A charging device for being mounted above the top opening of a blast furnace body. The charging device includes a stationary hopper with a closable lower opening, and a rotary hopper with a closable lower opening with the rotary hopper being arranged below the stationary hopper. The device further includes a rotary cover for covering the top opening of the blast furnace body, with the rotary cover being supported and rotated by the rotary hopper. An annular gas sealing device co-operates with the rotary cover so as to provide a gas-tight seal of the top opening of the blast furnace body, and a rotary chute is supported and rotated by the rotary hopper. The rotary chute points downward into the blast furnace body and is pivotable about a horizontal axis.
