    Jan 17, 2018 ABSTRACT. Drying is a critical process step to achieve excellent pellet quality in pelletizing process. The complexity and energy consumption toward moisture removing, especially for highly hydrated iron ore, increased the need for breakthrough enhancements to this process.The preparation of iron ore pellets begins with the crushing and grinding of iron ore into a fine powder, and adding reducing additive coke (C) and binding agents and mixing. The mixture is added to a pelletizing machine or ball mill along with a pre determined amount of moisture to form green pellets.

  • Lotta Casey Organic Binders For Iron Ore

    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 layers of material during smelting. This is the reason that iron ore is referred in the form of pellets rather than in the form of finer particles. 3.Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 67 72 Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolostone and olivine is added and Bentonite is used as binder The process of pelletizing combines mixing of.

    Pellets are primarily used in blast furnaces and are also used in DR plants. Occasionally pellets are used in the steel process. Pellets are stored in bunkers before charging to the blast furnace. The mixture of iron bearing materials (iron ore rubble, sinter and or pellets) and additives (flux material) are known collectively as the burden .Drying, downdraft drying, preheating, firing, after firing and cooling zones. A major advantage of the traveling grate is that the green pellets remain undisturbed throughout the process. LKAB is an international high tech minerals group, one of the world’s leading producers of upgraded iron ore products for the steel.
