drying and preheating processes of iron ore pellets in a traveling grate

Iron Ore Pellets and Pelletization Process | ispatguru.com

Iron Ore Pellets and Pelletization Process 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.
