Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel. ... Outotec pelletizing plants have a faster start up and better reliability than other plants in …
shaft kiln. The hard pellets (about 1-1 in dia.) were thought to be a suitable blast-furnace feed material and subsequent tests in a small experimental blast-furnace were encouraging. These results attracted the attention of iron makers all over the world and inspired some par-ticularly energetic and successful work in Sweden.3,4,37

Pelletizing shaft kiln. the production process will produce the pellets from iron ore concentrate or powder materials. so various countries mainly produce acid pellet ore. Roasting equipment (Shaft furnace) The shaft furnace is countercurrent flow heat exchange vertical roasting equipment.
Abstract The disintegration behavior and mechanism of iron ore pellet in simulated shaft furnace conditions were investigated in details. Effects of temperature, reducing gas and gangue compositions were emphatically discussed. It was found that pellet disintegrated acutely as reduced by H2/CO = 0.8 at 550 °C. Gangue minerals in pellet were proved to ease the disintegration in various degrees.

Blast furnace or shaft furnace feed should form a perme-able bed of material, permitting gas flow through it uni-formly at a high rate. Iron ore concentrates in the form of fines are not suitable because, fines tend to pack into a non-permeable bed and also they are likely to be carried away as dust by the high gas flow rates.
