Vertical stirred mill scale-up and simulation: Model …
Stirred mills were introduced to produce fine and ultrafine particles from coarse feeds at lower energy consumption [31]. It is a 30–40% more energy-efficient advanced grinding mill than the ball mill, especially for grinding below 100 μm [32-36]. The breakage mechanism in stirred mills differs from conventional mills [37].
