Type: Coking coal preparation plant

Scale: 1.80Mt/a

Contracting mode: design+complete equipment supply, new construction project

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 coarse and fine coal slurry is recovered by an arc-shaped screen and a coal slurry centrifuge, the fine coal slurry is sorted by a flotation machine, the flotation clean coal is recovered by a clean coal filter press, and the floating selected tail coal is concentrated by a two-stage concentration process. The tail coal slurry water is concentrated by a thickener and then combined with a horizontal settling filtration centrifugal dewatering machine and a filter press for dehydration and recovery. The washing water is circulated in a closed circuit, which is environmentally friendly and energy-saving.
