  • AMIT 135: Lesson 6 Grinding Circuit Mining Mill Operator

    Pebble mill is replaced by a ball mill or a Vertimill in the previous circuit. This is used when there is not enough pebbles available in the circuit, or all autogenous grinding produces too much fines AG Mill + Ball Mill Vertimill Pebble mill is replaced by a ball mill or a Vertimill in the previous circuit.

    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 critical problem areas were ident

  • High recirculating loads in Ball Mill Circuits Grinding

    Why do ball mills have such high circulating loads?The ball mill grinds. The cyclones separate. But the pump neither grinds nor separates. So what is the purpose of having such a big pump to maintain high circulating loads in our grinding circuit?A recent grinding bulletin addresses this question f
