Stirred media mills are used in numerous industries because of their high energy efficiency, fine and ultrafine grinding ability, and reduced contamination. In view of their growing importance, basic research on power characteristics of stirred media mills has been carried out [1,2]. In this research, the torque required to rotate impellers ...

To address this, stirred milling technology has been adopted. Table 1 shows a list of stirred media mills currently available in the market for mineral processing. Since the introduction of stirred media mills in 1953 (Shibayam and Mori, 1999), the number of installed units has continued to grow (Kalra, 1999, Jankovic, 2003, Rule et al., 2008).

The wet milling process in stirred media mills is applied by various industries for the production of fine particles, for example, pharmaceutics, inks or ceramics [1]. The minerals industry has also adopted horizontal stirred media mills [2], such as the IsaMillTM, to meet the demand for particles in the lower micrometer range [3].
