such as iron ore, additives and binders. Pretreatment process of Iron Ore Fines In the pretreatment process, iron ore fines are ground into finer size, suitable for green ball formation. Dry or wet grinding process is adopted for grinding the iron ore fines. In dry grinding process, equipment drier, ball mill,
Most iron ore processing takes place in the fine particle size ranges and is often carried out on a wet basis. However, some iron ore resources are located in dry areas where adequate water supply is very difficult to obtain and hence dry processing is the only option.
1. Introduction. For iron ore sintering technology, the granulation of iron ore particles is a highly important stage prior to the hot processing unit [1, 2].By means of granulation, the raw iron ore particles are agglomerated into the products with an appropriate size distribution, which guarantees the desirable green bed permeability and air flow rate for sintering [3].
The raw materials are wet milled for 10 h to obtain the desired fineness. The slurry obtained is screened, dried at 110 °C, powdered to break the agglomerate and granulated to small nodules for better compaction.
The ore will be crushed and processed at the site for the production of magnetite, dry process rejects, and wet tailings. The processing plant will use dry crushing and grinding circuit. The plant will employ the KB 63130 type gyratory crushers, which will be the largest crushers in the country.
