  • 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...

  • Understanding Basic Electronics is Easy

    An electrical current is the flow of electrons in a wire. Electrons flow when you have a “closed loop” – a path from the negative to the positive terminal of a battery. For example if you connect a small light bulb to the positive and the negative side of a battery, you will get a closed loop where electrons can flow and make the lamp shine.
