ABSTRACT. The Chapter describes the quality parameters of pellets affecting the iron-making process and their dependence on the influencing variables. Their interrelationship with bonding in pellets and their textural characteristics are described. The influencing variables—process related, such as ore characteristics in terms of fineness and

Low-grade iron ores are finely ground and processed to recover iron-bearing minerals. However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called “pellets.” Bentonite clay has traditionally been used as a binder to make iron ore

2) Pelletizing on a disc pelletizer. The conditioned material enters the pan, and as the pan rotates, the iron ore tumbles against itself, growing in size. Once the pellets reach their desired size, they exit the pan and proceed to drying. 3) Drying in a rotary drum dryer.

Pelletizing is the process of compressing or molding a material into the shape of a pellet. A wide range of different materials are pelletized including chemicals, iron ore, animal compound feed, plastics, waste materials, and more. The process is considered an excellent option for the storage and transport of said materials.[1] The technology

ABSTRACT. The process of induration affects the productivity of pellets and their qualities: the latter influence the iron-making processes. The chemical reactions and mineralogical changes at the different stages of induration are outlined. The magnetite is oxidized to hematite, which results in bonding and bridging and, in case of hematite
