Get Price### energy use of fine grinding in mineral processing

where w is the specific grinding energy (kwh/t), w i is the bond ball mill work index (kwh/t), f80 is the feed 80 pct passing size (μm), and p80 is the product 80 pct passing size (μm). it can be seen that in the regime in which the bond equation is valid, energy use increases exponentially as product size decreases with constant feed size
