The drum rotating speed does not significantly affect the adhesion of small particles. However, the existence of baffles can significantly increase the number of iron This investigation mainly focused on revealing the importance and function mechanism of intensive mixer on sintering performance with 100% fine-grained iron ore Importance of intensive mixing on sintering with fine-grained iron ore

Iron Concentrates Proportion The particle size of the raw materials is directly related to the granulation of the sintering mixture. The number of nuclear particles will be Comprehensive Technologies for Iron Ore Sintering with
To study the mixing effect of powder particles in a high speed shear mixer (HSSM) and cylinder mixer (CM), numerical simulation based on discrete element method was Comparisons of iron ore granulation and sintering performance between horizontal high-shear granulators and drum granulators Semantic Scholar. DOI: Comparisons of iron ore granulation and sintering
Also, the best drum speed was observed to be 15 revolutions per min (rpm) although the higher drum speeds (e.g. 40 rpm) showed higher bed permeability values (about 54 JPU) High-quality iron ore resources are getting scarce and low-grad iron ores are increasingly utilized in iron and steel production [1]. [10] studied the effects of drum parameters on iron ore granulation and found that the optimal granulation performance was achieved when the drum rotation speed and filling rate were at 18 rpm and 12%Comparisons of iron ore granulation and sintering

Generally, four granulation mechanisms have been identified [1], including auto-layering, coalescence, adhesion of micro pellets, and two-stage layering.For iron ore sintering, due to the existence of core particles (large ore with a size of 5–10 mm) and a large proportion of fine particles (with a size of <1 mm), the main mechanism is so-called Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine Iron Ore Agglomeration Technologies IntechOpen
Mixed iron ore, dolomite, limestone, coke breeze and return fines are the main raw materials for iron ore granulation and sintering process. Table 1 lists the chemical compositions of the raw materials used in this work. Mixed iron ore and return fines have high iron content and low impurities of CaO, SiO 2, Al 2 O 3 and MgO. Dolomite and The proposed method by mixing SO-B with a high amount of goethite-type iron ore fines was found to be an effective way in improving the granulation and assimilative characteristics of ore blendsGranulation Behavior of an Iron Ore Sintering Mixture Containing High
16.1. Introduction. Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world’s high-grade competent iron ore resources.The experiment was performed using a new designed granulating equipment. It is to explore the influence of the process parameters of the equipment on the granulation effect during the granulation process. The granulation mixer is shown in Fig. 1.

Granulation is an important process in iron ore sintering to increase particle size for better permeability. In this study, the granulation of mixed iron ore, coke, and flux in a rotating drum is studied by the discrete element method.The results of mixing indicate that the particle-particle collision number is closely related to the composition of raw The iron ore E sample and five Al-additives were compressed into tablets with 10 mm in diameter and 8 mm in height at a set pressure of 200 N, respectively. After dried, the iron ore tablet was put upon the Al-additive tablet and roasted at 1310 °C in the air atmosphere for 5 min in the horizontal tube furnace.Improving High-Alumina Iron Ores Processing via the
