超声波在线粒度仪在水峪选煤厂的应用

Application of the ultrasonic online particle size analyzer at Shuiyu Coal Preparation Plant

为解决传统煤泥水处理过程中煤泥粒度和浓度检测方法存在的样品代表性不强、检测周期长、检测劳动强度大等问题,水峪选煤厂采用DF-CPSM超声波在线粒度仪对煤泥粒度和煤泥水浓度进行检测。应用结果表明:该设备运转可靠,浓度检测误差小于10g/L,粒度检测误差小于2%,检测精度满足要求,为浮选操作提供了有效参考。超声波在线料度仪可为选煤厂煤泥水处理过程的智能控制提供重要技术保障。

The problems with the use of the traditional methods for detection of particle size and concentra-tion of coal slime are poor representativeness of samples,long detection process and high labor intensity.To tackle the problems,Shuiyu Coal Preparation Plant opts for the use of the DF-CPSM ultrasonic online analyzer.Field application shows that the concentration detection error is less than 10 g/L and the particle size detection error is less than 2%,indicating that the analyzer can work reliably with an accuracy well up to the required level.Its successful use may serve as an effective reference for the operation of flotation process,and proves to be an important technical guarantee for the development of intelligent coal prepara-tionplant.
