SAG Mill Grinding Circuit Design
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.

Characteristics of open- and closed-circuit grinding systems
Apr 15, 2004· The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closed-circuit is about 5% higher than that of the open-circuit.
