Pelletizing
Pelletizing is a method for forming nearly spherical powders, based on roasting and consolidating green pellets prepared by adding proper amount of water and binder into fine materials or fine concentrates. Pelletizing is one of the important methods of agglomeration of iron ores, by which pellets are produced.
