Zusammenfassung:	1437704 Preheaters for cement burning kilns KLOCKNER-HUMBOLDT-DEUTZ AG 12 Dec 1974 [14 Dec 1973] 53779/74 Heading F4B Apparatus for burning a fine-grained material e.g. cement, comprises a rotary kiln 1 and a preheating system having a number of cyclone separators, the hot gas flow from the kiln to the preheating system being divided into at least two channels 5, 6, each of which has a pipe 7, 8, for injecting fuel, which burns in the gas flow, heating the material to a temperature sufficient to effect calcination before it enters the kiln. The preheating system is preferably divided into two independent systems, each having an input 11 for raw material and an outlet 12 for exhaust gases. At the end of the preheating system the material is fed along lines 9 and 10 to the hottest parts of the channels 7 and 8, afterwards being separated by the final cyclone and fed to the input chamber 4 of the kiln over line 3.
