摘要萤石尾矿含有15%~20%的氟化钙，在熟料煅烧过程中，掺入一定比例的萤石尾矿可明显延长熟料凝结时间，熟料初凝时间由原来的85~95min延长至205~304min，终凝时间由130~150min延长至267~387min。同时，改善了生料的易烧性，稳定了缓凝熟料的生产，优化了水泥性能，满足了特殊工程对缓凝水泥性能要求。

Abstract: Fluorite tailings contain 15% ~ 20% calcium fluoride. During clinker calcination, adding a certain proportion of fluorite tailings can obviously prolong clinker setting time, the initial setting time of clinker is prolonged from 85 ~ 95min to 205 ~ 304min, and the final setting time is prolonged from 130 ~ 150min to 267 ~ 387min. At the same time, the burnability of raw meal is improved, the production of retarded clinker is stabilized, the cement performance is optimized, and the performance requirements of retarded cement for special projects are met.

Key words: retarding clinker fluorite tailings burnability comprehensive utilization of resources
