犹他开发有限公司与朱丽叶斯矿物研究中心共同开发了一种在线煤泥分析仪,可同时测量灰分和固体含量百分数。其工业性样机自1984年4月以来一直在皮克·唐斯选煤厂成功地运行。1985年又用于对一组粗煤泥浮选机进行自动控制。文中简要地介绍了这种阿希斯坎型(Ashscan)煤泥分析仪及其精度,讨论了使用此种分析仪前进行手动操作的局限性,以及根据阿希斯坎(Ashscan)信号对入料、精煤和尾煤流的灰分及固体含量进行分析,并通过计算机控制浮选机液位和加药量的情况,以保证在精煤灰分符合预定的指标的前提下取得最大产率。
Utah Development Co., Ltd. and the Julius Minerals Research Center have jointly developed an online slime analyzer that measures both ash and solids content. Its industrial prototype has been successfully operated at the Picke Downs coal preparation plant since April 1984. 1985 again for a group of coarse slime flotation machine for automatic control. The Ashscan slime analyzer and its accuracy are briefly described in this paper. The limitations of manual operation prior to using this analyzer are discussed, along with the analysis of Ashscan signals Material, coal and tailings ash ash and solid content analysis, and computer control of the flotation level and the amount of dosing to ensure that the premise of the coal ash in line with the predetermined target to obtain the maximum yield.
