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. Though dryers are cheap, the crushing of coal to lower sizes cannot be avoided.

ROTARY DRYERS & COOLERS

Direct-heat rotary dryers can operate on fuel oils, natural gas, propane or coal. In addition, steam-heated clean air and flue gases may be used as a heating medium. Indirect-heat rotary dryers are available in steam tube designs and standard rotary models. When the standard rotary design is used, convection heat transfer is employed.
