There are two major categories of the asphalt mixing plant: the mobile type and the stationary type- this is based on the transport method. As the name implies, the stationary asphalt mixing equipment is always fixed on the construction sites. The mobile asphalt mixing plant can meet the requirements of constructions – unlike the stationary type.
When it comes to highway construction, for instance, it involves the long-distance transportation of necessary hot-mixed asphalt. And this is where the mobile asphalt mixing plant comes in. It can ensure continuous batching for such a project. Its portability is one of the primary reasons why this mobile asphalt mixing machine is popular among many users.
What Are the Main Parts of a Mobile Asphalt Mixing Plant
Generally, the plant has several components, such as:
1. Dryer Drum
The primary role of this dryer drum is drying cold aggregate. The aggregate’s drying level can directly affect the final product’s quality. Because of this, the dryer drum is built with heat-resistant and anti-weary materials that ensure a long life span. The advantage of the insulating layer is to reduce the heat loss within the dryer drum, save on fuel usage, and, in turn, enhance heating efficiency. There is also an outlet that comes with a temperature measurement device to control the cold aggregate’s temperature automatically.
2. Burner
It can ignite automatically and is not only safe but also convenient and reliable. Since the burner’s temperature can be controlled automatically, it enhances the aggregate temperature’s stability.
3. Mobile Cold Aggregate Supplying
Typically, the cold aggregate feeding hopper, as well as the aggregate belt, are installed on the mobile chassis. This ensures quick feeding and transportation. And since it comes with the frequency speed regulator, the feeder can guarantee an efficient and smooth running process. The discharge door of its hopper consists of an alarm device that inhibits aggregate from reaching the hopper. Additionally, the hopper’s vibrating screen can also filter a much larger aggregate to guarantee an effective supplying process.
4. Hoister
The anti-weary component can lower the hopper’s abrasion. The transmission of the hoister is also accompanied by a mute device, and this minimizes noise pollution.
5. The Control Room
Generally, there are advanced components within the electric control system, with high reliability, durability, and efficiency. The control room is usually mounted on the chassis to allow quick transportation from one location to another.
6. Mixing Tower
The mixing tower typically consists of asphalt weighing, weighing hopper, mobile asphalt mixer, vibrating screen, and hot aggregate storage bin. The bin contains a large capacity to guarantee quick feeding. You can also adjust the feeding proportion correctly. The asphalt mixing tower comes with a safety protection device. Modularization of the tower can ultimately make the plant achieve fast installation and transportation.
7. Dust Catcher
The dust collecting system is made up of the bag dust collector, as well as the dust catcher. It entails multi-stage availability and ensures top-quality finished products. Additionally, the bag dust collector has an insulating layer to prevent bag condensation. The inlet to the bag dust catcher is accompanied by a temperature protection device to primarily prevent bag damage.
8. The Finished Products Storage Bin
Typically, a large finished product bin is applied for storing ready-mixed asphalt and is fairly easy to handle. There is also an automatic control device on the discharge gate to prevent bonds.
