vertimill for fine grinding - kinderthuisverplegingkempen.be

Dec 18, 2013· Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget.

Stirred mills impart motion to the media by an internal impeller keeping the shell stationary (Sinnott et al., 2006). Steel balls as grinding media are also usually employed in stirred mills. A class of vertical stirred mills is the Vertimill, which was designed for fine and ultrafine grinding operations (Jones and Holmberg, 1996).
