Dry Coal Separators Dry Coal Processing Separators

The FGX dry processing of coal is a density based method. A typical FGX separator consists of a coal feeder, separating compartment, blower, draft fan, and dust collecting system. The separating compartment includes a perforated deck, vibrators, air chamber, and hanging mechanism. FGX has sold over 2,000 units in over 17 countries around the world proving its success in cleaning coal from

Dry Cleaning of Pulverized Coal Using a Novel

A cleaner coal product can be obtained if a dry process is avaialble to further clean pulverized and thus better liberated fine coal at the power plant prior to its combustion. In this study, a novel rotary triboelectrostatic separator (RTS) was investigated for its application to dry cleaning of fine coal samples acquired from the power plants in the state of Illinois.

Commercially available dry separation technologies such as air tables and air jigs are mostly effective in cleaning coarse coal with particle size larger than 6.35 mm. The smaller-than-6.35 mm fraction, which might be up to 20 to 40 percent of raw coal, is sent to the clean coal or tailings streams in a dry separation plant without any cleaning.
