High pressure grinding rolls (HPGR) have been used for more than 20 years to grind iron ore pellet feed. Besides coarse comminution (crushing), where HPGR are installed upstream of the ball mill, there are numerous flow sheets where HPGR are used after ball milling and dewatering for re- or finish grinding. There is a clear...
Shaft furnaces use pellets (produced in the same way as pellets for the BF), or lump ore. 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 3 O 4) from the siliceous gangue. The fine ...
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 & magnetic separation process to produce high grade iron ore concentrates with 63-64% Fe.
