ABSTRACT:
A method and apparatus for the manufacture of calcareous bonding agents, particularly cement, through the burning of finely grained substances by means of hot gases. The finely grained materials in the form of a suspension pass through a preheating and calcining zone where ordinarily accumulations of alkali and chlorine leading to deposits and incrustations in the lines would occur. In order to minimize such deposit formation, a branch stream of suspended particles is removed from the main stream and the finely grained solid matter contained therein is burned to clinker in a separate reaction zone in suspension with a combustible gas. The airborne clinker thus produced may be eventually recombined with the clinker produced from the main line stream which passes through a rotary kiln.
