CONTINUOUS ASPHALT MIXTURE PRODUCTION PLANT

A continuous asphalt mixture production plant based on double-horizontal-shaft forced mixing comprises a cold aggregate bin (1), a continuous aggregate conveying and metering system (2), a drying drum (3), an aggregate elevator (4), a double-horizontal-shaft continuous mixing host (5), a continuous asphalt metering and conveying system (6), a continuous powder conveying and metering system (7) and a finished product bin (8). The double-horizontal-shaft continuous mixing host comprises a first double-horizontal-shaft mixing cylinder (51) and a second double-horizontal-shaft mixing cylinder (52) connected in series. The first double-horizontal-shaft mixing cylinder is provided with an aggregate inlet (511), an asphalt inlet (512), a powder inlet (513) and a first discharging port (514), and the second double-horizontal-shaft mixing cylinder is provided with a mixture inlet (521) and a second discharging port (522). The aggregate inlet, the asphalt inlet and the powder inlet are respectively connected with an outlet of the aggregate elevator, the continuous asphalt metering and conveying system and the continuous powder conveying and metering system correspondingly. The first discharging port is interfaced with the mixture inlet, and the second discharging port is connected with the finished product bin. The present application has large output, prolongs the mixing time and improves the mixing uniformity of the previous and later materials.
