Coal Dryer Technology

Coal Dryers Carrier Vibrating Equipment, Inc.

A coal dryer for lignite should include explosion venting, a water deluge system and possibly an inert gas or a re-circulated self-inerted process gas. Conversely, anthracite coal exhibits a high ignition temperature, rendering explosion vents or a deluge system in the coal dryer unnecessary. Carrier coal dryers can treat:get price

Coal Dryer Kilburn

Rotary Dryer A rotary dryer can be used, however, the generation of fines is high. These are vey low RPM dryers and hence the drying is inconsistent i.e. the dried coal does not have uniform moisture. Tornesh or Flash Dryer Maximum particle size limited to 6 mm.
