Abstract
341,875. Rotary kilns. NIELSEN,N., 33, Vestergade, Copenhagen. Oct. 21, 1929, No. 31977. [Class 51 (ii).] Slurry is drained, granulated and then dried and partially or completely calcined by being preheated in a chamber wherein the combustion gases from the rotary kiln penetrate the granulated material. As shown, Fig. 1, the combustion gases leaving the kiln 1 pass downwards through a layer of the granulated material 3 supported on a movable grate 4, from whence the material passes via an elevator 5 to the kiln. The gases are removed by a suction fan 6. In further embodiments the material is supported on a travelling chain grate, and in a chamber fitted with a partition wall to deflect the combustion gases.
