Nov 1, 2014 . FL and Kobe Steel, Ltd., Japan have entered into a license agreement enabling FL to market, design and construct iron ore pellet plants using Kobe Steel's pelletizing process called the KOBELCO® pelletizing system.
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.

grate-kiln based pelletizing plants operate in production regimes that well exceed their intended design. Coupled with the rising energy and environmental costs, this has necessitated a more systematic mathematical study of. Modeling and Simulation of Iron Ore Pellet Drying and Induration Process. Jianhui Wang1, Jun.
Abstract. A mathematical model of drying and preheating processes in a traveling grate was presented based on the laws of mass, momentum, heat transfer, and drying semiempirical relations. A field test was systematically carried out in a traveling grate. The effects of pellet diameter, moisture, grate velocity, and inlet gas.
In the steel production process, there are two main steps: the extraction of iron ore and its transformation into steel. But what about pelletizing? Is it a mining or a metallurgical activity?
__ Because of the decline in steel demand, the iron ore pellet industry is undergoing a process of rationalization and consolidation. Total apparent U.S. consumption of pellets increased significantly in the period of this ~nvestigation, rising from 40.~ million long toni in 1983 to. 53.9 million long tons in 1984, and then falling.
iron ore industry. Originally the pelletizing process was developed in the USA to treat the ultra-fine mineral dressing products obtained from the upgrading of Mesabi ore and has been utilized to provide a blast furnace feed product with Fe grade of about 65% (Ball et al., 1973). In pelletizing, iron ore, water and a binder are.
Our heavy-duty 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.

Iron Ore Pelletizing. Iron is the world's most commonly used metal. So important is iron, that it has been suggested that it is more integral to the global economy than any other economy, except perhaps oil. Iron ore is the raw material used to make pig iron which is one of the main raw materials used to make steel.
During the 1950's, Cliffs pioneered a process that beneficiated the lower-grade ore into high quality, custom made pellets. Since that time, Cliffs has remained on the cutting edge of this technology. While iron ore pellets are made in other parts of the world, it can be said that competitive pellet producers are still “catching up”.
