Cost optimization of stirred ball mill grinding ...

An example is the selection of rotor speed. In general, lower speeds result in lower energy consumption per ton of material ground but at the cost of reduced mill capacity per unit volume. Because stirred ball mills have a high capital cost per unit volume the trade off between energy consumption and capacity becomes critical.
