Compulsory Type Mobile Asphalt Mixing Plant

The compulsory type mobile asphalt mixing plant is a mobile asphalt mixing production equipment integrating aggregate drying, heating, screening, weighing, mixing, dust removal and other functions.
 

The main structural components of the compulsory type mobile asphalt mixing plant include:
- Mixing host: usually adopts forced mixer, which can quickly and evenly mix asphalt, aggregate and other additives.
- Aggregate silo: used to store different types of aggregates (e.g. sand, stone, gravel, etc.), usually equipped with vibrating screen or grading device.
- Asphalt storage tanks: used to store liquid asphalt, usually equipped with a heating system to keep the asphalt fluid.
- Measuring system: Used to accurately measure the weight of aggregates, asphalt and other additives to ensure that the mix ratio meets the requirements.
- Control System: Usually an automated control system that monitors and regulates the parameters of the production process in real time.
- Mobile chassis: The forced mobile asphalt mixing plant is usually designed to be movable, which is easy to transfer between construction sites.
- Discharge system: used to discharge the mixed asphalt mixture, usually equipped with lifting device.

The working principle of compulsory type mobile asphalt mixing plant mainly includes the following steps:
- Aggregate processing: Aggregates of different grain sizes are transported to the aggregate silo via conveyor belt or bucket elevator, and then transported to the drying cylinder for drying and heating as needed.
- Asphalt handling: Asphalt is conveyed through an asphalt tank or asphalt storage tank to an asphalt doser, ready to be mixed with the dried aggregate.
- Mix weighing: The automatic metering and batching station weighs the materials such as aggregate, asphalt and stone powder according to a preset formula and in a certain proportion.
- Mixing and stirring: the weighed materials are sent into the double horizontal shaft forced mixer for mixing, through the forced stirring effect of the mixing blades, so that all kinds of materials are fully mixed.
- Finished product storage and transportation: the mixed asphalt mixture is transported to the finished product silo by conveyor belt or bucket elevator for storage, and then transported to the construction site as needed.
 

The advantages of the compulsory type mobile asphalt mixing plant include:
- Strong mobility: the mobile asphalt mixing plant comes with tires or walking mechanism, which can be easily moved to different construction sites and is suitable for county and township roads and low-grade highway projects.
- Small footprint: due to the modular design, the components of the asphalt mixing plant can be compactly installed together, greatly reducing the footprint.
- Short installation period: the installation and dismantling process of the asphalt mixing plant is simple and quick, which can be put into production quickly and improve the construction efficiency.
- High degree of automation: the adoption of advanced automation control system realizes automatic weighing, conveying, mixing and discharging of materials, reducing manual intervention and improving production efficiency and product quality.
- Good mixing quality: Double horizontal shaft forced mixer has the advantages of high mixing efficiency and good mixing uniformity, which can produce high quality asphalt mixture.
- Accurate metering: the automatic metering batching plant adopts high-precision metering sensors and programmable controllers, which ensures the accuracy of material proportioning.
- Environmental protection and energy saving: the asphalt mixing plant is equipped with dust removal device and combustion furnace with high combustion efficiency, which reduces the emission of dust and harmful gases and meets the requirements of environmental protection. Meanwhile, it reduces energy consumption by optimizing the combustion and mixing process.
- Convenient maintenance: the main components of the asphalt mixing plant are reasonably designed, easy to maintain and repair, reducing the cost of use.
 

To summarize, the compulsory type mobile asphalt mixing plant has the advantages of strong mobility, small footprint, short installation period, high degree of automation, good mixing quality, accurate metering, environmental protection and energy saving, and convenient maintenance, which is an indispensable and important equipment in modern road construction.
