Introduction to Iron ore Pellets and Pelletizing

Introduction to Iron ore Pellets and Pelletizing

The process is considered more efficient than making use of iron ore powder which does not allow the hot air to freely circulate and warm the ore to a uniform temperature For this reason the pellets are often preferable to fine iron ore products since the ability to achieve that balance in temperature is somewhat limited with the fine ore Sep 12 2018 Iron ore pellets Pellets are small and hardened iron balls with a diameter of 1020 mm and are used as raw material for ironsteel manufacturing The pelletizing process was commercially introduced in the world market in 1955 following the World War II scarcity of highgrade natural iron ore in the United States
