Iron Ore Pellet - an overview | ScienceDirect Topics

In this route of iron making, the use of noncoking coal or natural gas is made as reductant for iron ore. The oil is used for heat hardening of iron ore pellets which is generally exploited by gas-based DRI plants. The coal-based DRI units generally require lump ore which need some electrical energy during crushing and sizing operations.

Variables Affecting Iron Pellet Properties

Variables Affecting Pellet Properties: Pellet making is a complex process, requiring careful attention to the successive stages of feed preparation, balling, drying, firing, and cooling. Thus although the properties of the finished pellets are developed during the thermal induration or firing stage, the firing time and temperature are not the only variables which affect pellet properties.
