The asphalt mixing plant, also named asphalt concrete mixing plant, refers to the complete set of equipment which is used for the quantity production of asphalt mixture. There are different asphalt mixing plants according to the different measuring standards.
Based on the transfer mode, the asphalt mixing plant is divided into mobile, stationary asphalt mixing plant and semi-stationary plant; based on the production technology, it is divided into the continuous drum and forced batch asphalt plant.
What’s more, the asphalt plants categorized on the basis of different measuring standards are able to implement the free combination such as mobile asphalt drum mix plant and mobile asphalt batch mix plant.
Mobile Asphalt Mixing Plant for Sale
The mobile asphalt plant for sale available in stock mainly has two types: the mobile asphalt drum mix plant and the mobile asphalt batch mix plant. A mobile asphalt mixing plant for sale refers to the plant that the storage bin and mixing tank are equipped with tires for easy movement, and it is applicable to county-level asphalt highways and low grade expressways.
Mobile Asphalt Drum Mix Plant
A mobile asphalt drum mix plant is the combination of the mobile asphalt plant and the (continuous) drum asphalt plant, integrating their respective characteristics. A (continuous) drum asphalt mixing plant is the plant that heating and drying of the cold aggregate and the stirring of mixture are continuously carried out in the same drum.
Thus the mobile asphalt drum mix plant is like the mobile asphalt plant not only suitable for these projects such as the county-rural roads, low grade highways, road maintenance and mountainous highway, but also has high productivity.
Mobile Asphalt Batch Mix Plant
A mobile asphalt batch mix plant not only has the function of a typical mobile asphalt plant, but also has that of an asphalt batch mix plant. An asphalt batch mix plant is the equipment that the components (macadam, sand, limestone powder and asphalt) are relatively measured accurately in a certain proportion, fed in batches and mixed forcibly.
The production of the asphalt batch mix plant can summarize in this way: measurement in batches–feeding in bitches–forced mix in batches–discharging in batches. A mobile asphalt batch mix plant is the main supporting equipment for asphalt pavement construction.
Because of its perfect structural characteristics, correct gradation, high measurement accuracy, good quality of finished materials and simple control, it has played an important role in the construction of asphalt pavement, especially expressway.
Mobile Asphalt Mixing Plant Price
The price of an mobile asphalt mixing plant is to be influenced by these factors such as the asphalt plant types, production capacity, finished material bin types, burner types and so on. The price of mobile asphalt mixing plant ranges from $150,000 to $3,500,000.
Continuous Mix Asphalt Plant
The continuous mix asphalt plant can be briefly described in following words: the proportion of raw materials are controlled by the adjustment of cold aggregate, mixing of mixture is carried out continuously.
To be more specific, the continuous (drum) mix asphalt plant is the plant that heating and drying of the cold aggregate and the stirring of mixture are continuously carried out in the same drum. The production process of the asphalt mixture is that each component (gravel, sand, stone powder, asphalt, etc.) is continuously and dynamically measured in proportion, and continuously fed and drum drop mixed.
Portable Asphalt Plant
The portable asphalt plant is the best choice when the working site needs to be changed frequently without affecting production schedule. It aims to maximize mobility and meet the various needs of road contractors looking for high quality machines.
The portable asphalt plant is on the chassis to facilitate rapid installation and start-up. One of the key advantages is that there is no need to set up the foundation, which can save the extra costs.
Asphalt Mixing Plant Near Me
There mainly exists two basic types asphalt plant near me: continuous drum type and forced batch
(or intermittent) type according to technological process (or mixing mode).
The continuous (drum) asphalt mixing plant near me is the plant that heating and drying of the cold aggregate and the stirring of mixture are continuously carried out in the same drum. The production process of mix asphalt is that each component is continuously and dynamically measured in proportion, and continuously fed and drum drop mixed.
A batch asphalt mix plant near me refers to the plant that the production of asphalt mixture is carried out batch by batch.
Asphalt Plant Drum Mixer
An asphalt plant drum mixer generally refers to the combination of drum dryer and aggregate mixer for the continuous asphalt mix plant.
Different from the asphalt batch mix plant, the drying and heating of cold aggregate and mixing of mixture are respectively carried out in two different assembly devices — drum dryer and mixer, while the drying, heating and mixing of cold aggregate for the asphalt continuous mix plant are carried out in the same assembly device — drum mixer.
Asphalt Production Process
After the central control room sends the boot command, the cold materials in the cold bin are first transported to the drum dryer through the belt conveyor.
Then the aggregates dried are transported to the vibrating screen for screening via the hot material elevator, and the screened aggregates fall into each hot aggregate bin.
Next the powders and screened aggregates drop into the corresponding weighing hopper from the outlet of the respective storage bins, are measured by the electronic scale, and are dropped into the mixing tank.
Last the weighed hot asphalt is also sprayed into the mixing tank. After various mixtures are fully mixed, the mixed bituminous material is produced and it’s unloaded into the hopper car.
It is unloaded into the bituminous mixture storage bin through the track, and finally the mixed material is placed on the transport vehicle through the unloading gate.
