STIRRED MILLING TECHNOLOGY Mill structure The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs mounted on a shaft. There are also stationary discs on the mill body positioned in between each
The stirred mills are charged with a media size of 10–12 mm and operated at a maximum tip speed of 3–8 m/s. The detritor mill, however, has a maximum tip speed of 11–12 m/s. Even though a finer ground product is obtained with higher speeds, a limit has to be imposed. This is to allow the separation of media and mineral particles at ...

Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented (Stehr, 1988). The year 1948 saw the successful application of Du Pont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of

Modeling of wet stirred media mill processes is challenging since it requires the simultaneous modeling of the complex multiphysics in the interactions between grinding media, the moving internal agitator elements, and the grinding fluid. In the present study, a multiphysics model of an HIG5 pilot vertical stirred media mill with a nominal power of 7.5 kW is developed. The model is based on a ...
A pilot-scale grinding technology of ceramic medium stirred mill was proposed in this study. Based on the specific productivity and grinding efficiency, the appropriate grinding parameters were ascertained as follows: material ball ratio of 0.7, ceramic ball medium size ratio (10 mm: 15 mm: 20 mm = 3:2:5), stirring speed of 110 rpm, grinding concentration of 50%, and medium filling rate of 90%.

mill [8,9], and the power of a centrifugal mill [10]. However, up to now, there has been little simulation research for stirred grinding media mill. In the stirred ball mill, there are some stirrers and the calculation of its consumed powder becomes more complicated to compare with the simpler kinetics of conventional tumbling ball mill [11,12].
Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear. Three different mill ...
