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). The production of iron ore
Keywords Pelletizing .Agglomeration .HPGR .Milling 1 Introduction Modern iron ore pelletizing process operations may be divid-ed into two main process sections: feedstock preparation and agglomeration processes. In most plants, the required particle size distribution (PSD) is obtained through the wet ball mill circuit.
A summary of the physical and chemical characteristics of the feed to the pelletizing disc is presented in Table 1. Green pellets were produced in a one-meter diameter disc pelletizer (Eirich , model TR10) angled 68° from horizontal plane. Rotational speed of the disc was maintained constant at 16 rpm (37% of critical).
There are two main types of pelletizer that are used to produce iron ore pellets at industrial scale, the rotary drum and the disc. Besides iron ore agglomeration, these pelletizers can also be used for other materials such as copper ore, gold ore, coal, and fertilizer [12].
The constant demand for iron ore leads to the need to mine even low-grade deposits. The diminished quality of natural resources is countered by economic, ecological, and technological restrictions that require the processing of the extracted iron ore. An enrichment of iron ore can be achieved by separating unwanted components. This …
Learn how iron ore is pelletized or balled to produce high-quality pellets for the steel industry. Find out about the process, equipment, and testing involved in iron ore …
The process of pelletizing iron ore on disc pelletizers is mathematically modeled. Different methods of regression analysis are used to describe the pelletizing operation, and the equations that are obtained are compared with one another. The objective function is optimized based on the yield of green pellets of the class (–14+5) mm.
The iron ore pellet holds a pivotal role in the ironmaking process, enabling the utilization of high-grade ore and the upgrading of …
