Stirred media mill decreased bauxite d50 size from 780 to 5 µm in 3 min. But, the ball mill has reduced to 455 µm at the end of the same grinding period. In addition, the energy consumed by the ball mill for similar fineness (5 µm) was approximately 300 kWh/t energy, whereas the stirred media mill consumes approximately 174 kWh/t energy. As ...
