    DORA STEHMANN IN WHITE CLIFFS (ARKANSAS, V. ST. A.).



  Shaft furnace for firing Portland cement, lime, etc. Like. With a drying drum connected to the preheater.



   The present invention relates to a shaft furnace for burning Portland cement, lime and the like. Like, with the same adjoining the preheater, rotating drying drum and the purpose of preventing the accumulation of the moist material entering the drum.



   In the drawing: FIG. 1 shows a vertical section through the oven, FIG. 2 shows a section along the line: 2-2 in FIG. 1 and FIG. 3 shows a cross section through the drying drum along the line 3-3 in FIG. l.



   The furnishing of the kiln is, as far as it is known, the following: The shaft A of the kiln is closed at the top by a vault B, the openings of which are closed during the regular operation of the kiln. Immediately below the mesh / there is an opening in the side of the shaft wall, into which the lower one

     In the drum ('according to the invention, in a central position there is a pipe G. which is open at its lower end to the furnace shaft and is provided with lateral openings G1 at its upper end, through which heated (rush from the shaft directly can get into the upper or feed end of the drum C. As a result
