Abstract (en)

The present invention relates to a rotary cylinder dryer (10) for mixtures of virgin inerts and recovery materials (RAP) for preparing bituminous conglomerates, which comprises a cylinder (11) which is associable with motor means (14) suitable for driving it in rotation around its own longitudinal axis (A) and which is provided with two opposite heads (16, 17), an inlet mouth (18) of a mixture of virgin inerts and of recovery material (RAP) to be dried and which is defined at one of the two heads (16), an outlet mouth (19) of the dried mixture and which is defined at the other one of the two heads (17), at least one burner (20) associated with the head (17) at which the outlet mouth (19) is defined and a tubular body (23), open at the opposite ends (23a, 23b), fixed inside the cylinder (11) and placed coaxially to the longitudinal axis (A) of the cylinder (11), with one of its open ends (23a) facing the burner (20) and at a definite distance from it, and which is characterized in that it comprises at least one auxiliary tubular body (24), open at the opposite ends (24a, 24b), fixed inside the cylinder (11) and placed coaxially the longitudinal axis (A) of it and in succession to the tubular body (23).
