Abstract (en)

[origin: WO9925881A1] The invention relates to a device for withdrawing lumpy material, especially lumpy material containing iron oxide and/or sponge iron, from a shaft furnace, especially a direct reduction shaft furnace. The withdrawal device consists of worm conveyors which protrude into the shaft furnace over the floor of the same. A number of worm conveyors are aligned along axes. The projection of said axes onto the horizontal cross-sectional surface of the shaft furnace or the imaginary extensions of the projection of the axes forms secants of the horizontal cross-sectional surface of the shaft furnace. Said axes extend at a distance from the central point of the cross section of the furnace.
