mills equalling the ball mill efficiency could lie in the region of F80 = 3 to 4mm. The vertical gravity induced mill has a recommended efficiency factor to 0.80 (i.e 20% energy benefit) or higher when feeding the Vertimill with coarse feed F80 = 2.6mm (Hounde 2019). Ballantyne (2021) determined that the scaleup could

Varied types/geometries of stirred mills have been produced by different manufacturers, and the comparison task has been accomplished for some of the technologies, i.e., Tower mill vs IsaMill.

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 between …

Mathematical models are presented which describe the power consumption in agitated ball mills in absence of grinding beads. In addition, tests with grinding beads filling were also performed, leading to scale-up guidelines with respect to power consumption. Finally, the influence of size and material of grinding beads was investigated.
