Type: Coking coal preparation plant
Scale: 3.6Mt/a

Process: The 50-0mm raw coal is fed into a three product heavy medium cyclone without desliming, classification, and pressure. The coarse coal slurry is sorted by the coal slurry heavy medium cyclone, the fine coal slurry is sorted by a flotation machine, and the flotation clean coal is dehydrated and recovered by a horizontal settling filtration centrifugal dewatering machine and a filter press. The tail coal slurry water is concentrated in a thickener and then dehydrated and recovered by a horizontal settling filtration centrifugal dewatering machine and a filter press. The washing water is closed loop, which is environmentally friendly and energy-saving.
