Description of Intelligent Asphalt Distributor
1.It's developed on the basis of our many years' design experience of road construction machinery and engineering equipment.
2.It specializes in spraying emulsified asphalt, diluted asphalt, hot asphalt, hot modified asphalt and various binder;
3.Be ergonomically-designed, easy-operated, economical and practical;
4.HTF pipe: HTF internal heating method ensures smooth liquid running and prevents asphalt from coke burning;
5.Manual spray: the rotation indicator reads asphalt pump rotation speed. The operator can count out the corresponding vehicle speed and asphalt rotation speed to different spray volume according to our specified formula;
6.Automatic spray: the operator only sets spray volume in the console and starts velocity meter, and then the automatic control system could regulate asphalt pump rotation speed according to the vehicle speed;
7.It gets through the strict detection of our operators, as a type of ideal economical road construction machinery (road surfacing machine);

Applications of Intelligent Asphalt Distributor
1.It is widely used to deal with upper and lower seal layer, prime layer, asphalt surfacing, asphalt penetration surface, fog seal layer and so on.
2.It is also able to transport liquid asphalt and other heavy oil.
