PROBLEM TO BE SOLVED: To provide a raw granulated material to be sintered showing high strength in any one of a water condensation zone and a drying zone in a sintering bed of a sintering machine, when the raw granulated material is produced into sintered ore. SOLUTION: The method for drying the raw granulated material to be sintered comprises the steps of: adding a dispersive agent such as sodium polyacrylate in an amount of 0.01 mass% or more by a solid content after having been dried, to a raw material to be sintered as a granulation accelerator; kneading and granulating the mixture; and drying the grains into a water content of 4% or less.
