Iron Ore Pellets Induration Solutions - Metal 7
Iron ore green balls are soft and easy to break. So after the pelletizing and screening operations, iron ore pellets have to be hardened in a furnace through a firing process. Once fired, they can be handled, loaded in ships or trains and delivered to the end users.
Iron ore pelletizing Grate-KilnTM system
In a straight grate, the grate cars have to go through the drying and induration zones. So, a deep bed of pellets with a hearth layer is required. Another part of the Grate kiln system pro-cess flexibility is because there is only one burner. The kiln burner can use liquid gas, or solid (coal or biomass) fuels separately or in combination.
