Iron Ore Calcination Kiln for Iron Oxide Production Line Price in China

Iron ore calcination kiln for iron oxide production line price in China

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides

and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of

magnetite (Fe3O4, 72.4% Fe), hematite (Fe2O3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH).n(H2O)) or siderite

(FeCO3, 48.2% Fe).

Iron ore calcination kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. 

Materials produced using rotary kilns include:cement, lime, refractories,metakaolin,titanium dioxide,alumina,vermiculite,

iron ore pellets, zinc oxide,etc.

The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be 

processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, 

and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as 

the process material (co-current), but usually in the opposite direction (counter-current). 

The fuel for this may be gas, oil, pulverized petroleum coke or pulverized coal.

Iron ore calcination kiln technical parameter:

In Iron ore calcination kiln, under the high temperature of 800~900°C, and with help of reducing agent of coal, Fe2O3 is reduced into Fe3O4. 

In this process, attached water and crystal water in the 

ore is firstly removed. The main Physicochemical process are as follows:

Fe2O3·nH2O(H2O)+ heat → Fe2O3·nH2O + H2O↑ 

(removing attached water)

Fe2O3·nH2O + heat → Fe2O3 + nH2O↑ 

(removing crystal water)

C + 6Fe2O3 → 4Fe3O4 + CO2↑ + heat

(reduction magnetization)
