Abstract
373,248. Cements. PONTOPPIDAN, C., 33, Vestergade, Copenhagen. Feb. 13, 1931, No. 4567. [Class 22.] In the manufacture of cement in a rotary kiln, the granular or pulverulent charge material is preheated and wholly or partly calcined before delivery to the kiln, in a chamber I through which other waste gases from the kiln and the charge material are passed alternately. The chamber 1 is fitted with heat-absorbing bodies such as chains 10 which, as shown, are carried by a vertically-movable beam 11 so that they may be lowered, for heating up, during passage of the hot gases from the supply ducts 2 to the outlet flue 3, and raised through the charge material to impart heat thereto. A damper 4 is provided in the flue 3 for cutting off the flow of gases before the raw material is fed to the chamber I from the shoot 5 ; in some cases the passage of hot gases may be continued during transfer of heat from the chains to the raw material. The bottom 6 of the chamber 1 and ducts 2 is formed with perforations 7 through which the preheated. material passes to a chamber 8 fitted with a conveyer 9 delivering to the rotary kiln. The chains 10 may be replaced by grates or by ribs or inclined surfaces down which the material slides by gravity. Continuous operation may be secured by the employment of a pair or a number of pairs of alternately operated preheating chambers.
