Preparation of Iron Ore Micro-pellets and Their Effect

2018-6-13  In hybrid pellet sintering process, iron ore concentrate of relatively finer size is first converted into micro-pellets and these micro-pellets are used in place of iron ore fines. The prerequisite for micro-pellets to be used in hybrid sintering is to have sufficient green strength so that they does not get disintegrated during mixing with other raw materials and during charging on the sinter machine.

2016-7-1  Similarly, Nyembwe et al. reported that a partial replacement of iron ore fines by concentrate and micropellets results in a complex granulation mechanism. It was found that the incorporation of concentrate and micropellets in sinter feeds produce granules with smaller Sauter mean diameter.

Development of fluxed micropellets for sintering

Ultrafine iron oxide wastes such as slime, blue dust and Linz–Donawitz (LD) converter sludge have very limited use in sintering of iron ore due to their excessive fineness (−50μmm). Pelletisation of these ultrafine materials for use in blast furnace involves high temperature curing, which is a highly energy intensive process.

Iron Ore Sinter - an overview ScienceDirect Topics

Iron ore sinter /pellets are redirected from the wall of the blast furnace to the center using the bell-less top charging equipment. The top gas utilization (TGU) improves from 47.5 to 49.0% (an increase of 1.5%) due to better contact of the ferrous burden with the CO-rich gas in the furnace center.
