The present invention relates to a method for manufacturing a blending raw material for manufacturing a sintered ore, which includes a step of preparing powdered iron ore, very finely powdered iron ore, and a bonding material; a step of blending the powdered iron ore, the very finely powdered iron ore, and the bonding material in a mixer; and a step of putting a mixture of the powdered iron ore, the very finely powdered iron ore, and the bonding material to a selective pelletizer to manufacture a selective pellet. The very finely powdered iron ore is blended below 20-70% of the total weight of the powdered iron ore and the very finely powdered iron ore. And the present invention can lower manufacturing costs and improve productivity by manufacturing a pellet with an excellent strength by using the very finely powdered iron ore such as a pellet feed. |
