Abstract (en)
[origin: US4585354A] An elongated drum rotatable about its horizontal longitudinal axis is surrounded by a sequence of cylindrical screens having different size mesh openings. A burner is located at one end of the drum. A feeder delivers stone chips into the end of the drum opposite the burner, and another feeder delivers used paving asphalt into the end of the drum at which the burner is located. The asphalt feeder has an elbow which passes through the burner flame and an outlet located outside the flame. Openings at the burner end of the drum provide communication between the interior of the drum and an annular space between the drum and the screens. A chimney for discharging dust is located at the stone chips feeder end of the drum.
