Asphalt Batch Mix Plant： After being poured into suitable hoppers according to the particle size, the cold aggregates are conveyed by a conveyor belt to a vibrating screen, where the cold aggregates with particle size larger than 4 cm are filtered out, and other cold aggregates are sent to the drying drum by a diagonal belt conveyor. Hot aggregates enter the elevator from the burner end of the drying drum after being dried and heated. With its help, hot aggregates reach the vibrating screens. Depending on the size of the mesh, hot aggregates are sieved to different silos. Through accurate weighing, the hot aggregates in different silos are batched into the mixer according to the ratio designated ahead. At some time, the mineral powder also falls from the screw conveyor, and the heated liquid bitumen also sprays from the nozzle. After mixing, the finished mixture is produced one batch by another.
Asphalt Drum Mix Plant：The drying drum of the continuous asphalt plant has functions of drying, heating, and stirring. The cold aggregates go into the non-stop rotating drum from the hoppers via a conveyor belt, in which cold aggregates are dried and heated in sequence. The nozzle in the drying drum continuously sprays the bitumen, and the mixture comes out unintermittedly with the drum rotating.
