ABSTRACT:
An asphalt plant which includes a drum having an axis of rotation, a mechanism for introducing materials into one end of the drum, a mechanism for discharging the materials from a second opposite end of the drum, and a heater for establishing a relatively high temperature zone through which the materials travel during drum rotation. A sinusoidal heat transfer tube is defined by opposing loops and conducts heat from the high temperature zone to the discharge end of the drum. The heat transfer tube thereby increases the efficiency of the asphalt plant by burning less fuel and more uniformly distributes heat throughout the drum, particularly at the discharge end thereof.
