Introduction to Iron ore Pellets and Pelletizing processes
The typical properties of the iron ore pellets are given in Tab 1. Process technology. There are four stages involved in the production of iron ore pellets. These stages consist of (i) raw material preparation, (ii) formation of green balls or pellets, (iii) induration of the pellets, and (iv) cooling, storage and transport of pellets.

What is the Difference Between Pelleting and Pelletizing?
Pelleting produces an overall dusty product because the jagged, cylindrical edges rub against each other and break off. FEECO does not provide pelleting testing or equipment. Pelletizing is a non-pressure agglomeration method, whereby material fines tumble against each other in the presence of a binding agent.

Iron ore pelletization
Pelletizing differs from other agglomeration techniques in that the powdered ore is first formed into a "green" pellet or ball, which is then dried and hardened in a separate step, usually by heating. Green pellets are made by combining moist ore with a binder and rolling it into balls using either a pelletizing disk or a pelletizing drum.
