摘要
针对大屯选煤厂浮选加药系统存在的问题,根据改造后的浮选生产工艺提出了新的浮选药剂测控方案。生产实践表明,新系统投入运行后,不仅减轻了工人劳动强度,提升了岗位操作自动化水平,并且提高了浮选尾矿灰分和浮选精煤产率,增加了企业的经济效益。
According to the problem existed in flotation agent adding system at Datun coal preparation plant, presents the new flotation reagent control scheme based on the reformed flotation process. After the new control system put into operation, it is reduced the labor intensity of workers, improved the level of automatic operation, increased the ash content of tailings and clean coal yield, and improved the econom-ic benefit of the coal preparation plant.
