PROBLEM TO BE SOLVED: To provide a method by which pseudo particles effective for improving the reducibility and cold strength of sintered ore are stably produced with a drum mixer, and sintered ore having excellent reducibility can be produced with a high yield. SOLUTION: To a vertical line passing through the central axis of a drum mixer, the angleαopening to a direction same as the rotary direction of the drum mixer from the central axis is controlled to 60°, the angleβopening to a direction reverse to the rotary direction of the drum mixer from the central axis is controlled to 10°, and a limestone based raw material and a solid fuel based raw material are added from an exhaust port to mixed granules in the ranges prescribed by the angleαand the angleβon both the sides of the vertical line.
