iron ore pellets manufacturing process by tunnel kiln

iron ore pellets manufacturing process by tunnel kiln

SPONGE IRON PRODUCTION FROM ORE -COAL COMPOSITE

Tunnel kiln furnace are evolving as an alternative to Rotary kiln process. Iron ore fines and the low grade beneficiated iron ore cake are directly used for manufacturing of sponge iron in tunnel kilns. The material bed in Tunnel kiln being stationary, it does not require high strength and thermal stability of the raw material.

Iron ore pelletizing - Outotec

This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don’t need beneficiated, fines which are generated can be pelletized and used instead of being disposed of. Iron Ore Pellets are formed from beneficiated or run of mine iron ...
