Asphalt plants are specially designed plants that were created especially to produce hot asphalt. To generate the asphalt, the plant must use raw materials like sand, fillers, bitumen, and aggregates. However, many of these must be added in specific proportions to make quality products. Keep reading while we discuss everything you need to understand about asphalt mixing plants.
One of the many attributes of the plant is that it easily heats the aggregates before mixing these with the bitumen and adhesive products. Within this part of the process, aggregates need to be sized uniformly to enable them to then be applied in conjunction with many other materials which come in different orientations. The two of these are then combined with coarser particles and fillers to generate top-quality asphalt.
Typically, batch mix plants usually comprise a good number of components. The very first main one is the cold aggregate feeder bin. Because the name suggests, materials are stored in them and they are then separated according to their sizes. The feeder belts are located underneath the bins along with a specifically created conveyor.
The conveyor is commonly used to maneuver aggregates from a belt into a specially designed drying system. The materials are then shipped to a vibrating screen where they can be separated depending on how big or small these are. Inside the drying drum(concreto asfáltico), there is a burner that removes the moisture before transporting them to achieve the desired mixing temperature.
After this is accomplished, they are then sent right into a tower where they pass through several different layers. The initial one is another vibrating screen that separates them to enable them to be stored according to their sizes. Following this part of the process, they can be stored according to size in various bins.
These bins are termed hot bins and they are located just beneath the screening unit. When aggregates are positioned inside the bins, they may be held for some time before they can be mixed in accordance with weight. After the mixing and weighing process, it is then finally released in the mixing portion of the plant. Both filler and bitumen are then released into the unit after they are weighed.
At the end of mixing, the latest mixture is released in the silo or trucks. To comply with environmental standards, special control devices that control the pollution released into the atmosphere are equipped on the plant. However, most asphalt plants tend to use filter bag units since it is cheaper.
Once the bags have been in use, fines are passed through them. During the process, the bags trap dust inside. Right after the asphalt plant filtered the fines, the dust is collected and then reintroduced into the elevator that runs to the aggregates.
Since we conclude, we now have just checked out what asphalt mixing plants are. We’ve also just checked out some additional information about how they work. If you’re contemplating expanding your company, an asphalt plant just can be quite a good investment. However, you’ll want to look for a reputable supplier before you can get your plant.
