Ultra-fine grinding must be carried out using specialised equipment, specifically stirred media mills. Due to geometric limitations, tumbling ball mills have a small energy intensity, limited by the number of revolutions at which the grinding media is centrifuged in the mill wall ( Celep et al., 2011 ).
