High Batching Accuracy, Stable Quality
Batch weighing and forced mixing ensure that the gradation and bitumen-aggregate ratio of each batch strictly meet the design requirements. This is the fundamental reason why it can be used for high-grade highways.
Good Flexibility, Strong Adaptability
The production recipe can be easily changed to quickly produce asphalt mixtures of different specifications and types. It also has stronger adaptability to changes in raw material particle size.
Excellent Environmental Performance
The complete baghouse filter system effectively controls dust emissions, meeting stringent environmental protection standards.
Mature Technology, High Reliability
As the most classic structural configuration, its technology is highly mature, with a relatively low failure rate and convenient maintenance.
Feeding and Drying
Cold aggregates are preliminarily proportioned in the cold feed bins, then conveyed by the belt conveyor into the drying drum to be dried and heated.
Elevating and Screening
Hot aggregates are lifted by the bucket elevator into the vibrating screen, where they are screened by particle size and stored in the corresponding hot bins.
Precise Weighing
Under the command of the control system, each hot bin, filler silo, and bitumen tank discharges material into their respective weighing hoppers according to the recipe, achieving precise weighing.
Mixing
All weighed materials (aggregates, filler, bitumen) are sequentially fed into the mixer for forced mixing.
Discharging
The finished mixture is discharged into the finished product silo, waiting to be loaded into trucks for transport to the job site.
At this point, one cycle is completed, and the plant immediately begins the next cycle.
