Towards a Better Understanding of Stirred Milling

As a case in point, the VERTIMILL grinding mill has been cited in a couple of papers (Nesset et al., 2006; Mazzinghy et al., 2012) as being some 35% to 40% more efficient than ball mills for fine grinding with the same ore and size distribution.

Fine Grinding Technology for Mines and Concentrating

Both coarse and fine grinding applications were investigated. The study examined seven ore samples with feed sizes ranging from 3.35 mm to 150 microns. The vertical stirred mill showed energy savings of 25%, 37%, and 27% relative to a ball mill in coarse grinding duty. For desired particle sizes less than 40 microns, horizontal stirred mills ...

Stirred Mill an overview ScienceDirect Topics

The attrition mill agitator rotates at speeds ranging from 60 rpm for production units to 300 rpm for laboratory units and uses media that range from 3 to 6 mm while ball mills use large grinding media, usually 12 mm or larger, and run at low rotational speeds of 10–50 rpm. Power input to attrition mills is used to agitate the medium, not to rotate or vibrate heavy drums.

Using stirred media mills in ore grinding Technologie

May 24, 2021 In stirred media milling, a smaller grinding media size compared to a conventional ball mill makes high-speed movement possible, thus higher force on the ore particles trapped in media is applied. This is significant since as the particle size becomes smaller, the force needed to break the particles increases.
