Practice of process transformation for filter press feeding and coarse cutting in Yangchangwan Coal Preparation Plant
This article elaborates on the installation of vibrating arc-shaped screens,material distribution boxes,and collection chutes in the coarse coal slurry recovery system of the Yangchangwan Coal Preparation Plant's block coal washing system.The inlet and outlet pipelines are also modified,the screen gap size is adjusted,and the working conditions of the hydraulic cyclone are adjusted.On the premise of ensuring that the coal moisture content(Mt)of the product meets 17.5%,the yield of particles larger than 0.45 mm in the pressure filtration coal slurry is reduced to below 2%,meeting the assessment requirement.
