  • Pelletizing an overview ScienceDirect Topics

    Jan 01, 2012· 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.
