    the Ball mill, the median size of the grinded product is 345 µm; in the stirred mill, it is 430 µm. Similarly, for a 21.4 kWh/t energy consumption, the median size of the product is 200 μm in the ball mill; and, 292 µm in stirred mill. Therefore, the Bond mill is more advantageous than the stirred mill regarding energy consumption.
