Optimization practice of coal slurry system in Yongjin Coal Preparation Plant
Yongjin Coal Processing Plaht has low sales price due to high moisture of coal slurry and the influence of environmental protection and seasonal factors.In order to optimize the tailing slurry dewatering process and equjpment,the plant adopts ultra-high-pressure diaphragm filter press to replace the original fast-opening filter press,and replaces the original scraper transport equipment with belt conveyor,and at the same time matches with hammer crusher suitable for crushing of filter cake.After the technological transformation,the moisture of filtered coal slurry is reduced from about 28%to below 16%;the appearance of the product after cake crushing is even and loose,which can meet the sales of homogenized blended raw coal or medium coal;and it realizes no slurry,meets the customer's demand,and solves the problems of production and operation.
