Nov 26, 2014018332Iron 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.
The pelletizing process is a process which contains numerous sub-processes, or process segments. On the way from the mine to a final product, the iron ore goes through the following main process segments 1 The iron ore is crushed and the waste rock is removed. About 85 of the particles should be less than 44 m in length, width, or height.
Jan 28, 2014018332Iron ore concentrate pellets are traditionally hardened at high temperatures in horizontal grates and grate-kiln furnaces. However, heat induration requires tremendous quantities of energy to produce high-quality pellets, and is consequently expensive. Cold bonding is a low-temperature alternative to heat induration.
