摘　　要：本文研究了提高铁精矿冷固结球团矿强度的有效途径。结果表明：在适宜的铁精矿细度、混合料预处理方式与时间下，添加新型粘结剂ＮＢ─Ｉ，比“复合粘结剂”ＣＢ的抗压强度指标提高４５％以上，而膨润土不适于制备冷固球团。Abstract In this paper,the ways to improve the strength of cold-bond pellets from iron ore concentrates were investigated. It is shown that under the conditions of suitable fineness of iron ore concentrates and binder ias well as proper pretreatment of mixture,with the adding of new binder NB─I to replace CB, the compression strength of cold-bond pellets was increased by more than 45%,while bentonite is not suitable for preparation of cold-bond pellets.
