Extruded asphalt pavement milling material crushing and screening device
The invention discloses an extruded asphalt pavement milling material crushing and screening device which comprises a heating and conveying system and a crushing and screening system, wherein the heating and conveying system comprises a drum; a milling material is rotationally conveyed from a feed chute in the rear end of the drum to a discharge chute in the front end of the drum by virtue of the drum, and a heating device for heating the milling material is arranged on the drum; the crushing and screening system is arranged below the discharge chute and is obliquely arranged; the crushing and screening system comprises a crushing operation group consisting of multiple rotatable crushing units; and the milling material dropping onto the crushing operation group is extruded by the rotating crushing units and is collected by a screen. According to the device disclosed by the invention, a single and extensive RAP treatment mode in pavement hot regeneration in the conventional highway reconstruction and expansion can be effectively improved, further, the mix proportion design of hot recycled asphalt mixtures is further conveniently realized, and the pavement performance of the regenerated asphalt mixture is improved.
