Pelletizing - an overview ScienceDirect Topics

01/01/2012  Pelletizing differs from other agglomeration techniques in that the powdered ore is first formed into a “green” pellet or ball, which is then dried and hardened in a separate step, usually by heating. Green pellets are made by combining moist ore with a binder and rolling it into balls using either a pelletizing disk or a pelletizing drum. The green pellets are then dried, preheated, and finally

Upon balling, green pellets must be fired in order to cure into their final, hardened form. This is carried out through induration – a thermal treatment that heats the pellets to just before their melting point, causing them to become extremely hard. This is typically preceded by a drying step, which may be carried out in the induration unit, or in a separate device. After induration ...

Iron Ore Pelletizing Process: An Overview

internally heating the ball [7]. Pellets are obtained byadding an appropriate amount of water to the iron ore concentrate; this is a fundamental factor in the formation and growth of pellets, which creates a surface tension that holds the mineral grains cohesive, thus allowing their handling [6, 8]. This cohesive tension of fine particles due to water is called neutral tension. Neutral tension ...
