摘要： PURPOSE:To enable the control of the stock level in a relay hopper by using screening meshes having different mesh openings for the screening under containers for the raw materials to be charged into a blast furnace and adjusting the respective using ratios thereof. CONSTITUTION:Raw materials to be charged into a blast furnace are seieved to large lumps 10 which are plus mesh and small powder 11 which is minus mesh by screens 1'-8' provided to the bottom of containers. The lamps 10 are weighed with weighing devices 9 and are then fed into a surge hopper 19, from which the lumps are charged with a conveyor 23 into the blast furnace according to a charging schedule. On the other hand, the powder 11 is fed into a small lump hopper 14, where the powder is separated to small lumps 12 and powder 13. The lumps 12 are fed into a relay hopper 16. The desired amt. of the small lumps in the hopper 16 is weighed with a weighing device 18 by a feeder 17 with respect to the charging rate of the large lumps 10. When the time for charging the lumps 12 comes according to the charging schedule, the lumps 12 in the device 18 are fed to the hopper 19, from which the small lumps are charged with the conveyor 23 into the blast furnace.
