Located in Lingwu City, Ningxia, it is affiliated to Shenhua Ningxia Coal Company, with a capacity of 6.0Mt/a thermal coal. The washing process uses heavy medium shallow groove, by-pass of the final coal and slurry pressure filtration recovery. The coal preparation plant is one of the representative works of thermal coal preparation plant because of its simple and practical process, flexible system and rich and adjustable product structure.

The scale is 4.5 million tons per year. 200-50mm lump coal is pre-discharged by intelligent dry separator, 50-1mm final coal is separated by desliming and pressureless three-product dense medium cyclone, 1-0.25mm coarse slime is separated by intelligent coarse slime separator, -0.25mm fine slime is separated by primary and secondary desliming flotation concentration, the flotation clean coal is recovered jointly by solid-liquid separator (screen settling centrifuge) and press filter, and the flotation tail coal is recovered by using a two-stage concentrated, coarse and fine particles respectively by a solid-liquid separator (screen sedimentation centrifuge) and a filter press.
