2018.7.11 The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking.

2008.4.9 Magnetite iron ore pellets are produced by agglomerating moist, finely ground magnetite concentrate together with a binder in balling drums or balling discs to pellets, typically between 9 and 15 mm in diameter. In the Grate Kiln pelletizing process, the wet green pellets are loaded on a travelling grate with a bed height of 23 cm.

2022.12.1 At temperatures above 1100 °C, due to the sintering of hematite particles and formation of slag phases, which are either present as gangue in concentrate or added as a binder before the pelletizing process, the CCS is significantly increased. At these temperatures, the CCS of HPGR pellets is much higher than BM pellets.

2022.3.4 It is well known that pelletizing is a more eco-friendly iron ore processing technology than the sintering process, and its carbon emissions account for only 20~45% of those of the sintering process. 14,15,16 As confirmed in a previous study, 12 limonitic nickel laterite possesses good ballability and grindability due to its good hydrophilicity ...
Read More2023.3.28 In this paper, low-grade limonitic nickel laterite and chromite were synergistically utilized via the hybrid sintering process (i.e., pellet-sintering process) for high-quality Ni–Cr sinter preparation and great carbon emission reduction. Under the optimum process conditions, Ni–Cr sinter indices were substantially improved in the pellet
Read More2012.3.29 Grate process is an important step in grate-kiln pellet production. However, as a relatively closed system, the process on grate is inaccessible to direct detection, therefore, it is hard to control. As a result, mathematical models of temperature distribution, moisture distribution and oxidation degree distribution in pellet bed, with good

2022.10.20 At about the same time, some researchers were looking for an alternative process to sintering, especially in areas in which very fine ores or concentrates were available. This was the beginning of the pelletizing process. 5.1 Sintering. Iron ore sintering plants are associated with the manufacture of iron and steel, often in integrated steel mills.

Abstract. A study of pelletization of one imported chromite concentrate with coarse site, poor ballability and refractory roasting performance was conducted in small scale tests, and high pressure grinding rollers (HPGR) was used to improve the pelletization. The mechanism of HPGR was revealed by means of SEM images and optical microscopy.
