Introduction to Iron ore Pellets and Pelletizing processes
Induration of green pellets consists of three main steps namely (i) drying of green pellets, (ii) firing of pellets at around 1300 deg C to sinter the iron oxide particles, and (iii) cooling of hot pellets before discharging. During drying (temperature range of 180 deg C to 350 deg C), moisture content of the green pellet is evaporated.
