pelletizing grinding iron ore
Pelletizing - Assignment Point
Pelletizing of iron ore. The principle behind pelletizing processes is the opposite of grinding technology: it consists of gathering together or clustering fine solid particles in order to form elements of larger dimensions. Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.
