| Abstract: | Conclusion from comparison in detail of two existing coal preparation plants in Panjiang mine region that coal cleaning by process of rougher-jig/cleaner-HM has the advantage of suitability for slime-water treatment,low medium consumption,and stability of product quality,and the disadvantage of complexity in process and relative low concentrate yield;that by process of all-HM has the advantage of simplicity in process,low energy consumption,and ease for automatic control,and the disadvantage of high medium consumption,difficulty in slime-water treatment,serious abrasion of equipment and pipeline,and high maintenance cost.On such analysis,options of cleaning process recommended for technical conversion for existing coal preparation plants in southwestern China. |
