Iron Ore Pelletizing - Iron Ore

Iron Ore Pelletizing Pelletizing is the kind of process which is compressing or molding a material into the shape of a pellet. Iron ore is one of the vast ranges of different materials which are pelletized. Iron ore pellets are like the spheres which their size typically between 8–18 mm (0.31–0.71 in). They are as raw material for blast furnaces.
