DEVICE FOR PRODUCING EXPANDED GRANULATED MATERIAL
The invention relates to a 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 (10), wherein at least one feeding means 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. According to the invention, at least one rotatable shaft insert (11) is provided, which is arranged at least in sections in the furnace shaft and has at least one scraper blade (12) which forms with an inner wall (13) of the furnace shaft at least one gap (14) having a gap width (18) and which is designed, during the rotation of the at least one shaft insert in an operating state of the device, to remove caking (15) on the inner wall at least in sections if a thickness (16) of the caking is greater than the respective gap width.
