PROBLEM TO BE SOLVED: To obtain the sufficient degree of sintering and to improve the yield of a product sintered ore by acting magnetic force to the flowing of a sintering raw material in the interval between a drum feeder and a pallet, impressing static electricity, attracting the magnetized sintering raw material to the lower layer side and much segregating the magnetized sintering raw material and powdery coke in the upper layer part on the sintering raw material on the pellet. SOLUTION: A sintering raw material 2 from an ore supplying hopper 1 is discharged by using a drum feeder 3 and supplied onto a pallet 5 in a Dwight Lloyd type sintering machine to form a sintering raw material layer 7. A magnetizing device (magnet) 6a is disposed at the back surface side of a sloping chute 4. Electrodes 9 are impressed to high voltage with a DC electric source 10 and the applied voltage is about minus 10-20 thousand volt. The raw material of the fine grain in the sintering raw material 2, particularily, powdery coke is affected to the static electricity and segregated to the lower layer side in the flowing. The magnetized sintering raw material and the powdery coke can simultaneously be segregated in the upper layer part 7a of the sintering raw material layer 7 loaded on the pallet 5.
