Fine grinding: How mill type affects particle shape ...

2017-9-1  To complement the laboratory data on shape, samples were taken from a plant-scale UG2 fine grinding circuit with a ball mill and IsaMill operating in series. This was to determine whether the findings relating to particle shape from the batch laboratory grinding data would be consistent with plant scale operations.

A Power Model For Fine Grinding HIGmills

2019-5-8  Fine grinding in stirred bead mills is becoming increasingly common in the mineral processing industry. Typically they are used as regrind mills in concentrator circuits where the reduced volume of high-grade ore justifies the high energy input, however they are now also being considered for some duties previously performed by ball mills (Capstick and Currie, 2012). Unlike conventional grinding mills (ball, SAG etc), fine grinding bead mills

ISAMILL FINE GRINDING TECHNOLOGY AND ITS

2017-12-21  IsaMill is a major development in grinding technology jointly invented by Mount Isa Mines of Australia and Netzsch Feinmahltecknik GmbH of Germany for ultra-fine and fine grinding duties in the minerals industry. The IsaMill was introduced by MIM over a period of 9 years, as there was no existing ultra-fine grinding technology that could be used or modified for use in the minerals industry. The IsaMill technology demonstrated its ability for very power efficient grinding to less than 10 micron. The major hurdles that required extensive investment in time and money were the high wear rates, characteristic of this type of technology, and the separation of media from the product. Other technologies use exotic materials in construction and screens for these purposes but they are not consistent with a low cost, large scale and reliable grinding technology. The result of MIM’s
