摘要
为解决葛店选煤厂入选原煤不能有效分级及入选粒度超出主选设备要求的问题,对原煤分级系统、块煤系统、末煤重介系统、粗煤泥系统、浮选系统进行技术改造。经过工艺改造和设备更新后,全厂产能大幅提升,精煤得到高效回收,经济技术指标可观。
In order to solve the problem of the raw coal not effectively classified and feed size beyond the requirement of primary cleaning equipment in Gedian coal preparation plant, the technical reformation has been carried out on raw coal classification system, lump coal system, small coal dense medium system, coarse slime system and flotation system. By the technical reformation and replacement of equipment, the productivity of Gedian coal preparation plant increased sharply, clean coal recovered efficiently, and achieved favorable economic and technical indicators.
