comparison to each technology. Both the fluidized stirred mills, the Horizontal Stirred Mill (IsaMill) and the Vertical Stirred Mill (VRMTM) have a scaleup of factor of 1:1 when applied to test work (Larson M 2011, Paz 2019, Paz 2021, Harbort 2016, Gurnett 2019). The reason that the scaleup is 1:1 is that the same feed

Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 20 microns. …
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 …
Breakage function curves obtained from a Bond ball mill and a vertical stirred mill for an aggregate sample. The specific selection function, S i E, was also estimated for the same aggregate feed sample by using the Bond ball mill and a vertical stirred mill in order to determine if a relationship between the obtained results could be …
2. Bond ball mill versus vertical shaft stirred mill 2.1. Experimental work A standard Bond ball mill and a laboratory pin type vertical shaft stirred mill (Fig. 1) were used for the comparative tests. Both mills are installed at JKMRC pilot plant. The stirred mill test rig consists of a 3-phase motor/gearbox mounted on a frame.

The attritor ball mill, also known as stirred ball mill, is a kind of vertical ball mill. It can be divided into dry type and wet type, suitable for grinding a variety of materials, such as industrial ceramics, fireproof materials, silicate materials, metal powder, ores, etc. It is equipped with an agitation system inside the grinding cylinder.
Sinnott, Cleary and Morrison [7], [19] provide an overview into how DEM compliments the vertical stirred mill process by comparing a pin mill with a tower mill. More recently, Daraio et al. [20] explored the effect of impeller length for a pin attritor design based on previous experimental study.
Vertical stirred mills have stationary walls [24,51]. The tension energy for comminution comes from a spindle with perforated discs that rotate quickly in the centre of the system. The perforations of the discs are designed to direct the slurry toward the discharge end. ... Stirred ball mills, in contrast, feature a high-speed rotor and an ...
This was developed into the first 'stirred ball mill' by Klein and Szegvari in 1928 [20]. This prototype was refined into the Attritor mill, a low tip speed (3–5 m/s [21]) vertical pin mill which has been produced in various forms by Union Process since 1946 [19]. Several other stirred media mill designs have been developed over the ...
