Prediction Of Sinter Yield And Strength In Iron Ore

Jun 15, 2010 Sinter with limestone mean particle size of 1.25 to 1.52 mm yielded better sinter strength and lower RDI compared to sinter with smaller or larger limestone mean particle size. Higher sinter strength is due to better and uniform distribution of limestone particles, and better bed permeability enabled easy assimilation and effective distribution of calcium ferrite phases.

Jun 15, 2010 In sinter plant fluxes including limestone and dolomite are added to improve the sinter properties of iron ore and to provide an appropriate slag composition of the blast furnace. The raw material grain size affects the sinter process considerably because the sinter productivity and quality are strongly dependent on the green permeability of the bed, which is determined by the particle size.

(pdf) Effect Of Coke Size On Iron Ore Sintering

Sinter productivity increased with increasing limestone mean particle size due to improved sinter bed permeability. Sinter with limestone mean particle size of 1.25 to 1.52 mm yielded better sinter.

Nov 25, 2018 On the other hand, the reactivity of iron ore is significantly influenced by its grain size which determines the reaction surface area and packing density (porosity) of the sinter mix. Hence, the particle size of the iron ore is important to control sintering reactions during the sintering process.
