A brief introduction to recent developments in iron ore pelletizing is provided in this chapter, including the world output of fired pellets, pellet production processes, preparation of pellet...This study corroborates that the iron ore mineralogy has significant effects on green pellet growth and its properties by both experimental and mathematical arguments. In this context, three iron ore samples with different loss on ignition (LOI): 2.64, 4.85 and 9.19 wt.% were taken. The mineralogical differences were investigated through Investigation on Loss on Ignition to Study the Effect of Iron Ore

[PDF] KOBELCO Pelletizing Process Semantic Scholar
Kobe Steel's history of pelletizing plants began when the company built a plant at its Kobe Works in 1966. This paper introduces the history of pelletizing plants, including process outlines and the latest achievements in the construction of plants overseas. In the past, plant owners had focused mainly on the quality of the product pellets and plant equipment, as Pelletizing process plays a very important role in ironmaking industry [1, 2], in which iron ore powders are agglomerated with water in a rotating disk pelletizer to produce so-called green pellets.The quality of green pellets greatly affects the energy consumption of the follow-up induration process (drying, preheating, and firing) A simple image-based method for online moisture content

Vision-based size classification of iron ore pellets using
In an iron ore pelletization plant, pellets are produced inside a rotating disc pelletizer. Online pellet size distribution is an important performance indicator of the pelletization process. Image processing-based system is an effective solution for online size analysis of iron ore pellets. This paper proposes a machine learning algorithm for The green pellet size range for the three iron ore samples was optimized on the basis of disc inclination, disc rpm and retention time of pellet on the disc pelletizer. As per the commercial applications, the average size of the fired pellets is suggested to be in the range of 10–12 mm (> 80%), however during heat-hardening process of greenMineralogical investigation on preheating studies of high LOI iron ore
