简介:摘要原煤在生产过程中混入各种矿物杂质,在开采和运输过程有不可避免地混入顶板和地板的岩石和其它杂质,从而使原煤中矸石量增加、灰分提高、末煤及粉煤含量增长、水分提高。为减少原煤中的杂质,使煤炭按质量和规格分成各种产品,就需要采用选煤加工过程。选煤就是利用煤炭具有的与其他矿物质不同的物理、化学性质,应用物理和化学方法使原煤中的灰分、硫分和矸石等杂质的含量降低,并加工成质量均匀、用途不同的成品煤的加工技术。选煤厂作为煤炭企业的重要组成部分,掌握以洗煤过程(如跳汰、重介、浮选)为核心的多种工艺与技术。因此,选煤厂的监控和管理,主要工艺过程参数的检测,对于稳定产品质量、提高精煤产率、减轻工人劳动强度、改善作业环境,具有重要的意义。
