For example, in the direct reduced iron (DRI) manufacturing process, the porosity of the iron pellets helps facilitate the reduction of oxygen in the kiln. This process is essential for producing high-quality DRI fem (ferrous metallics) with a grade of 80+. Moreover, the iron pellets have a mean particle size (MPS) of approximately 9.5-10 units.
