Stirred Ball Mill Ore Grinding
Popularity of Stirred Mills and HPGR
Regarding stirred mills, the two issues you haven't touched on are they can be a pain in the butt to do maintenance on (you have to dump the mill contents of the floor which you don't do with a tumbling mill) and sometimes they have issues with the top size of material that comes from upstream stages (you need to match the media size in a stirred mill its feed top size).

Both coarse and fine grinding appliions were investigated. The study examined seven ore samples with feed sizes ranging from 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 Media Millvertical
Stirred bead mills also known as stirred media mills find appliion in a number of industries where they are used for fine grinding of particulates or fine dispersion of agglomerates 1 In the minerals industries fine grinding in stirred mills is becoming increasingly important since available ore bodies are increasingly finegrained and.

Mr Rule said stirred mill grinding technology had been well proven for decades in industrial mineral appliions such as in the opacifiers, fillers, ceramics, paint and pharmaceutical industries. "We commend STM for translating this technology to mineral processing, offering miners an energyefficient, low footprint alternative to highintensity ball milling," Mr Rule said.
The Ultrafine Grinding Mechanism of Inorganic Powders in ...
The grinding by a stirred ball mill to submicron range has been achieved commercially in many cases. A series of grinding experiments using a vertical stirred grinding media mill and inorganic powders such as calcite, pyrophyllite and talc as test samples were carried out to clarify the grinding mechanism of the stirred grinding media mill.
THE EFFECT OF GRINDING MEDIA PERFORMANCE ON WET MILLING .
This paper aimed to investigate the effects of monosized (, and mm) and bimodal ( mm) media size grinding design on wet grinding of calcite (CaCO 3, d 50 = µm) powders to produce submicron particles, and it was performed in a labscale (750 ml) stirred media mill. The effects of different amounts of finer media (25 wt.%, 50 wt.% and 75 wt.%) and finer to coarser grinding ...

Vertimill VS Ball Mill
If we instead focus on wet grinding, we should differentiate between stirred media grinding, which can be both vertical and horizontal, and tumbling mills with manufactured grinding bodies. A continuous gratedischarge tumbling mill with grinding balls does seldom have ball size below 20 mm since you then will have unacceptable media losses or problem with grate throughput.
