Comparison of energy efficiency between ball mills and stirred mills …

The work using a vertical shaft stirred mill compared with Bond ball mill, both operated in closed circuit with a classifier, demonstrated a clear trend that on average 30% energy saving can be expected by using the stirred mill to replace ball mill for coarse grinding from a top particle size 3.35 mm to P 80 less than 100 μm.
