摘　　要：为解决宁东洗煤厂梅花井分厂洗选能力不足的问题,在对改造目标和原则确定的基础上,对系统内制约生产的设备进行技术改造。生产实践表明:技术改造后梅花井分厂洗选能力达到15 Mt/a,洗选能力净增3.0 Mt/a,且系统运行平稳可靠,完全满足矿井生产和火车装车的需要;设备故障率大大降低,系统能耗下降,节约了一定生产成本。To improve throughput capacity of Ningdong coal preparation plant Meihuajing branch,technological modification on equipment that are undersized is carried out on the basis of upgrade criteria and aim. The result shows that throughput capacity of the plant is increased by 3. 0 Mt / a and reaches15 Mt / a,the whole process system runs steadily and reliably,power consumption is lowered,breakdown of equipment rarely occurs,and that underground mine production and train loading can be satisfied completely.
