In indirect calibration or reverse calibration, a bulk property is measured, such as the distribution of particle size, bulk (packing) density and angle of repose [93], and then a set of simulation parameters is changed until the measured bulk properties are matched. A calibration method is used to simulate and optimize the handling process of ...

Iron Ore Pellets. Iron ore pellet is a type of agglomerated iron ore fines which has better tumbler index when compared with that of the parent iron ore. Iron ore pellets are widely used as a substitute of lump ore for the production of direct reduced iron (DRI) and in the blast furnace (BF) for the production of hot metal.
