摘要
The mixer has a drum (3) rotated by a motor (10-12) about an inclined longitudinal axis (A) and defining an upper end (4) and a lower end (5), which is concentrically surrounded by a stationary cylinder (14) defining an interspace (15). A burner (35) located at the lower end (5) internally heats the drum (3) and a hopper (20) is provided at the upper end (4) for introducing aggregates into the drum (3). The drum (3) also has a funnel (23) for the introduction of recyclable asphalt pavement (RAP) and blades (26) for transferring the mixture from the drum (3) into the interspace (15). Ducts (43, 44) are located proximate to the upper end (4) for the introduction of bitumen, filler and additives into the mixture, and fins (39) are connected externally to the drum (3) for mixing and conveying the material to a discharge outlet (40) at the lower end (5) of the cylinder (14).
