10/07/2017 The iron ore pelletizing process consists of three main steps: Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives—anthracite, dolomite—and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process; Balling process: the green pellet is the rolled pellet

Iron Ore Pelletizing Process: An Overview

Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s. Bentonite promotes the forma- tion of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing.

(PDF) Cooling process of iron ore pellets in an annular

In this period, air flow, heat transfer, and iron ore pellet oxidation take place at the same time [6][7][8]. Finally, the pellets are cooled, the cooling air is heated, and the waste heat is recovered [9][10]. The techno-logical flow chart is shown in Fig. 1. The outlet and the inlet of an annular cooler are neighbors and are separated by a partition. The inlet is at the roof and the outlet

The Iron Pelletizing Process: Part One :: Total Materia

The pelletizing process is a process which contains numerous sub-processes, or process segments. On the way from the mine to a final product, the iron ore goes through the following main process segments: 1) The iron ore is crushed and the waste rock is removed. About 85 % of the particles should be less than 44 μm (in length, width, or height).

Ore Pellet an overview ScienceDirect Topics

There are three major iron sources: pellets, sinter, and iron ore. Metallurgical coke is used as the fuel and reducing agent in the blast furnace process. Coke is the product of carbonization (or distillation) of mainly bituminous coal. Flux is also added to the blast furnace charge to absorb impurities present in the iron sources and coke ash.

Iron Ore Pellet an overview ScienceDirect Topics

In a DR process, iron ore pellets and/or lump iron ores are reduced by a reducing gas to produce DRI or hot briquetted iron (HBI). Depending on the generation of the reducing gas, two different DR processes are commercially available: gas-based and coal/oil-based.

Iron Ore Pelletizing Process: An Overview

Bentonite is an effective, widely used binder in the iron ore pelletizing process. Its low price is an important factor for its extensive use. However, bentonite incorporates silica and alumina, which are undesirable contaminants to pellets. Additionally, it is a natural material with variable composition depending on its origin. Obtaining a suitable binding effect requires a relatively large

The iron pelletizing process is often associated with low grade iron ore following a range of liberation techniques to prepare and make suitable for the blast furnace. In summary, pelletizing is achieved by combining the iron ore with water and a specific binder which is then rolled up in drum to produce relatively uniform pellets which can then be easily handled in downstream processes.
