Abstract
1449414 Preheating and burning cement POLYSIUS AG 20 Aug 1974 [2 Oct 1973] 36546/74 Heading F4B In the two stage burning of cement raw materials in a rotary kiln 6 and a suspension preheater 1 of the cyclone type, the formation of deposits due to the presence of low melting point compounds containing alkalis, chlorine and sulphur is alleviated by blowing in air towards the exit end of the kiln by fans 10 disposed on its periphery. The fans 10 are disposed at a distance from the end of the kiln of about 2-3 times its diameter. They may be so disposed that the aforementioned distance is variable.
