Portable Asphalt Mixing Plant

Portable asphalt plant actually means mobile type asphalt mixing plant. It is specially designed for construction projects of short construction period, less project quantities, construction site is uncertain and needs to change sites quickly and frequently. We can understand portable asphalt mixing plant from two aspects: asphalt mixing plant and mobility. Firstly, asphalt plant refers to a complete set of equipment used in batch production of asphalt concrete, it can produce asphalt mixture, modified asphalt mixture and colored asphalt mixture. Therefore, asphalt batch plant is key equipment in highway construction, classified highway construction, urban road construction, airport construction and port construction, etc. As for mobility, small asphalt plant is easy to assembly and disassembly and convenient to transport. Because it adopts modular design and mobile chassis. And according to the construction period, it can transfer flexibly in different construction sites, which greatly reduces equipment transport costs. This portable asphalt plant for sale has been the ideal choice of asphalt mixture product for small and medium-sized road construction projects, because of its energy-saving environmental protection, fast and effective performance. Moreover, the installation of small asphalt plant for sale can be accomplished in four hours, and the plant will be equipped with asphalt tank and finished product storage bin, which will reduce the construction period and construction costs. We are experienced portable asphalt plant supplier, we have many sorts of small asphalt plants for sale for your reference.

1. Cold aggregate batching system. Each outlet of the hopper is equipped with materials shortage alarming device, when two fine aggregate material hoppers are lack of materials, it will alarm and vibrate hoppers automatically. The batching machine adopts frequency control, performance is reliable. The external and internal of the belt conveyor are equipped with cleaning device to remove adhesive particles materials of the belt conveyor and avoid scratching the belt. Middle filter sieve can remove large-volume aggregate effectively and avoid bigger wastes entering into the drying cylinder, it is beneficial to reduce the heat loss and prevent the blocking of hot aggregate elevator and vibrating screen.

2. Drying system. Outer wall of the drying drum is 50mm thick insulation layer, there are various lifting blades set in the drum, which is good for heat exchange of aggregate and flame and maximizes thermal efficiency. The drying drum is driven by four friction wheels, universal connection, steady transmission and uniform force.

3. Burning system. The installation and maintenance is very easy and convenient. It is not necessary to connect draught fan and air pipe. Small asphalt mixing plant is equipped with gas ignition device, pressure atomization and achieve adequate burning.

4. Hot aggregate elevator. Discharge port adopts special structure, which reduces the wear and lowers the noise. At the bottom of the hot aggregate elevator is tightening device, which is convenient to adjust the tightness of the chain, the installation, change and maintenance of hopper.

5. Vibrating screen system. Four layers design is convenient to maintain and change. In vibrating screen system, hot aggregates will be proportioned according to different size of the materials.

6. Hot aggregate storage bin. After proportioning the hot aggregates, acceptable materials will enter into the hot aggregate storage bin and wait for being weighed.
7. Weighing system. There is pressure releasing pipeline in the hot aggregate weighing hopper. Each hot aggregate hopper adopts three-point-type suspension, with transportation fixed part. Filler weighing can be added cumulatively. First weigh and then convey, this method improves the weighing accuracy, conveying speed and evenness, meanwhile, reduces the mixing period. Asphalt weighing system adopts pressure spraying, speedy and even, which shortens the mixing period and boosts the production.

8. Asphalt supply system. Asphalt pipeline is protected by the conduction oil, it has advantages of good insulation effect, reliable usage and easy maintenance. In addition, it is convenient to use the diesel oil as the fuel.

9. Filler supply system. At the bottom of filler hopper and recycling hopper is air breaker pneumatic device, which can effectively avoid pack set of the filler hopper. Add butterfly bamper at the discharge port of the screw conveyor to control impulse; add hand valve at the discharge port of the filler hopper, which is easy to maintain; recycling filler can be discharged together, which effectively reduces the pollution of the construction site.

10. Dust collecting system. Dust of volute casing collector will enter aggregate elevator and be used as aggregate, dust of bag dust collector will enter filler elevator and be reused; we use imported NOMEX needled-punched felt, waterproof and oil-repellent; ash removal of dust collector is under automatic control, pulse back flushing can clean the bag automatically; it has over temperature alarming function, and there is cold blast valve, after over temperature, can add cold air to protect bag.

11. Mixing system. The blender we adopt is designed by European technology; liner and mixing blades are made from high chromium wear-resistant materials, therefore, they have a long service life; the machine is driven by double reducers, two shafts rotate adversely to make the aggregate much more even.

12. Finished product storage bin. There are two kinds of finished product storage bin: side type and beneath type.

13. Electric control system. Drum type small mobile asphalt plant can only be controlled manually, while the batch type small scale asphalt plant can be controlled by the computer.

Working principle of portable asphalt mixing plant

In fact, the working process of small portable asphalt plant is an integration of three materials: filler, asphalt and cold aggregate.

Cold aggregate usually means gravel, cold aggregate will be conveyed to the drying drum through the tilted belt conveyor, after the heating and drying, the hot aggregate will be lifted to the vibrating screen through the hot aggregate elevator, in this process, produced filler will enter the recycling hopper through the dust collector, and then, after screening, large-scale aggregate will be removed, and acceptable aggregate will enter the hot aggregate storage bin, then the hot aggregate will be discharged to the weighing system and after the weighing system, aggregate will enter the mixing cylinder.

Meanwhile, filler will enter filler hopper, and filler and recycling filler will enter the filler weighing system together, and after weighing, they will be discharged to the mixing cylinder. Asphalt will be pumped to the asphalt tank through the asphalt pump, afterwards, asphalt will be discharged to the asphalt weighing system, and after the weighing, proportioned asphalt will be conveyed to the mixing cylinder. Three materials are in the mixing cylinder, under the control of the electric control system, they will be mixed for several minutes. And then, finished asphalt mixture will be discharged to the finished product storage bin, once asphalt mixture is in need, discharge the asphalt mixture to the asphalt transportation truck and convey them to the construction site.
