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。
In combination with heavy-medium coal preparation, there is a problem that the density of suspension often exceeds the technological requirements and unqualified quality of refined coal products. The paper mainly introduces the automatic measurement and control technology of slurry density, the automatic measurement and control technology of slime content, Automatic measurement and control technology of inlet pressure of fluid flow, automatic measurement and control technology of liquid level in drums, automatic measurement system of ash in clean coal products, and automatic on-line measurement and measurement system for quality of terminal heavy medium products. Finally, the application of automated production technology for heavy medium separation Future development prospects.
