Formerly agglomeration was used in a purely physical way, as a process of size enlargement. Fine ore isn't desired in the blast furnaces, therefor several agglomeration processes were designed, but two of them are used in the iron industries. It called Pelletizing and Sintering. It is generally known fact that a higher charge of sinter and ...
The present patent document refers to the products and processes of Ceramic Proppant production from iron ore and/or sterile from its exploitation and/or tailings from its beneficiation, and/or fine and ultra-fine particles from other sources with similar properties, by agglomeration of these materials, and subsequent heat treatment, resulting from the combination of different …
Results show that both carbon content and melting temperature of the granule influence the final structure of the sintering bed. The obtained structural change of the sintering bed show that the proposed model is a potential tool to analyse the agglomeration phenomena occurring in the iron ore sintering process under various conditions.
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).
The beneficiated concentrates are fine-grained and need agglomeration before being used in the blast furnace. Amongst various processes used in agglomeration, sintering and pelletization are widely used in the iron ore industries. About 70% of the blast furnace feed is reporting from the sintering processes.
The use of pellet feed to adjust the chemical quality of the sinter is an alternative to the depletion of iron ore reserves. However, the addition of ultrafine in the sintering process can cause decrease of permeability and consequent drop in machine productivity. In this context, the present work investigated the addition of natural and ground pellet feed, evaluating its effects …
