Flotation clean coal is dehydrated and recovered using a combination of a screen settling centrifuge and a filter press. After the tail coal slurry is concentrated in a high-efficiency thickener, it is dehydrated and recovered using a horizontal settling filtration centrifugal dewatering machine and a filter press. The washing water is circulated in a closed loop, which is environmentally friendly and energy-saving.
