conventional crushing and grinding circuits (crusher-rod-ball mill or crusher-ball mill). By the 1970s, the application of conventional tended to be limited to relatively low capacities. circuits The majority of modern grinding circuits include a SAG mill, a ball mill and/or a combination thereof. The use of Bond

--- the range of crushing is the range of basic law of Kick. The slope of cumulative curve varies from m = 0 to m 0.1. the range of coarse grinding is the range of Bond's theory, (rn = — 0.5) and the range of fine grinding is the range of Rittinger's theory ( m = — 1.0 ). - the range of fine grinding from m = —1 to — 3,

Jan 01, 1989 This enables a more objec- tive identification of the energy required for grinding in the case when, for a certain grinding-product size, we do not dispose of the appropriate work-index value established by experiments. 46 REFERENCES Bond, F.C., 1961.
