Abstract

The invention relates to an arrangement for discharging and mixing lumpy material from a shaft furnace comprised of a hollow body opening downwards and/or to at least one side for discharging the reaction material, in which hollow body screws are radially arranged, these screws having shafts of different lengths in one level and/or one screw being designed as through screw. One of the possible combinations of cantilevered shafts 2 of three different lengths is to arrange the shafts radially to form an octagon in shaft furnace 1, wherein the opposed cantilevered shafts 2 have equal lengths. The ""dead man"" area, i.e. the inactive space in the center of the shaft furnace, is extremely reduced by this combination.
