USA1 Process and system for dry coal separation by coal ...

The process for coal separation includes two steps of size grading and oversize raw coal separating. A size range is obtained through size grading, then the obtained raw coal is separated by a sensor system, and coal briquettes with high impurity contents are blown into an impurity chamber through highspeed compressed air, thus improving the separating accuracy and efficiency.

Thermoadhesive Separation: a Novel Dry Coal Beneficiation Technique

Beneficiation of coal (separation of ash minerals from coal) is generally achieved using the waterbased processes. Most of the preparation plants utilizes gravitybased processes, such as jigs, heavy media vessels, cyclones, spirals, etc., for particles down to a size of 28 mesh ( mm). The finer size (minus 6 mm) is beneficiated either by ...
