Effect of iron ore properties on its balling behaviour. The pelletization behavior of an iron ore as well as the properties of the pellets produced are affected by the various properties of the ore.

Characterization of iron ore pellets with dextrin added ... porosity and hardness) properties. Good quality pellets were prepared with organic binder, and which increases the compressive strength of dry and fired pellets. Strength results are matching with the bentonite binder pellets and it is well ... Particle size measurements of the iron ...

The composition and particle size distribution of iron ore concentrates are shown in Tables II and III, respectively.

Effect of particle size on pellet quality during pellet making has also been aimed and studied along with the development of flowsheet for beneficiation of low grade iron ore. Key words: iron ore; beneficiation; agglomeration; pelletization.

These pellets are formed by disk pelletizing of a mixture consisting of hematite iron ore, (particle size less than 50 µm) water, and lime; they are hardened in a traveling-grate furnace and the nominal diameter varies between 9 and 16 mm.

The feasibility of the innovative ironmaking technology was studied, and the effects of preheating temperature, pellet size and composition on the quality of direct reduction iron (DRI) were investigated.

An effect of a grinding method, that is ball mill and high pressure grinding rolls (HPGR), on the particle size, specific surface area and particle shape of an iron ore concentrate was studied.

the particle size, specific surface area and particle shape of an iron ore concentrate was studied. The particle size distribution was meticulously examined by sieve, laser and image analyses.

The raw material grain size affects the sinter process considerably because the sinter productivity and quality are strongly dependent on the green permeability of the bed, which is determined by the particle size distribution of the raw materials, the granulation effectiveness and by the sintering process itself.

The particle size of iron ore in the ore slurry is less than 45 micro meter for around 80 % of the particles. Additive materials (such as dolomite, limestone, lime or olivine etc. depending on the quality of the pellet to be produced) is added to the slurry.

Data on the influence of alumina and silica are therefore primarily of interest for assessing the likely effects of uncontrollable changes in the gangue content of iron ore used as pellet plant feed. Lime and Blaine index are variables which can be controlled at the feed preparation stage of a pellet plant.

The quality of iron ore pellets is evaluated mainly on the basis of the following indices: chemical composi- tion, particle-size distribution, compressive strength, impact and abrasion strength in a drum, and destructibility dur-

In the case of iron ore mining, due to the recent shortage of high grade ores, the particle size of the final product is becoming finer and finer. Thus, the iron ore concentrate needs pelletizing to allow its use in the reduction processes, both in blast furnaces or direct reduction reactors.
