· Feb 23, 2013· Iron ore pellets and Pelletizing processes. Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
· The pelletizing process is a process which contains numerous sub-processes, or process segments. On the way from the mine to a final product, the iron ore goes through the following main process segments: …

· The green pellets are first dried and then preheated (partially hardened) on a 1-ft by 10-ft-long traveling grate containing one updraft drying zone and two downdraft preheat zones. Pellets are then indurated in a 34-in-diam by 35- ft-long rotary kiln pitched at a slope of ¼ in/ft and rotating at a speed of 1 rpm.
· That waste undergoes a pyrolysis process resulting in a biomass charcoal, which was tested in the same pilot plant pot grate of iron ore pelletizing of this study. That waste was dosed with satisfactory results, with good replacement of anthracite fines, ranging dosage from 10% to 25%.
· The major areas or process are the concentrator, balling, induration and handling. The concentrator is where the ore is ground to a fine size typically 80% - 45 micron powder and separated from other impurities by magnetic separation and flotation. The balling area is where the powdered ore is mixed with water, binder
· Abstract This paper summarizes more than a decade of systematic studies of the flow field in an iron ore pelletizing rotary kiln using computational fluid dynamics (CFD) on simplified models of a real kiln. Physical, laser-based experiments have been performed to validate part of the numerical results.
· Pelletizing as app.lied to iron ore agglomeration involves the preparation of spheroidal masses from a fine moist concentrate, followed by high-temperature firing to produce a final product. The preparation of moist sphercrids is generally designated as balling. This produces the so-called green pellets or balls.
