Due to the many benefits the process can offer, pelletizing continues to expand into a growing number of markets and applications. Typical pelletizer plant applications include: Iron ore (in this case the process is typically referred to as balling) Fertilizers & soil amendments (gypsum, limestone, etc.) Industrial by-products (fly ash, EAF ...
Around 8-10 million tons of slimes are discarded during the washing process in India, containing about 48-60% of Fe every year (Prakash et al., 2000), almost 15% of the total ore mined.
There are three major iron sources: pellets, sinter, and iron ore. ... The blast furnace gas is used to heat boilers or stoves within the steel plant. 1.2. Process Description. ... The oxygen blast furnace process flow chart is shown in Fig. 19 (Zhang, H.J. et al., 2015). The current problem of oxygen blast furnace is the uneven distribution of ...
Physicochemical properties of the iron ore pellets depend on the iron oxide concentrate, gangue content and the amount of fluxes added.
processed ore include sinter and briquettes. The average iron content of pellets is 63 percent. 11.23.2 Process Description2-5,41 Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore ...

The process comprises four steps: Raw material preparation and mixing. Green pelletizing. Pellet hardening (indurating) Hearth layer and product screening. In order to adjust …
When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
1.3 Charging the blast furnace/ BOS plant Pellets are primarily used in blast furnaces and are also used in DR-plants. Occasionally pellets are used in the steel process. Pellets are stored in bunkers before charging to the blast furnace. The mixture of iron bearing materials (iron ore rubble, sinter and/or pellets) and additives (flux material)
The shaft furnace is where iron ore is converted to metallic. Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a ...
The exothermic heat of the reaction leads to a strong sinter bond in contact points between particles. As a result, it decreases the production of dust when pellets are charged into the kiln and ...
We can help our customers to determine which process is the best for their ore, fuel and pellet requirements. Our iron ore pelletizing systems combine the best features of both technologies to provide the most modern plant and to produce pellets at the lowest cost and highest quality.
