Pelletization Plant - Williamson Corporation

In the pelletization process, very small iron ore particles, called fines, are fused into uniform sized pieces that may be fed into the blast furnace. The ore fines are mixed with a binder, called bentonite, and then fused together in a rotary kiln to form small, round pellets of iron ore. Pelletization plants are usually located at or.

Effect of recycling blast furnace flue dust as pellets on the sintering .

Introducing these dust fines in the sintering process proves to be very harmful for different operating parameters. Thus, this study aims at investigating the production of pellets resulting from these fines, using molasses as organic binder and its application in sintering of iron ore. The sintering experiments were performed.

Several attempts have been made to develop a process for cold bonding iron ore pellets using either calcium silicate, line-silica, calcium carbonate, .. sizes, and from more than one source, such as a combination of iron ore material fines with steel mill wastes, mill scale, BOF dust, EAF dust and ore sinter fines.

Development of carbon composite iron ore micropellets by using the .

Iron ore microfines and concentrate have very limited uses in sintering processes. They are used in pelletization; however, this process is cost intensive. Furthermore, the microfines of non-coking coal and other carbon-bearing materials, e.g., blast-furnace flue dust (BFD) and coke fines, are not used extensively in the.
