The balling is done in large balling drums using water together with an external binder as a binding media. The wet green pellets are then dried and sintered in the pelletizing machine. A narrow size distribution in green pellets is an important criterion for the pellet quality, because high permeability in the pellet bed is beneficial for both ...
balling drums. At the time, these drums were the largest iron ore balling drums in the world. Iron ore concentrates are fed with a binder into the . balling drums, where the tumbling action agglomerates them into pellets about the size of marbles.

Evolution of binder for iron ore pelletizing Binders are used in the pelletizing of iron ore aiming to improve the performance of the process in the following aspects [1, 4, 11, 16, 17]: • promoting and facilitating the balling; • increasing the green and dry strength of the pellets; • preventing the collapse of pellets in the initial ...
The balling drum equipment fundamentally consists of an inclined rotating cylindrical shell with water sprays in its inlet end, where the feed material is introduced to …
First, the dry balling drum was conditioned to relevant balling humidity by balling a small batch of the studied material for about 5 min, after which the material was discarded. Thereafter, the "real" balling began, with the production of seeds. ... From the balling of iron ore concentrates, it is known that as the raw material becomes ...
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 …
If for instance the process in which the binder is added gives too many varying outputs, then the balling drum operation will suffer. Therefore, the iron ore pelletizing process may be described as a chain of several sub-processes which …

Normally, the length of an iron ore balling drum is two to three times its diameter and the inclination 2-5 degrees. A drum of 2.5-m diameter and 7.5-m length, operating at 10.75 rpm or 40% critical speed, should produce about lo00 tons of 19-mm pellets per day. This is equivalent to a specific production rate of approximately 13 …

The balling drum segment is anticipated to reach over USD 27 billion in revenue by end of 2032 on account of its ability to control the ore balls when ...
Iron ore pelletizing plants rely on high-capacity balling drums to agglomerate ore fines and concentrates into pellets ranging from 8 – 16 mm for optimal performance in the blast furnace. Pelletizing iron ore products in a balling drum offers the following benefits: 1. Mitigation of dust …
Balling of finely comminuted solids by random coalescence and granulation of iron ore fines and other minerals by autolayering are two major size enlargement processes.. The existing kinetic model for random coalescence does not take into account the strong dependence of coordination number on the size distribution of agglomerating …
At first, iron ore fines (< 10 mm), flux fines (< 3 mm), coke breeze (< 3 mm) and other fine metallurgical wastes are blended as per pre-calculated ratio and mixed homogenously in primary mixing drums (Tupkary and Tupkary 2011). Then the raw mix is subjected to rotation in wet condition (granulation) inside balling drums converting into …
