Zusammenfassung:	PURPOSE:To efficiently use powdery sintered ore without needing large scaled equipment, lowering charging capacity and bringing about any trouble to gas flow in a blast furnace. CONSTITUTION:A shield plate 2 is arranged on a screen B of each of ore storing vessels A1-A6 so as to be freely inserted and pulled out by a cylinder 1. By inserting/pulling the shield plate 2 into or out of the sintered ore segmented from the ore storing vessels A1-A6 according to the gas flow in the blast furnace, the layer of the sintered ore in an ore surge hopper is separated into the screened layer and the non-screened layer to be is store as the each layer and segmented out and charged into the blast furnace.
