growth of agglomerates in balling iron pellets
Iron ore concentrates are fed with a binder to the balling drums, where the tumbling action agglomerates them into pellets about the size of marbles. The use of a balling drum increases the efficiency of the steel making process by significantly reducing the amount of dust and fines that can become entrained in the blast furnace and lost as waste.

Iron ore pelletization is a two-step process consisting of pellet production in balling circuits and pellet induration in straight-grate or grate-kiln systems. Extensive applied research and plant-scale testing are directed to understanding and improving the induration process and pellet quality.
Iron Ore Pelletizing Process: An Overview | IntechOpen
Balling process: the green pellet is the rolled pellet without any thermal process. It is obtained under strict control of moisture and has a spherical shape and diameter of 8–16 mm; Induration process: the green pellets are hardened in a high temperature processing at controlled heating rates, and aiming to achieve the physical and metallurgical requirements for handling, transportation, and final application.
Introduction to Iron ore Pellets and Pelletizing processes ...
Normally pellets are reduced considerably faster than sinter as well as iron ore lumps. High porosity also helps in better metallization in DRI production. Pellets have a uniform size range generally within a range of 8 -16 mm. Pellets have spherical shape and open pores which give them good bed permeability.

Agglomeration of Particles - Mineral Processing & Metallurgy
Agglomeration is the formation of aggregate by the sticking together of feed and/or recycle materials, and it includes the formation of agglomerate nuclei. The main objective in agglomerating fines being the conversion of ores, minerals and chemicals of undesirable fineness into agglomerates characterised by a size consistency desirable for subsequent use or processing. In metallurgical ...
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].
Review of Organic Binders for Iron Ore Agglomeration
Figure 1 Green-ball growth during iron ore agglomeration. Individual iron ore particles are wetted, and pellet ‘seeds’ are nucleated. During agitation in the rotating drum or disc, small seeds can grow by consolidation of individual granules and layering of new feed material (Iveson et al 2001).
