Asphalt Mixing Plant

asphalt mixing plantAsphalt mixing plant is a kind of equipment, which is used to mix the proportioned aggregates into the asphalt mixture under the specified temperature. And its main purpose is to produce asphalt, modified asphalt mixture, colored asphalt mixture and meet the requirements of highway construction, classified highway construction, urban road construction, parking lots, airport construction and port construction, etc. And there are dazzling asphalt mixing plant manufacturers in construction machine market and as for our company, we have been engaged in innovation and creation of our machines for years, and with the long history and rich experience of production, we have redesigned our products and have optimized their performance, so we are confident that our products can satisfy you greatly, the following page will give you a detailed introduction about our asphalt concrete mixing plant. In addition, we mainly have asphalt drum mixing plant, mobile asphalt mixing plant, batch type asphalt mixing plant and stationary asphalt mixing plant for your selection.

And tilted belt feeding conveyor and finished product storage bin haven’t been labeled in this figure. But they also belong to the components of the asphalt mixing plant.

Working principle
The working process of asphalt mixing equipment is the combination of aggregates mixing, mineral powder mixing and asphalt mixing. And the first step is conveying all the materials to the mixing cylinder.

1.Aggregates conveying. Aggregates in general are broke stones stored in the cold aggregate supply system. At first, send the broke stones to the drying system through the tilted belt feeding conveyor, and after the drying and heating, the aggregates will be sent to the screening system through the hot aggregate elevator, and in the vibrating screen, aggregates will be divided according to the grain diameter and then they will be sent to the hot aggregates storage bin, and then send the aggregates to the aggregates weighing system, after the weighing, send them to the mixing cylinder. This is the process of conveying aggregates;

2.Mineral powder conveying. During the aggregates conveying, there is a drying process, and this process will produce some dusts, so these dusts will be collected by the dust collecting system and then enter into the recycling powder storehouse, at the same time, new mineral powder will be sent to the mineral powder bin, so mix them up and send them to the mineral powder weighing system and after the weighing, discharge the mineral powder into the mixing cylinder. And this is the process of mineral powder conveying;

3.Asphalt conveying. Asphalt will be pumped into the asphalt tank by the asphalt pump, by the way, asphalt tank plays an important role in keeping warm and heating. And then, send the asphalt to the asphalt weighing system and after the weighing, discharge the proportioned asphalt into the mixing cylinder. This is the process of asphalt conveying.
After those processes above finished, begin to mix them together in the mixing cylinder according to the designated time. And after finish mixing, discharge the asphalt mixture into the finished product storage bin. Finally, send the asphalt mixture to the construction site by the heated bitument tanker.

asphalt mixing plantDifferences of five kinds of machine
There are five main kinds of asphalt mixing plants.
1.Continuous drum type
This kind of machine adopts continuous production, aggregates drying, heating and mixing are conducted in the mixing drum and this kind of mixing method is with the characteristic of high mixing efficiency.
2.Batch type
For this machine, the process of aggregates heating and mixing are conducted forcibly and periodically. The machine mixes the materials in turn and the mixing time is 45 to 60 seconds per pot. And it is with the characteristic of good mixing quality.
3.Mobile type
The stock bin and mixing pot of the machine have tires and they can move with the transfer of construction site, and it is more suitable for county and country highway and low grade highway.
4.Semi-stationary type
This kind of asphalt mixing plant equipment is equipped on the several trailers, and they will be assembled in the construction site and applied to the road construction.
5.Stationary type
Asphalt mixer plant means to fix the operation site, and it also named asphalt concrete processing plant and is well suited to city road construction.

1.Modular cold aggregate supply system;
2.Fuel-efficient heating and drying system;
3.High strength plate chain bucket type hoisting system with zero decibel mute reverse device;
4.Screening system is established on the basis of strict experiment;
5.Weighing system with high accuracy and good stability;
6.Even and high effective large circulation solid boiling system;
7.The dust particle size can be adjusted and has high pressure pulse cloth dust-collecting system;
8.Vertical up and down modular new and old powder hopper, powder supply system has various powder conveying patterns;
9.Fast installation of modular asphalt supply system;
10.Finished product storage bin is with the characteristics of low rate of fault and good insulating effect;
11.Adopt international famous brand air compressor with large air volume and air control system with Germany FESTO pneumatic elements of high quality;
12.PC + PLC control system with independent intellectual property rights and easy operation.
