In the sintering furnace, iron ore, which is the main raw material of iron, is baked together with lime and powder coke. In this process, in order to uniformly apply heat to the raw materials, various fans and blowers such as large main exhaust fan, BUF, and circulating blower are used. Fans and Blowers used for sintering equipment
Chinas Iron Ore amp; Steel Association confirmed 3000 tonnes of recycled steel raw material was imported into China from Japan in late January. It was the first domestic import of ferrous scrap ...
But no ore has moved to the docks since October 2016, according to CN, and its yard in Escanaba will remain open to serve local rail customers. Escanaba has been a transportation and trade center since 1852 and is the only iron ore port on Lake Michigan, moving raw materials to industry in Chicago and Indiana, and the midwest.
Pelletizing Fans. Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200mesh with additives like bentonite and then shaping them in to oval/spherical lumps of 8 16mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
Iron ore pellets are spheres of typically 616 mm to be used as raw material for blast furnaces. They typically contain 6472% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.
When the moisture level in raw materials is too high; often a higher capacity raw mill fan amp; large separator / classifier is required. A review of recent raw mill designs indicates that increasing...
The sintering process converts fine sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace.
Once the raw materials have been crushed into raw meal, they are transported to the kiln and Howden fans play an important role in super heating the meal into the cement clinker and then to cool the clinker. The clinker then has gypsum added and is moved into the cement mill to be ground into the final product.
Although such mills are an important component of total US steel production, the giant steel mills that create steel directly from iron ore remain essential for the initial production of steel.
