Pelletization an overview ScienceDirect Topics

The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization: .In comparison to sinter and iron ore, pellets exhibit uniform shape and size. However, pellets also exhibit higher swelling index that poses serious problems during the blast furnace operation. L.-S. Yuan, Decreasing bentonite dosage during iron ore pelletising. Ironmak.

Iron Ore Geoscience Australia

Iron (Fe) is a metallic element that constitutes 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.When dry grinding is selected the moisture required for pelletizing must be provided either by wetting the ore and mixing prior to balling or by adding all the moisture in the balling device. To date only the balling disc has operated with a dry feed. Based on power consumed per ton of final product, generally the power consumption in theFine Dry Grinding of Iron Ore for Pelletizing 911 Metallurgist
