Finer aggregates may also be added along with mineral fillers. There are 2 main types of asphalt mixing plants: continuous mix plants and batch mix plants. Both forms of plants produce asphalt their difference is found in the process employed to produce said asphalt.

Working Principles Of Asphalt Batch Mixing Plant

1. Raw, unheated aggregates from different storage bins are fed to the cold aggregate feeder.

2. The aggregates are moved in to the drying drum using a conveyor system.

3. The burner fueling the drying drum ensures the aggregates are dried effectively with heat.

4. The plant is fitted with a primary dust collector. That collector is designed for filtering heavy dust particles, so there exists less pollution.

5. As soon as the aggregates are dry, they may be relocated to the tower unit by way of a bucket elevator.

6. Towards the top of the tower unit is actually a multi-layered screening unit. As hot aggregates move through the multiple screens, they get addressed with the screening effect.

7. Separate hot bins are widely used to store different kind of aggregates.

8. Bitumen is stored and heated in special tanks that come with pumping equipment. The bitumen is pumped in the weighing hopper.

9. The aggregates are weighted and discharged in to the main mixing unit. Within the mixer, filler materials and bitumen are mixed with the aggregates.

10. After mixing to the required time, the recent asphalt is able to be employed. It is actually typically discharged into waiting tucks, but it can also be shipped to temporary storage silos.

11. The whole plant is controlled via a computerized user interface.

Parts Of An Asphalt Plant

1. Primary vibrating screen

2. Cold feed bins

3. Charging conveyor

4. Hot aggregate bucket elevator: The bucket elevator is made up of an extensive, covered structure with a lot of buckets linked to a chain system. The heated aggregates are transported to the top level of the tower in this elevator unit.

5. Drying drum with burner: Perhaps the most important part of the plant(planta de asfalto venta). It can be compromised of your rotating drum and burner unit. The rotation ensures the aggregates are heated up evenly.

6. Pre-separator with bag filter: The bag filter is commonly used to get rid of harmful dust particles and toxic gases through the plant's emissions.

7. Hot bins

8. Multi-deck vibrating screens

9. Mixing unit: The mixing unit ensures each of the raw materials are combined effectively to the correct duration. Mixers are normally jacketed so that the contents remains hot and prepared for discharge.

10. Weighing hoppers: The weighing hoppers are very important for ensuring the correct proportions of raw materials are shipped to the mixing drum.

11. Bitumen storage tanks: Direct heating type tanks are equipped with a burner. Meanwhile, indirect heating type tanks utilize an internal hot oil coil system for heating the bitumen.

12. Cpanel: PLC panel by using a touchscreen display and interface for quick oversite and charge of the plant.

13. Filler storage silo/hopper
