PURPOSE:To simply and continuously segregate carbonic material on the surface layer part by supplying sintering raw material and the carbonic material on a sintering pallet through sieve faces of plural round bars arranged at different inclined angles to make an arch on the lower position sides. CONSTITUTION:Plural round bars 6 are arranged at different angles so that single or plural number of arch shapes are made on the lower position sides and the mutual interval between individual round bars at the upper part is larger than the interval at the lower part. The sintering raw material 1 is supplied on this charging device 5 through a chute 4 and classified through the sieve faces of the round bar 6 to supply on the pallet 8, and the raw material layer 9 suitably segregated is formed. Further, to the material at the position just before the above sieve faces or to the fine grains having passed through the sieve faces, the carbonic material or mixture 12 of the carbonic material and the sintering material is added through a carbonic material supplying chute 11. In this way, by segregating the carbon on the surface layer part 13, efficiency of the sintering is improved.
