摘　　要：宝山矿业公司山下选区破碎系统经过多年运行,存在设备数量多、技术水平低、维护成本高等问题,通过对现有破碎工艺流程现状考察分析,查找出影响破碎作业指标的因素。对现有破碎流程进行改造,将原有破碎流程由“三段一闭路”改为“两段一闭路”,增设HP800细碎机实现两种破碎机匹配转车,开展筛板尺寸优化。改造后大幅度降低了入磨机粒度,为后续磨选作业创造了有利条件,同时减少了设备数量,降低了设备维检工作量,每年可创造综合效益854万元。After years of operation,there are such problems for the crushing system in submontane dressing area of Baoshan Mining Co.as large number of equipment,low technical level and high maintenance costs.The factors affecting crushing operation indexes are found out through investigating and analyzing the current situation of existing crushing technology.The existing crushing circuit is transformed,the original crushing circuit is changed from“one closed circuit each three sections”to“one closed circuit each two sections”,add HP800 fine crusher to realize the matching running of two types of crushers and carry out the size optimization of sieve plate.The particle size of entering grinder is greatly reduced after the transformation,which creates favorable conditions for subsequent grinding and separation operations,the number of equipment as well as workload of equipment maintenance and inspection are reduced so that the comprehensive benefit of RMB 8.54 million yuan per year can be created.
