Title (EN) PRODUCTION OF CALCINED LIME FROM NATURAL CHALK MATERIAL IN A ROTARY KILN
(FR) PRODUCTION DE CHAUX CALCINÉE À PARTIR DE MATIÈRE DE CRAIE NATURELLE DANS UN FOUR TOURNANT
Abstract: front page image
(EN)Disclosed is a method for calcining a natural chalk powder within a rotary kiln. The powder is inserted into the kiln accompanied by an additive that promotes nodulization of the powder to thereby facilitate the treatment of the chalk powder within the rotary kiln. The nodulization takes place at temperatures less than the calcining temperatures of the chalk and prior to the nodulized chalk being calcined within the kiln.
(FR)L'invention concerne un procédé de calcination d'une poudre de craie naturelle à l'intérieur d'un four tournant. La poudre est introduite dans le four accompagnée par un additif qui favorise une nodulisation de la poudre pour faciliter de cette façon le traitement de la poudre de craie à l'intérieur du four tournant. La nodulisation a lieu à des températures inférieures aux températures de calcination de la craie et avant que la craie nodulisée ne soit calcinée à l'intérieur du four.
