Abstract Charging installation for a shaft furnace The installation has a rotary chute or oscillating chute distribution device and a storage hopper which is mounted on the vertical axis of the furnace. The discharge orifice of the chute is controlled by a dispensing means designed to increase or reduce the discharge cross-section symmetrically about the said vertical axis. To reduce the segregation of the particles, the storage hopper and the dispensing means are movable about the vertical axis and are mounted inside a sealed chamber, above which are located at least two locks, each provided with an upper sealing flap and a lower sealing flap, and the hopper and the bottom of each of the locks are in the form of a tapered funnel, the conical wall of which forms an angle of less than 30° with the vertical axis of the furnace.
