Iron Ore: Lump iron ore in the size range of 520mm can be used in all coal based rotary kiln processes. In gas based processes 70% iron ore pellets and 30% lump iron ore of 1030mm are being used. In general high grade iron ore of 65% minimum Fe (total) with less decrepitating characteristics is preferred for use in rotary kiln.

processing the iron ore after extraction onsite in the Kiruna area to iron ore pellets. The thermal part of the process, where iron ore is sintered to pellets, requires very high temperatures and has to be carried out in special kilns. One of the equipment options is a combination of a straight grate and a rotary kiln, where the pellets are

The rotary dryer is widely used for drying the chalk slags, coal powder, slags, clay and other materials in the building materials, metallurgy, chemical industry, cement industry. The rotary dryer has a better adaptability and can dry various materials with a simple and reliable operation.

The serious deposits on the refractory bricks are found in the grate kiln in iron ore pellet plants, which significantly influence the pellet production. The effect of the combustion reaction of pulverized coal on the deposit formation in kiln during iron ore pellet production was investigated in this work.

Iron Ore/Taconite In the ironmaking process, the blast furnace or directreduced iron (DRI) plant will typically use iron ore pellets, which are created when iron ore fines are agglomerated and heated using a rotary kiln.

Apr 23, 2014· The Pelletizing System is a gratekiln process where iron ore pellets undergo heat treatment in two stages. Iron ore and binding agents are ground and formed into "green balls," the unfired pellets. The green balls are sent to a traveling grate where they are dried and preheated in the preheating furnace.
