Samples were also collected from beneath the grates in active induration furnaces at four taconite processing facilities. An important distinction between taconite operations is that some use "grate-kiln" furnaces (Fig. 1) while others operate "straight-grates" (Fig. 2). Grate-Kiln facilities dry and heat pellets on a grate, but final ...
Iron Ore/Taconite. In the ironmaking process, the blast furnace or direct-reduced iron (DRI) plant will typically use iron ore pellets, which are created when iron ore fines are agglomerated and heated using a rotary kiln. Many producers use a traveling grate and rotary kiln to heat the pellets to temperatures as high as 800°C to 900°C in the ...
