Abstract: A hollow inverted frustum shaped rotary hopper is provided above the furnace top to receive the raw materials from a conveyor. Beneath the rotary hopper is disposed a hollow disc shaped impeller including a dish shaped central portion facing to the lower end of the rotary hopper and a plurality of wedge shaped vanes mounted on the periphery of the impeller for defining a discharge openings between adjacent vanes for throwing out the raw materials by centrifugal force. A stationary inclined chute means is provided including an annular hopper surrounding the impeller for charging the raw materials discharged by the vanes into the furnace top and inert gas is ejected into an annular gap defined between the covers of the impeller and the inclined chute means for preventing the gas in the blast furnace from leaking to the outside.
