Iron ore sinter – A bulk material for blast-furnace smelting, which is made by sintering ore, limestone, fine coke, screened sinter and blast-furnace dust on special belt sintering machines. Sinter quality is determined by the Fe content of iron ore, strength, destruction during heating and reduction in a .
Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %). Normally pellets are reduced considerably faster than sinter ...

1. Iron ore - supply and demand outline 1.1 Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron .
High grade iron ore less than 10% of the total reserves. ROM iron ore with Fe less than 58 – 60% discarded as waste. After beneficiation iron ore availability can improve by about 50%. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative: 1.
Iron ore sintering. Part 1. Theory and practice of the sintering process. ... that is initially formed by the pelletising mechanism, and presented a similar structure to that of pellets.
Iron ore pelletizing systems. Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel. is supplier of both Straight Grate and Grate Kiln pellet plants.
Influence of green pellet properties on pelletizing of magnetite iron ore Sintering in the magnetite phase started earlier (950°C) compared to the hematite phase (1100°C). Therefore, the difference in sintering rates between the...
Jul 18, 2013· The ore bulk composition and the nature of the minerals in the fine ore both play a critical role in determining the type of high temperature bonding phases that form during sintering and pelletising. This paper uses the experimental determination of phase relations in model sinter and pellet systems such as Fe 2 O 3-CaO-SiO 2 (FCS) and Fe 2 O ...
P2G TECHNOLOGIES IN IRON ORE PELLETIZING PROCESS • Global iron ore production: 3220 Mt in 20141 – ~20% of the global market for pellets2 – Varies from country e.g. in Brazil ~90% of the production are ore fines, from which 70% sinter feed and the remaining 30% pellet feed3 • Who and where – Top three countries: China, Australia and Brazil

Pelletizing discs. Pelletizing discs are used in the agglomeration process to form fine iron ore into uniform green iron ore pellets. State-of-the-art operators control station allowing operator to locally start and stop the disc, adjust the speed of the disc with a potentiometer and view the .
Iron ore pelletizing, or balling, is the process of transforming fines into spherical granules anywhere from 8 – 16mm in size via tumble-growth (agitation) agglomeration using either a disc pelletizer (pan granulator) or rotary drum.
Outotec Traveling Grate Sintering is suitable for sintering a wide range of raw materials, including iron, manganese and ferronickel, while Outotec Traveling Grate Pelletizing is the industry's leading induration technology for iron ore pellet production which is designed for a wide range of plant capacities and produces uniform pellets with ...
Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of ...
Jan 01, 2015· Although iron ore concentrates are generally higher in iron grade and contain lower impurities, the finer size distribution of concentrates limits their usage in iron ore sintering. Therefore, pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces and direct reduction processes.
PELLETISING AND SINTERING. Pelletizing is the process of compressing or molding a material into the shape of a pellet. A wide range of different materials are pelletized including chemicals, iron ore, animal compound feed, and more. Iron ore pellets are spheres of typically 8–18 mm (0.31–0.71 in) to be used as raw material for blast furnaces.
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
Apr 02, 2010· Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation.
