摘　　要：随着凹山采场的深度开发及高村矿石进入凹山选矿厂 ,处理的铁矿石性质变化很大 ,加之中、细碎设备老化和碎矿最终产品粒度在 3 0～ 0mm ,很难适应生产需要。介绍了对中、细碎设备进行技术改造的情况 ,改造后碎矿最终产品粒度降至 16～ 0mm。With the deep-going mining of Washan pit and the entry of Gaocun Ore into Washan Concentrator,the iron ore to be treated varied greatly in properties.In addition,the equipment for secondary and fine crushing was old.All this made it difficult to crush the ore to a final particle size of 30～ 0 mm to meet the production requirements.Technical reform was made to the equipment and the particle size of final crushed product has been reduced to 16～ 0 mm.Opinions on further reform are given.
