摘　　要：采用顺流式回转窑烘干煅烧一体的一步法工艺可将磷石膏制成石膏粉。介绍磷石膏在烘干煅烧装置中的烘干、煅烧、粉碎过程存在的问题及技改措施。技改后，石膏粉的日产量提高了100t以上，煤耗由85kg/t降低为65～68kg／t，石膏粉相组成改善，达到建筑石膏粉国家标准。The gypsum powder is produced from phosphogypsum by one- step process of integrated drying and calcining. The existing problems of drying, calcining and smashing process, as well as the technical transformation are introduced. After transformation, the yield of gypsum powder is increased more than 100 t per day, coal consumption is decreased from 85 kg/t to 65-68 kg/t, the phase composition of gypsum powder is improved achieving the national standard of building gypsum powder.
