Abstract
Device for pre-heating the raw cement powder, with several cyclones arranged in adjacency and/or in phases on top of one another, which are traversed consecutively by the exhaust gases of an oven, in particular of a rotary tube oven, and in countercurrent to the direction of transport of the raw material fed, whereby the raw material separated in the cyclones and falling downwards is in each case conducted to the cyclonic phase connected before the respective cyclone, by means of the hot gas pipe that empties tangentially in said phase, characterized, by the fact that in the first cyclone (3), located in the current direction of the exhaust gases of the furnace, and in all other cyclones (3) arranged on this cyclone has been arranged a turbulence chamber (6a and 6b respectively) that is in communication with the cyclone subordinated to it (3 or 5) by means of its immersion tube (7), and with the cyclone connected after es (13, 14), by means of the exhaust gas pipe (12a or 12b), and into which the discharge pipe (4) of the cyclone disposed above (5) opens out.
