Device for producing expanded granulated material
Device for producing expanded granulated material (2) from mineral material (1) in the form of grains of sand with an expanding agent, comprising a furnace (3) with a furnace shaft (4), which has an upper end (5) and a lower end (6), wherein a conveying section (7) extends between the two ends and passes through a number of heating zones (8) arranged separately from one another in a conveying direction (12), wherein at least one feeding means (10, 11) is also provided, in order to charge at least the unexpanded material into the furnace shaft at one of the two ends in the direction of the other of the two ends. The invention provides at least one directing element (13), which is at least partly arranged in the furnace shaft, wherein the directing element forms a gap (15) with an inner wall (14) of the furnace shaft, at least in the region of one of the two ends, wherein the at least one feeding means is designed for charging the material into the gap.
