Abstract
A dryer adapted for use in an asphalt plant. The dryer includes a drum having an inner wall and a flight having a proximal end connecting the flight to the inner wall of the drum and a distal end that is spaced apart from the proximal end. A first profile extends from the proximal end to the distal end of the flight and defines a flight shape. A notch is formed in the distal end of the flight, which notch includes a notch shape that is defined by a second profile. The second profile has a length L, a center point, and a portion that substantially approximates a conic section.
