    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

    Basic Ball Mill Grinding Circuit

    Ball Mill Product Classifying. One passage of ore through a mill is seldom enough grinding to release gold and silver or other minerals from the gangue that encloses them; therefore, a classifier is worth installing to separate the sand from the slime and return the former for further grinding or for their separate treatment.
