The iron particulate materials, typically having a size range of from about mm to 6 mm, include ore fines, sinter fines, BOF and EAF dusts, mill scale, and the like. Powdered carbonaceous material, such as ground coal or coke, may also be added to the pellets.
The feasibility of producing Direct Reduced Iron from coldbonded selfreducing composite pellets made from Anglo American Kumba Iron Ore Sishen upgraded slimes was considered on laboratory scale. Composite pellets were made by mixing Sishen upgraded slimes, coke and different binders using a pelletizing disc by addition of moisture.
It utilizes iron ore microfines and coal fines or coke fines or carbon containing waste fines in iron making or sintering. The micropellets provide energy to the sinter bed for reduction in coke breeze consumption. 3848 % reduction in coke breeze has been found when 38 % blast furnace flue dust containing pellets were mixed with iron ore in ...

Aug 03, 2016· Cold bonding is a lowtemperature alternative to heat induration. Pellets can be cold bonded using lime, cement, sponge iron powder, and organic materials such as starch and flour. Cold bonding consumes less energy than heat induration, and has found favor for bonding selfreducing pellets and for refractory ores that are difficult to heattreat.
Cold Compression Strength (CCS) Test RB 1000 RB Automazione. According to ISO 4700, ASTM E 382 and IS 8625 Standards, RB 1000 is a fully automatic system for determination of the crushing strength of fired iron ore pellets and reduced iron ore pellets.
