Grate Sintering Iron Pellets - lecoudmain.be

Ironprocess grate sintering iron pellets · A minipot test is designed to indurate green balls produced in batch balling studies and produces about g of fired pellets for physical quality analyses (%+1/4 after tumble indices and fired

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.

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.

Drying and preheating processes of iron ore pellets in a ...

Oct 09, 2010 · A mathematical model of drying and preheating processes in a traveling grate was presented based on the laws of mass, momentum, heat transfer, and drying semiempirical relations. A field test was... Drying and preheating processes of iron ore pellets in a traveling grate | SpringerLink

Pelletizing - Wikipedia

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. The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets, decreasing the resistance to the air that flows up through the layers of material during the smelting.

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.

What is the difference between pellets and sinter? - Quora

Sep 13, 2016 · 1.Pellets are spherical agglomerates whereas sinters are irregular shaped agglomerates. 2. In pellets porosity is more at surface whereas in sinter porosity is spread almost homogeneously . 3. Pellet is made in the presence of moisture and binder ...

Traveling grates - liming

After feeding the pellets to the traveling grate, the unit operations of green ball drying, concentrate dehydration, partial calcination, and partial induration are performed on a traveling grate, whereupon heat transfer occurs in zones of the grate from the cross flow of process gas (hot air) repeatedly passed through the pellet bed in a modified countercurrent fashion.

Iron Ore Pellet Kiln Burners - FCT Combustion

A range of high-quality, 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 applications such as hot gas generators, calciners and pre-heat chambers.
