Green iron ore pellets are nearly spherical agglomerates produced in balling discs or drums from a mixture of fine iron ore concentrate, agglomerating agents and water [1]. These pellets are then indurated, typically in horizontal travelling grate furnaces, reaching their hardened state which allows handling without significant …
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 ...
A typical iron ore balling circuit may ha ve drum diameter ranging between 3 − 5 m and 8 − 10 m long and circulate about 400 − 1200 ton/h producing 100 − 300 ton/h on-size p ellets.

The most commonly employed agglomeration technique is pelletizing by which a mixture of iron ore, water, and binder is rolled up in a mechanical disc or drum to produce …
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. The use of a balling drum increases the efficiency of the steel-making process by

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 …
Agglomeration of iron ore is commonly done in large balling drums or discs using water together with an external binder as a binding media. The mechanical strength of wet green pellets controls the productivity of the balling circuits and influences the productivity of the subsequent firing process, as well. A critical parameter in balling is to find a suitable …

of iron-ore concentrates in balling drums. The charge entering the drum is partially layered onto pellets in the already-circulating load, and microgranule-nuclei are formed. This event is confirmed by the sharp increase in the number of pellets and the decrease in their mean weight and diameter (Fig. i). As the ratio of the weight of ...
Pelletizing is an agglomeration process which converts very fine grained iron ore into balls of a certain diameter range (normally 8mm to 20 mm, also known as pellets. These pellets are suitable for blast …
