CFS Density Separator creates a fluidized bed of 1.60 specific gravity. It creates a quasi heavy media with sand as the media. Lignite floats and overflows, accompanied by sand finer than the cut point. The lignite passes over a sieve where the +30 mesh lignite is discarded and the fine sand is saved.
A DSM SCREEN working in conjunction with a Density Separator will remove contaminants, Such as:
