A Method of Calculating Autogenous/Semi Autogenous

Since the days of mandatory high cost pilot plant testing in 6 ft 215 2 ft SAG mills autogenous griding/semi autogenous grinding (AG/SAG), mill specific energy is now calculated by various empirical formulae and pilot testing carried out in small laboratory mills. Barratt (1989) described a method using Bond Indices than adding a single factor of 1.25 to arrive at the AG/SAG specific energy. In

OverviewGrinding machinesGrinding lawsTypes of grinding millsSee alsoExternal links

In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy for this reason, an experimental method to measure the energy used locally during milling with different machines was recently proposed.
