The energy required for firing the pellets in the indurating furnace comes from two sources. The pellet composition provides a large part of the fuel either with the addition of carbon in the pellet material or from the exothermic reaction coming from the change of phase of the ore in the firing process for instance with magnetite ore

Jun 13 2014 Use of Iron Ore Pellets in Blast Furnace Burden Pelletiing is a process that involves mixing very finely ground particles of iron ore fines of sie less than 200 mesh with additives like bentonite and then shaping them into ovalspherical lumps of 8-20 mm in diameter by a pelletier and hardening the balls by firing with a fuel
Drying has became critical to iron ore pellet production due to increasing inability to withdrawal moisture from the green pellets especially faced by goethitic iron ore producers. Most of the existing pelletiing furnaces do not support increase heating rates nor changes in furnaces length without compromise pellet

Pellet hardening takes place on the traveling grate which is part of the indurating machine. The traveling grate is covered by a refractory lined hood which is divided into the following process ones inside round brackets are an usual range of gas temperature admitted for processing hematite ore 8 A Updraft drying one UDZ
Sponge iron is a highly processed form of iron ore which contains metallic iron in the range of 83-88 obtained by direct reduction without melting it. Due to high porosity the resulting iron is called sponge iron. It is used as a raw material for manufacturing steel
The iron ore was successfully reduced to predominantly metallic iron phase when up to 30 by weight of biomass was introduced into the mixture. Reduction commenced at approximately 670C and was
Dynamic simulation of pellet induration process in. Previous models of pellet induration in straightgrate machine The original works on calculation of temperature profile in moving pellet beds date back to over four decades ago Early studies on a purely theoretical approach to modeling of the process by Hasenack et al 1975 and Voskamp and Bras 1975 presented significant insights into the
Straight grate systems do all the indurating on a single machine. Drying pre-heat indurating and cooling are all done in one integrated furnace. Metso is one of the original technology suppliers for straight grate systems having acquired the technology from Dravo and Jacobs
