ABSTRACT:
A dryer for use in an asphalt plant for heating and drying virgin aggregate and also pre-heating reclaimed asphalt products (RAP). A drying drum cylinder having a burner at one end heats and dries virgin aggregate traveling therethrough. A second cylinder near the burner surrounds the drying drum and creates an annular cavity. RAP is introduced and travels through the annular cavity and exits adjacent the drying drum aggregate exit opening. Heat given off by the drying drum increases the temperature within the annular cavity and heats the RAP traveling therethrough. Heated aggregate and RAP first come in contact with one another after exiting the annular cavity and the drying drum and are, thereafter, delivered to a mixing drum.
