Optimization of the coal washing system at Liangshuijing Coal Preparation Plant

Liangshuijing plant used to operate with the troubles of mismatch between coal treating capacity and mine output,irrational distribution of rate of feed to both coarse and small coal washing systems and overload of coal slurry treatment system.Proceeding from an analysis of the present operating conditions,work is made on optimization of the original coal washing system through the use of the primary fines removal process,and making appropriate adjustment of other production processes.It has been found that the fine coal scalped off through the abovementioned process at a classification size of 4mm can be treated in a flexible manner,the treating capacity of the plant is enabled to be well matched up with the increased mine output,and the overall production system has become rational in layout,making it possible for the plant to operate with a much improved economic performancce.
