Development of Pellet

Charging of super fluxed sinter in combination of acid pellets in blast furnace is the common technique to improve the utilization of fines in iron making. Sintering has a size limitation, while pelletization can utilize ultra-fine iron oxides or concentrates, but it is involved with high energy consumption and production cost. Get price
