Pelletizing

Pelletizing iron ore is undertaken due to the excellent physical and metallurgical properties of iron ore pellets. Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces. They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets.

Dynamic simulation of pellet induration process in straight-grate

Keywords: mathematical modeling, pellet induration, straight grate, pellet shrinkage, iron ore pelletizing . 2 I. INTRODUCTION Production of pellet as a desirable feedstock for ironmaking furnaces has exceeded 300 Mt per year in 2005, accounting for about 24% of the iron ore processed globally (UNCTAD, 2006).Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets isIron Ore Pellets and Pelletization Process IspatGuru

Iron Ore Pelletizing Process: An Overview Semantic Scholar

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. Iron ore pellets not only have excellent metallurgical and mechanical properties but are also essential raw materials for improving iron and steel smelting in the context of the increasing global depletion of high-grade iron ore resources.

By adding water to the top of the disc, iron fines are spun up along with other fines, forming pellets. The pellets are automatically graded according to particle size until 8 -16 mm pellets are discharged. Upon balling, they are dried, hardened at high temperatures of 1200-1300°C, and then cooled.Regional growth of iron ore pelletizing sinc e 1950.

Iron Ore Pelletizing Essential in Meeting Future Steel Needs

Iron ore pelletizing, or balling, is the process of transforming fines into spherical granules anywhere from 8 16mm in size via tumble-growth (agitation) agglomeration using either a disc pelletizer (pan granulator) or rotary drum. Why Pelletizing is an agglomeration process which converts very fine grained iron ore into balls of a certain diameter range (normally 8mm to 20 mm, also known as pellets. These pellets are suitable for blast furnace and direct reduction processes.Understanding Pellets and Pellet Plant Operations IspatGuru

Iron ore pellets are a man-made iron-riched ore. The pellet production method was invented in Sweden in 1912, and then began to be used in the United States in 1946 by shaft furnace. It was originally developed primarily for the efficient use of taconite mines. Taconite ore only contains about 35% iron, and this low-grade iron ore can only At present around 6–7% of iron ore slimes, out of total production, are being generated and accumulated at iron ore mine sites of National Mineral Development Corporation Limited, India. The accumulated slimes of finer size and relatively inferior grade should be utilized in an economical way for sustainable mining.
