Shenhua Bayannur Energy Co., Ltd. Coal Preparation Plant
Type: Coking coal preparation plant
Scale: 12.0Mt/a
Contracting mode: EPC general contracting, new construction projects
Process: The 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 collected by a horizontal settling filtration centrifugal dewatering machine and a pressure filter. The tail coal slurry water is concentrated in a concentrator and then dehydrated and recovered by a horizontal settling filtration centrifugal dewatering machine and a pressure filter. The washing water is circulated in a closed circuit, which is environmentally friendly and energy-saving.
