Energy requirements for crushing and HPGR options can now be determined in addition to AG/SAG mills, and with Mic, ball mills. The results from conducting the SMC Test are used to determine the socalled dropweight index (DWi) which is a measure of the strength of the rock.

Autogenous and SemiAutogenous Mills

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod millball circuit. All of the above contributes to

SAG Mill Grinding Circuit Design 911metallurgist

Sag Mill Operation ExampleThe design of large mills has become increasingly more complicated as the size has increased and there is little doubt that without sophisticated design procedures such as the use of the Finite Element method the required factors of safety would make large mills prohibitively expensive.In the past the design of small mills, up to +/ 2,5 metres diameter, was carried out using empirical formulae with relatively large factors of safety. As the diameter and length of mills increased several crit
