Pelletizing is the technique of compressing or molding a material into the outline of a pellet. Iron ore pellets are spheres of typically 818 mm 0. 31 0. 71 in meant for deployment as primary substance for blast furnaces. They typically contain 67%, 72% fe and various additional material adjusting the makeup of chemicals and the metallurgic features of the pellets. Typically limestone, Dolostone and olivine is added and bentonite is employed for binder. The process of pelletizing combines blending of the fundamental component, Forming the pellet and a thermal treatment baking the soft raw pellet to hard spheres. The raw material is rolled into a ball, Then fired in a kiln to sinter the particles into a hard sphere. The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets, Decreasing the resistance to the air that flows up through the tiers of material during the smelting. The configuration of iron ore powder in a high-temperature smelting furnace is more tightly, Packed and restricts the air flow. This is why iron ore is preferred offered in the shape of of pellets rather than in the form of finer particles
