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

Chromium levels in grinding media varies depending on application, mill parameters, down stream processes but most importantly cost considerations. This can range from as low a 2% for chill cast material to as high as 25% in some specialized cases but generally falls in the 5 to 18% Cr range which can be heat treated to high hardness …

The IsaMill™, as shown in Figure 8.15, is a horizontal stirred mill consisting of a series of 7–8 rotating grinding disks mounted on a cantilevered shaft that is driven through a motor and gearbox. The disks operate at tip speeds of 21–23 m/s, resulting in energy intensities of up to 300 kW/m 3.The mill is filled with suitable grinding media, and the space …
Several types of the grinding media have been used in stirred mills. These include, but are not limited to, glass balls, ceramic balls, steel balls, zirconium balls, and river sand. He et al. [8] found that the severe wear of glass balls during grinding indicated that they were unsuitable and uneconomical as grinding media.
