Improved Pellet Fine Removal. In the mining and aggregate industry, the removal of impurities such as taconite fines from whole pellet products is an important task. The pellet fine removal system is a low cost means of separating contaminants such as chips and dust that slow down the flow of heat in blast furnaces from iron bearing pellets.
The pellet industry is again gaining momentum due to changed economic scenario as the iron ore cost has increased considerably. The iron ore pellet making capacity of India ( 36.6 mt) is shown in Fig. 13. Fig. 13 : Iron ore pellet making capacity The energy consumption by such pellet plants in India is more than global practice (Fig. 14).
The pelleting process starts with a bin (Figure 1, Item 1) in which the mixture of mash is stored. From there, the mash will flow by gravity into the pellet mill (Figure 1, Item 2). This machine is usually located on the ground or main work floor level. The hot, extruded mash (pellets) flows by gravity into a …

The pelletizing discs used for agglomerating iron ore concentrates into pellets are remarkable for their very narrow particle size distribution with a target size of 10 – 14 mm, important for DR-processes. The powder-type feed material is formed into pellets with …
[Source: C-Tempo, Ministry of Mines / LKAB, Sweden / Association for Iron & Steel Technology] Benefits of Pellets In Iron & Steel Making 31 • Good quality pellets can be produced at low SiO 2 levels (1.5 to 3.5%) whereas it is difficult to produce quality sinter at a SiO 2 level of less than 4.5%, which helps slag volume reduction by 40to 45%.
HYFOR (Hydrogen-based Fine-Ore Reduction) is a novel direct reduction process for iron ore fines concentrates from ore beneficiation, developed by MHI Group company Primetals Technologies. It builds on fluidized-bed reduction technology, does not require any agglomeration (such as sintering or pelletizing), and uses on hydrogen as a feedstock.
Pellet production capacities range from 800 000 t/a up to three million t/a and the quality of the pellets can be flexibly adjusted according to production requirements. The ever-higher portion of fine and ultrafine iron ore from mining sites means that the pelletizing process is becoming more important for ore agglomeration.
High grade iron ore less than 10% of the total reserves. ROM iron ore with Fe less than 58 – 60% discarded as waste. After beneficiation iron ore availability can improve by about 50%. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative: 1.
