Sintering Iron Ore Pellets Mining Machinery. compact burners, specifically designed for iron ore sintering and pelleting plants using traveling grate kilns. Iron Ore Pellet Kiln burners can also be used in a number of other appliions such as hot gas generators, calciners and preheat chambers.

Iron ore pellets and Pelletizing processes – IspatGuru

Normally pellets are reduced considerably faster than sinter as well as iron ore lumps. High porosity also helps in better metallization in DRI production. Pellets have a uniform size range generally within a range of 8 -16 mm. Pellets have spherical shape and open pores which give them good bed permeability.

The Sintering Process of Iron Ore Fines – IspatGuru

Mar 09, 2013 · This agglomeration is in the form of micro-pellets. These micro pallets assist in obtaining optimum permeability during the sintering process. These micro pellets are then conveyed to the sintering machine and charged. A layer of controlled size sinter (bedding) is fed to the bottom of the sinter machine grates for the protection of the grates.

Iron ore pelletizing systems - liming

Both straight grates and grate kilns dry the pellets out in a drying section, then bring the pellets up to a temperature of about 800-900 °C in a preheat zone, then finish the induration process at roughly 1200-1350 °C. The pellets are then cooled to a suitable temperature for transporting to a load out facility.
