Abstract (en)
[origin: EP0038314A1] 1. A heat-exchanger unit for preheating ground raw material for making cement, comprising a riser pipe (9, 11) which receives a hot gas stream and serves as a mixing chamber (20) for mixing the hot gas stream with the ground raw material, which is supplied by a supply duct (22), said pipe opening into a cyclone dust-collector (10, 12), which is provided at its top with a discharge duct, preferably an immersed pipe (23), for delivering the hot gas stream from which most of the ground raw material has been removed, and is provided at the bottom with a duct for the discharge of the ground raw material which has been collected, characterized in that the riser pipe (9, 11) constitutes a diffuser (21), which adjoints the mixing chamber (20) at its top and transforms the hot gas stream into a laminar stream.
