OBTENER PRECIO >>Iron ore pellets can be made from beneficiated or run of mine iron ore fines. Lean iron ores are normally upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized so that it can be used in an iron making process. Also during the processing of high grade iron ores which do not need beneficiation, generated fines can be ...

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. Ore ...

Through crushing, grinding, and various other techniques, low-grade iron ore is frequently upgraded to a concentrate product in the form of a powder. If processed directly, this powder would reduce the efficiency of the overall steel making process, including blast furnace performance; therefore, pelletizing of the fines is essential to process efficiency.
