SAG Grinding VS Crushing Grinding Circuits

Long ago, when cone crushers arrived on the market, autogenous grinding was simultaneously becoming quite fashionable in the mining industry. As part of our study, we queried many of the major mining companies about their thoughts regarding the use of autogenous grinding circuits versus conventional crushing-grinding circuits.Secondary & Tertiary Crushing Circuits,This circuit is employed where either the tonnage or the work index of the ore is high enough to require that the crushing be done in stages. Again the ore will come from a Primary crusher and be scalped.Crushing and Grinding Circuit Design - PDF Free,Approximately $9M and $120M is expended on the comminution circuit (crushing, stockpiling and grinding) representing 35% and 50% of plant capital cost for the 1 Mt/a and 20 Mt/a plants, respectively. Comminution costs include power, grinding media and maintenance materials.
