Title:
METHOD AND DEVICE FOR BAKING FINE GRAIN MATERIAL, PARTICULARLY CEMENT RAW MATERIAL POWDER
Document Type and Number:
Japanese Patent JPS5988349
Kind Code:
A
Abstract:
A method and apparatus for burning fine grained products, such as raw cement meal, wherein the product is preheated in a preheating stage, calcined in a calcining stage, and is burned into clinker in a clinker stage followed by cooling in a cooling stage. The heating of the largely calcined product in the temperature range of about 900 DEG C. to the beginning of alite formation which occurs at approximately 1250 DEG C. is carried out under the fastest possible temperature rise conditions and the clinker reaction is carried out in concurrent flow with the gas stream in the burning stage. The clinker is then graded into a coarse grained fraction and a fine grained fraction which are then cooled in separate coolers after separation from the gas stream.
