Iron Ore Pellet Process

Pelletizing Process

Pellets are made from iron ore that is finer than that used for sintered ore. The ore fine is formed into spheroids, called green balls, approximately 12mm in diameter. The green balls are fired into product pellets. The pellets are used as the raw materials not only for blast furnaces but also for gasbased direct reduction furnaces, the process becoming popular among natural gas producing ...

Iron Processing

Our heavyduty iron ore balling drums are relied on by some of the industry's top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product. Additionally, this approach offers significantly ...
