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. Metso is the only supplier in the world that has both the Straight Grate and the Grate Kiln process for pelletizing.Get Price
The plant took iron ore concentrate and produced superior iron ore pellets which are spheres of high iron content and uniform quality for blast furnace and direct reduced iron feed. Since then, GrateKiln systems have been used for over 50 plants, on both magnetite and hematite ores, with an installed capacity of over 115 million tpy.
Iron Ore Pellet Kiln burners can also be used in a number of other applications such as hot gas generators, calciners and preheat chambers. Designed for maximum flexibility, the range offers exceptionally robust allround performers that can efficiently use various gaseous or liquid fuels.

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process
Pelletizing of iron ore is a method of Swedish origin, patented in 1912 by AG Andersson Yamaguchi et al., 2010. The process was developed in the USA in the 1940s, and the first commercial plant started operation in Babbitt, Minnesota in 1952. The first iron ore pellet plant of the gratekiln type was established at Humboldt Mine, Michigan in
