Quality requirements of iron ore for iron production
Therefore, the TI of iron-bearing materials should be > 95% + 6.3 mm and the RDI < 12% − 6.3 mm, as well as CCS > 225 kg. More fines in the shaft furnace decrease the bed permeability, leading to nonuniform gas flow and temperatures in the shaft as well as difficulties in injecting the reducing gas through the bustle.Introduction. This International Standard concerns one of a number of physical test methods that have been developed to measure various physical parameters and characteristics and to evaluate the behaviour of iron ores, including reducibility, disintegration, crushing strength, apparent density, etc.ISO 4700:2015(en), Iron ore pellets for blast furnace and direct

Instruments for Physical Testing of Iron Ore Pellet Crushing Strength
of Iron Ore Pellet Crushing Strength Determinator RB 1000 The RB 1000 Iron Ore Pellet Crushing Strength Determinator is an automated system for the determination of the crushing strength of fired iron ore pellets and reduced iron ore pellets, according to ISO 4700 Standard and ASTM E 382-83 Standard.Iron ore fines were classified into three size ranges (SR1(−0.25 + 0.1), SR2(−0.1 + 0.05) and SR3(−0.05)mm). Pellets of the above material were prepared using lime as a binder for basicity 0, 1 and 2 respectively, to observe hardening and reduction behaviour. Hardened pellets were characterised using cold crushing strength and porosity.Direct reduction of fluxed iron ore pellets made from coarse iron ore
