Type: Coking coal preparation plant

Scale: 6.0Mt/a

Contracting mode: partial contracting, new construction projects

Process: 50-0mm raw coal is fed into a three product heavy medium cyclone without desliming, classification, and pressure. Coal with a size greater than 0.25mm is sorted by a heavy medium cyclone, while coal with a size less than 0.25mm is sorted by a jet flotation machine. Flotation clean coal is dehydrated and recovered by a horizontal settling filtration centrifugal dewatering machine and a pressure filter. After the tail coal slurry is concentrated in a concentrator, it is dehydrated and recovered by a horizontal settling filtration centrifugal dewatering machine and a pressure filter. The washing water is circulated in a closed loop, which is environmentally friendly and energy-saving.
