A shaft furnace, particularly a blast furnace, includes a furnace head having a gas pipe extending substantially centrally therefrom. A charge distributing means in the furnace head includes a frustoconical bell associated with a reversely directed frustoconical pan normally resting on the bell. The bell is rotatable and vertically displaceable. When the bell is moved downwardly, a lip on the pan engages a fixed support so that the bell separates from the pan for charging of the material into the furnace. Charge storage and conveying means are interchangeably associated with the furnace. The charge material is delivered into the storage means by a simple pouring operation, and is released to fall substantially freely into a self-supporting pile at one end of a conveyor which extends transversely between the storage means and the furnace head, and is pressure sealed. The conveyor preferably slopes slightly from the storage means to the furnace head, and means are provided to seal off the furnace head when the conveyor and the storage means are disconnected from the blast furnace.
