Every day, you probably interact with asphalt on a regular basis. From the roads that you drive on to get to and from work to the parking lot where you leave your car during the day, the surfaces are most likely covered with this versatile paving material.
Asphalt is prepared by mixing together a variety of different ingredients in a specific combination. This usually includes aggregates like sand and gravel as well as liquid bitumen, a viscous form of petroleum that is not only black in color but also extremely sticky.
These ingredients are mixed together in one of two different types of plants: drum plants and batch plants (Асфальтосмесительные установки). Drum plants make large quantities of asphalt that can be stored for several days. This asphalt is usually loaded onto trucks and hauled to the job site. To ensure that the asphalt maintains its viscous state, it is kept in special heated silos.
Asphalt batching plants, on the other hand, are designed to mix small quantities of asphalt as they are needed. Instead of being stored for future use, each batch of asphalt created by these plants is used right away on a project. This is in contrast to drum plants where the asphalt is stored and used over a longer period of time.
These plants contain a few key components. (Устройства асфальтных заводов)Aggregates are loaded into cold feed bins at one end of the batching plants. These bins measure the amount of aggregate that is added to ensure that the finished mix has the correct ratio of the various aggregates.
Each cold feed bin is used for a different size or type of aggregate. There is also a conveyor belt attached to each bin that is used to move the aggregate from the bin to the drying drum.
The drying drum is a special rotating cylinder that is used to heat up the aggregate. This helps remove all traces of moisture, thoroughly drying it out. As the aggregate is dried, a variety of gases are given off. These gases are released through a special bag filter, helping to limit the emissions given off by the batching plant.
Once the aggregates have been thoroughly heated, they are then coated with liquid bitumen. This creates the final asphalt mixture that can then be used for a variety of different paving applications. (Какие поставщики асфальтных заводов бывают в Китае)
Asphalt batching plants are often portable, meaning that they can be used right at the job site. This eliminates the need to haul asphalt from far away, helping to minimize transportation costs for the project. It also helps avoid wasted time since there is no need to worry about having to drive the asphalt through traffic to get it to the job site.
This basic introduction to asphalt batching plants should give you a better idea of how they work. You can also find videos of the entire process online. Sometimes, watching a video is a great way to get a better sense of exactly how a piece of highly specialized equipment like an asphalt plant works.
