Evaluating Coal Separation Processes: Coal Preparation ...

2018-6-10  Abstract. Abstract. When evaluating the separation made by a coal cleaning device, particularly when examining new applications, it is important to have a procedure that is independent of the feed consist to the device and thus can show differences arising from various operating conditions. One such procedure is the generation of fractional ...

Coal Beneficiation - an overview ScienceDirect Topics

Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the quality of the product required.

PROCESS AND SYSTEM FOR DRY COAL SEPARATION BY

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 high-speed compressed air, thus improving the separating accuracy and efficiency.
