SAG Mill Grinding Circuit Design - 911metallurgist

Semi Autogenous Design FactorsSag Mill Operation ExampleProcess Plant DescriptionSag Mill Design and SpecificationOperating Problems Since CommissioningDesign Changes and Future Operating StrategiesThe 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...

Grinding Circuit - an overview | ScienceDirect Topics

In SAG mill operation, the grinding rate passes through a minimum at a “critical size” (Chapter 5), which represents material too large to be broken by the steel grinding media, but has a low self-breakage rate. If the critical size material, typically 25–50 mm, is accumulated the mill energy efficiency will deteriorate, and the mill feed ...
