The limestone mixture is fed onto a disc pelletizer (pan granulator) where it undergoes tumble growth agglomeration. If a pre-conditioning step were not utilized, this is where the pelletizing process would begin. The limestone builds and grows gradually as it rotates on the disc, with material and moisture being fed at a controlled rate.

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.

Hence, they get coalesce together and form nuclei which grow in size and into ball shape. These forces responsible for the agglomeration of iron ore fines are generated in the balling disc due the rotational movement in the balling disc. When the solid particles come in contact with water, the ore surface is wetted and coated with water film.
