Pelletizing. Pelletizing is a method for forming nearly spherical powders, based on roasting and consolidating green pellets prepared by adding proper amount of water and binder into fine materials or fine concentrates. Pelletizing is one of the important methods of agglomeration of iron ores, by which pellets are produced.

The heat hardening or "induration" of pellets employs one of the three conventional furnace types: vertical shaft furnace, grate-kiln system, and travelling straight grate. The latter process that was primarily developed by Lurgi and is currently owned by OutoKumpu Technology, accounts for two thirds of the world's installed

The plant took iron ore concentrate and produced superior iron ore pellets (which are spheres of high iron content and uniform quality) for blast furnace and direct reduced iron feed. Since then, Grate-Kiln systems have been used for over 50 plants, on both magnetite and hematite ores, with an installed capacity of over 115 million tpy.

High-pressure grinding rolls (HPGR) have gained great popularity in the mining industry in the last 25 years or so. One of the first successful applications of the technology has been in iron ore pressing prior to pelletization. Piston-and-die tests can provide good insights on the material response in an HPGR. This work analyzed …

Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is ...
