To provide a charging method of sintering raw material, with which the segregating state of the sintering raw material charged on a sintering pallet is improved.
An opening part 3 is arranged at the downstream side of a dropping position 11 on a charging chute 4 for sintering raw material 13 supplied from a feeder 2 and also, a gas blowing nozzle 12 is arranged above the opening part 3, and middle and coarse granular sintering raw materials 16, 17 and fine granular sintering raw material 14 are separated by blowing the gas to the sintering raw material 13 from the gas blowing nozzle 12. The separated middle and coarse granular sintering raw materials 16, 17 are slidingly dropped on the charging chute 4 and charged into a sintering pallet 6. When the fine granular sintering material 14 is dropped onto the surface layer from the opening part 3, an angle γ forming the advancing direction of the blowing gas from a gas blowing nozzle 12 to the flowing direction of the sintering raw material 13 during slidingly dropping on the charging chute 4 is regulated to 80-100°.
