'Work Index' is to measuring energy in size reduction what the 'meter' is to measuring distance. It is a standard For example, a grinding circuit is processing 450 t/h (of dry feed) with a mill drawing 3,150 kW (at the pinion). The circuit feed Then WIo, the "Operating Work Index" of this circuit, is calculated as follows: W3 W4.
