy savings in ultrafine wet grinding …

Nanoparticle Production with Stirred‐Media Mills
Aug 16, 2010 · Nanoparticles can be produced by wet grinding in stirred‐media mills. In the lower nanometer range a true grinding limit exists, where the transferred energy from the grinding media is no longer sufficient to induce further breakage of the particles even after stressing events with high stress energies. Variations in process conditions lead to the conclusion that the grinding …
