Pelletizing is a method of agglomeration, or particle size enlargement, in which material fines are processed into pellets or granules. Pelletizing is used throughout a multitude of industries to process thousands of materials from difficult to handle powders and fines, into easy to handle pellets.

On the other hand, dominating shaft technologies such as the MIDREX direct-reduction process require a complementary agglomeration step to transform the iron ore concentrate into a well-structured input material. Pelletizing is a fundamental resource for direct reduction and electric steelmaking, meeting the challenging demands of a …Web

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. ... Pelletizing is a process which follows dryblending. It is seldom used, although it gives better results and minimizes housekeeping, but ...Web

The pelletizing process implies the agglomeration of very fine (sometimes just several microns) particles to pellets of some millimeters in diameter in a humid particle bed.
