How Does An Asphalt Mixing Plant Work?

It is utilized to heat, dry cold aggregates, and blend them with bitumen, RAP, and other binders as per diverse recipes to produce different final mixtures for road surface paving.

1. Feed cold aggregates into different bins according to the particle size.

2. The collection conveyor belt below bins and an inclined conveyor belt successively transfer them to the drying drum.

3. After dried, the hot materials come out and enters the elevator, which transports them up to the screening system.

4. The hot aggregates get separated by multiple-layer vibrating screens.

5. They enter into temporary storage bins, the number of which is equal to that of screens.

6. They are released to the mixer below in accordance with the dosing weights set on the control panel.

7. Simultaneously, bitumen and optional mineral fillers are also weighed and released into the mixer.

8. After mixed for less than 20 seconds, the final mix is discharged into the waiting truck or the special storage silo.
