The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.

The aim of this study is to assess pullulan as a novel steric stabilizer during the wet-stirred media milling (WSMM) of griseofulvin, a model poorly water-soluble drug, and as a film-former in the ...
Abstract Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. In the context of the mining industry, interest in stirred milling technologies has grown over the last 20 years where the typical observation reported in the literatu...

Stirred milling is a grinding tool that is used extensively for mineral liberation, in order to achieve successful downstream processing such as flotation or leaching. The focus of this research is to understand the effect of different operating parameters on particle breakage mechanism. Operating parameters could be summarized as stress intensity on the particles which are varied by changing ...

system that enables slurry to exit the mill but prevents the grinding media from leaving the mill (Enderle et all, 1997). Since this time, the ISAMILL® technology has been implemented at several mining operations and undergone further development. The latest development is a 2.6 MW, 10 m3 unit installed
media at site, this higher SG media aids the retention of finer media and contributes to maximising grinding effi-ciency. The performance of SG 4.0 vs SG 4.5 media resulted in a 5-10% loss in SGE efficiency in the first month of opera-tion, however the media retention in the mill was greatly increased such that the loss of fine ~0.8mm media is only
Superfine ground calcium carbonate (GCC) produced by carbonate minerals is a widely used inorganic powder material. In order to get a finer GCC powder with narrow distribution span, the effect of rotational speed and media density on ground GCC were studied by dry grinding GCC in a planetary ball mill under different rotational speed and various media density.
The mining industry will be faced with new challenges as the need to develop lower grade ore deposits expands to meet the rising demand for raw resources. Low-grade deposits require a substantially increased tonnage to achieve adequate metal production and have caused the consumption of energy in mining practices such as comminution to rise dramatically. If improvements could be made in the ...
Samples were taken from well-mixed batch. Glass beads ( 2.5 g/cc) were used as mill media for grinding limestone, except for a few instances when steel media was used. In order to observe the flow pattern of media/pulp, a transparent glass cylindrical tank was used. Otherwise, steel grinding …
