-Pelletizing Process can produce superior and various quality pellets because of application of rotary kiln where pellets are heated and fired unifomly, know-how of plant operation & quality control, and advanced process control system. And the process can use various iron ores such as magnetite ore, hematite ore, dry or wet material.
15.1. 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.
Abstract A 3-D mathematical model was presented for the cooling process of iron ore pellets based on the laws of mass, momentum, and heat transfer. The flow, pressure, and temperature fields were obtained by numerical simulation with the commercial software FLUENT.

The pellets discharged from rotary kiln is about 1250 o C and is uniformly distributed on the pellet cart of annular cooler through receiving hopper of annular cooler. The pellet is then cooled to below 100 o C and is further oxidised in the annular cooler so that the FeO content is reduced to below 1%.
Iron Ore and Pellets Iron ore has historical importance in the mining industry since it was a key catalyst in precipitating the Industrial Revolution in the mid-17th century. Iron ore is the mines core product of Pellets portfolio.Our iron ore is of superior quality and passes through a mineral research process based on cutting-edge technologies.
Preparing Iron Ore for Pelletizing (Balling) Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the ...

Plant overview Grate-KilnTM iron ore pelletizing system The first Grate-KilnTM system pellet plant was installed in 1960. The plant took iron ore concentrate and produced superior iron ore pellets (which are spheres of high iron content and uniform quality) for blast furnace and direct reduced iron feed.
Considering the current problems of low temperature of recovered gas, the direct gas emission of the fourth cooling zone in the operation of the annular cooler, thermal airflow process for the annular cooler is improved by analyzing the thermal airflow process and the structure of the annular cooler and using the principle of repeated convective heat transfer.
