GEA flash dryer, partial gas recycling system, mineral drying, mild steel construction, unused, 2019

GEA Flash Dryer System rated for 26,996 pounds per hour water evaporation rate, Partial Gas Recycled system with Comenco Systems direct fired air heater, 42MM BTU/hr heat input. System takes wet material through 15 HP Lump Breaker and into 125 HP Double Paddle Mixer where it is mixed with dry recycle material from dryer. System includes (2) bag filters / dust collectors with rotary airlock valves, product falls into variable-speed augers. Auger feeds into 250 HP Disintegrator to break up agglomerated product. Wet product is introduced to high-speed Venturi where hot drying process air from the combustion chamber and is accelerated upwards into the Drying Column where the majority of the drying takes place. The drying air is drawn through the system by an 800 HP Recirculation Fan located downstream of the bag filters. Exhaust gas comprised of the products of combustion and evaporation is discharged from the drying circuit through the Bleed-off Damper. The excess gas is then sent to a Stack. Natural gas supply - 46,000 SCFH flow rate; Recycled air from dryer - 89,097 lbs/hr (211,745 ACFM); Heater outlet air - 247,504 lbs/hr (159,269 ACFM); combustion air flow - 24,500 lbs/hr (7,667 SCFM). Designed for use with bituminous coal and can be used for various other minerals. Mild steel construction.
