This week’s photo shows a FEECO employee welding flights into a rotary dryer.
Flights are used to increase the efficiency of heat transfer between the material and the process gas. Flights pick up material from the material bed, and carry it over, dropping it through the gas stream as the rotary drum turns. This showering of material creates what is called a “curtain” of material flowing through the process gas, allowing direct contact between the material and the gas.
Sometimes also referred to as “lifters,” flight can be custom designed in order to create maximum heat transfer and meet the particular needs of the material being processed.
