摘要
针对马脊梁选煤厂入洗双系原煤带来的煤质变化频繁、选煤系统介质系统稳定性差、介耗居高不下等问题,在分析其形成原因的基础上,依据现场生产情况,从生产工艺、人员管理等方面采取综合措施,通过改善脱介筛、浅槽、磁选机等设备工艺,有效解决了双系煤入洗带来的原煤重介耗损大的难题。工艺优化后,原煤介耗从1.8kg/t降低至1.4kg/t。
There occur some problems in dual system raw coal in Majiliang Coal Preparation Plant,including frequent changes in coal quality,poor stability of medium system,and high medium consumption.Based on the cause analysis and on-site production,comprehensive measures are taken in terms of production process and personnel management.The heavy medium consumption caused by the dual system coal has been effectively solved by improving equipment such as sculping screen,shallow groove,and magnetic separator.After the process optimization,the medium consumption per ton of the raw coal was reduced from 1.8 kg/t to 1.4 kg/t.
