末煤重介分选自动化生产技术的研究与应用

Research and Application of Fine Coal Dense Medium Separation Automation Technology

结合重介选煤生产中存在悬浮液密度经常超出工艺要求、精煤产品质量不合格这一问题,重点介绍了可解决这一问题的悬浮液密度自动测控技术、煤泥含量自动测控技术、旋流器入口压力自动测控技术、介质桶液位自动测控技术、精煤产品灰分自动测量系统,以及末煤重介产品质量在线自动测控系统;最后总结了重介分选自动化生产技术的应用情况及今后的发展前景。

Combined with the problem, which the existing suspension density often beyond the requirement of the production process in the field of heavy medium separation, the quality of clean coal was unqualified.Mainly introduced automatic measurement and control technology of slurry density,automatic measurement and control technology of coal slime content, cyclone inlet pressure automatic measurement and control technology, medium level barrels of automatic measurement and control technology, plant products ash automatic measurement system and dense medium coal product quality at the end of the online automatic measurement and control system to solve this problem; Finally summarized the dense medium separating automation production technology application and development in the future.
