iron ore sinter feed size distribution

Prediction of the granule size distribution of iron

Kinetics of iron ore sinter feed granulation -

01-08-1990  The kinetics of iron ore sinter feed granalation were shown to have a major impact on granule size distribution. At laboratory scale, it was shown that granule growth continued until a maximum stable size distribution was achieved. Two stages to granule growth were observed. Fine particles quickly adhered to intermediate and large nuclei particles.

DEM study on size segregation and voidage

01-11-2019  The size segregation and voidage distribution down a green bed formed on an iron ore sinter strand were investigated experimentally and using Discrete Element Method (DEM). The simulated and experimental results showed that an increase in feed rate (from 6 kg/s/m to 18 kg/s/m) significantly decreased the level of vertical size segregation and the granule packing voidage of each bed sub-layer.

Iron Ore Analysis Process Optimization

Decreasing ore grades of existing or new iron ore deposits require predictive solutions to efficiently sort and blend iron ore for optimal and profitable beneficiation and downstream processing. Elemental and mineralogical composition as well as predictive models for the upgradability, based on metallurgical parameters, such as washable constituents, play an important role for iron ore producers.
