Pelletization is the process of transforming iron ore fines into spherical pellets through agglomeration and induration. These pellets are then used as feed to a blast furnace or direct reduction systems to produce iron. As the only supplier in the world, Metso offers both straight grate and gratekiln technologies for any required pelletizing ...

Production of pellet as a desirable feedstock for ironmaking furnaces has exceeded 300 Mt per year in 2005, accounting for about 24% of the iron ore processed globally (UNCTAD, 2006). The production of iron ore pellets involves two major steps, forming the "green" pellets in rotary disks or drums, followed by their heat

Iron Ore Pellet an overview | ScienceDirect Topics

In a DR process, iron ore pellets and/or lump iron ores are reduced by a reducing gas to produce DRI or hot briquetted iron (HBI). Depending on the generation of the reducing gas, two different DR processes are commercially available: gasbased and coal/oilbased. In the gasbased DR process, the reducing gas is produced by chemically reforming ...

Iron ore is one of the two essential inputs for producing direct reduced iron (DRI); the other being natural gas or another hydrocarbon fuel that can be reformed to create a reducing gas rich in CO and H2. Although direct reduction processes can operate with pellets having an iron content of 65% or lower, typical of blast furnace (BF)grade ...

Pelletizing Wikipedia

The process of pelletizing combines mixing of the raw material, forming the pellet and a thermal treatment baking the soft raw pellet to hard spheres. The raw material is rolled into a ball, then fired in a kiln or in travelling grate to sinter the particles into a hard sphere. [4]
