• There are several iron ore pelletizing processestechnologies available in the world. However currently Straight Travelling Grate Process and Grate Kiln Process are more popular processes. • The pellet plant in eastern region use either travelling grate technology with dry grinding or Grate Kiln technology with wet grinding technology.
Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore coke or anthracite coal can be added to the mix to work as an internal fuel to help .
preparation of the green pellets are iron ore limestone ben-tonite and Corex sludge. The chemical analysis of the raw material is shown in the Table 1. Iron ore ﬁnes and lime-stone of 10mm size were ground separately in laboratory ball mill. Green pellet mix was prepared by mixing the iron ore ﬁnes limestone bentonite and Corex sludge .
Iron ore pelletisation. BRPL is in operation in producing iron ore pellets from iron ore concentrates after beneficiating low grade iron ore fines. The low grade fines with Fe less than 56-57 are beneficiated at beneficiation plant through grinding gravity amp; magnetic separation process to produce high grade iron ore concentrates with 63-64 Fe.
Raw material for pellets is produced by crushing and grinding low-grade iron ores—typically of the taconite class and finer than 325 mesh 0.044 mm—and magnetically separating the iron oxide magnetite Fe Iron ore pelletization ScienceDirect2015-1-1 15.1.
