sag mill feed size

When thefeed sizeof aSAG millbecomes coarser, i.e. α r increases, the energy required to break the ore increases, i.e. φ r and φ f increases (Morrell et al., 1996; Morrell and Valery, 2001 ...

    AG/SAG millscan accomplish the samesizereduction work as two or three stages of crushing and screening, a rodmill, and some or all of the work of a ballmill. Because of the range ofmillsizes available, AG/SAGmilling can often be accomplished with fewer lines than in a conventional rodmill/ballmill…
